The transmission unit in any car needs timely maintenance and careful care. If this requirement is systematically neglected, then the onset of premature wear of the gearbox will become an inevitable phenomenon. Most Renault Logan owners in versions 1.4 and 1.6 seek to prevent premature failure of transmission elements.
It is this topic that the material indicated in this current article will be devoted to, and the gearbox shift diagram will also be given.
What are the types of transmission units?
For the Renault Logan model in versions 1.4 and 1.6, the manufacturer provides several options for equipping the car with gearboxes with different operating principles. All units have enviable reliability and provide driving comfort due to the smoothness and clarity of gear shifting.
Renault Logan is equipped with the following types of transmissions:
- classical mechanics
- robotic unit, made on the basis of a mechanical box;
- automatic transmission.
The maintenance of these complex units is entirely the responsibility of the owner and is not a difficult undertaking. We also add that the gearbox switching scheme has no differences.
For timely maintenance, it is required to clearly study the time intervals for replacing the transmission lubricant and the clutch assembly (or its elements).
How to service the transmission?
For proper maintenance of the Renault Logan box, it is required to comply with regulatory standards and follow clear rules during operation. There are several informative videos on this topic.
- During operation of the transmission unit, a slightly increased pressure of the air-oil medium is created in its crankcase, which can lead to leakage of lubricant outward through the seals. To prevent this phenomenon and to discharge excess air from the unit, a special element is used - a breather. It should be constantly taken care of its cleanliness and, in case of contamination, urgent cleaning measures should be taken.
- An oil change when the gearbox of a Renault Logan mechanic is required to be performed at least after 60 thousand kilometers. This need is caused by the constant wear of the rubbing elements of the transmission, as a result of which chips accumulate on the magnet located in the crankcase. The magnet requires periodic cleaning when changing the oil.
- The automatic transmission needs more care than the mechanics. A lubricant change will be required at an interval equal to 40 thousand kilometers. This is due to the presence of a large number of rubbing components in the unit, many of which are made of materials that are more susceptible to abrasion.
- It is recommended to entrust the procedure for disassembly and reassembly to a specialized service. To extend the life of the transmission, original oil should be used.
- The robot, like the machine, also needs to be given a little more attention. Relubrication and assembly of the assembly must be carried out in the same order. Here, too, it is desirable to monitor the condition of the breather and clean it in a timely manner.
Subject to the indicated regulations, units for Renault Logan are able to serve a very impressive period.
Final moments
As it turned out, the procedures for servicing an automatic transmission and if a Renault Logan manual gearbox are different. Subject to the regulations, when the automatic transmission is able to catch up with the mechanics in terms of resource.
If the box needed repair, then it must be carried out in a specialized service.
There are many videos on this topic that allow you to visually study the process and make sure that the material presented here is correct.
Our advice is the following - follow the required service intervals and repair Renault Logan units in a timely manner, only in this case the gearbox will last long enough, and the gearbox shift pattern is also important.
The Logan manual transmission is the most traditional for a front-wheel drive car. There are two types of boxes: with a 1.4L engine, JH1 is used, with a 1.6L engine, JH3 is used. By design, both gearboxes are identical and differ only in the size of the clutch housing.
The gear ratios of both gearboxes are the same. The box marking is on the bottom of the crankcase. By design, the boxes are two-shaft, with five forward gears and one reverse gear. They are structurally integrated with the differential and final drive. All gears have synchronizers. True, until mid-2007, there was a single synchronizer in 1st gear. This led to the fact that it was difficult, and sometimes impossible, without re-gassing, to turn on the first gear when switching. Later, the factory made changes to the gearbox, they began to install a double synchronizer in first gear (they were originally on the rest), and the problem with turning on the first one on the go was gone.
The design of the box is very simple. The input shaft is made as a block of driving gears, which are in constant engagement with the driven gears of all forward gears. The gears of all forward gears are helical, and the reverse gears are spur gears. Gears of 1-4 gears are made integral with the input shaft, the gear of the fifth gear rotates freely on the shaft. A fifth gear synchronizer is installed at the rear end of the input shaft. The output shaft is hollow, oil is supplied through it under the driven gears. The driven gears and synchronizers of 1-2 and 3-4 gears are located on the shaft. The fifth gear is mounted on the shaft with splines. On the side of the clutch housing, the bearing of the secondary shaft is roller, and on the side of the cover, it is ball bearing.
In general, the box for cars of the budget segment is very good. It is distinguished by clarity when turned on, a competent gear selection mechanism. You don’t need to “search” for speed, apply a lot of effort to the lever too. Compared to the same VAZ manual transmission boxes, Logan is just heaven and earth.
However, she also has a problem - the inclusion of reverse gear. For many logan drivers, it turns on with a rattle. This is not a malfunction, but a design feature due to the fact that the reverse gear has only a single synchronizer. To avoid rattle, you can follow some simple tips. Firstly, turn on the reverse speed only when the car is completely stopped. Secondly, fully depress the clutch pedal. Thirdly, turn on the reverse gear through one of the front ones.
The gear ratios of the Logan boxes are well chosen and, in principle, are average for cars of this class. The only exception is 4th gear, which is a little shorter than usual. To achieve a speed of 60 km / h (according to the speedometer) in 4th gear, you need to develop 2150 rpm. The gear ratio of 5 speeds is optimally matched, taking into account both engine power and fuel efficiency. At 3000 rpm (maximum torque of an 8-valve engine), the speed on the speedometer is 110 km / h (the navigator shows a little more than 100 km / h) - which is both economical and does not strongly contradict the traffic rules.
The Logan manual transmission does not have any common problems, the resulting breakdowns are individual and occur in isolated cases. Although, if you carefully study the Logan Club forum, you can find such cases. They can be associated both with the features of operation, and with the usual technical marriage. In general, according to experts, the average Logan box during normal operation can go up to 300 thousand kilometers without any problems.
The issue of oil is interesting. According to the official regulations, the oil in the box is filled for the entire period of operation, but mechanics still recommend changing it every 80-90 thousand kilometers, this will extend the life of the unit. In some cases, changing the oil helps to solve problems associated with difficulty in choosing gears. The required volume of the transmission is 3.3 liters. Changing the oil in the Logan gearbox is a simple matter. There is a drain hole (under the "8 square") and a separate filler neck. You need to pour it until it pours back out of it.
It is difficult to check the amount of oil in the box - there is no dipstick. It can only be determined by the drain / fill method, therefore it will be useful to regularly monitor possible oil leaks on the box. There may be several sources of leakage, but most often it is a left-hand drive. The design feature is such that its internal CV joint is lubricated with oil from the box. And if there are any problems, the oil goes away.
Usually the lack of oil is manifested by the rumble of the box when driving. First in 5th gear, and then in all the others. If you notice an oil leak in time and fix it, you can do without consequences. But prolonged operation of the box without oil will almost inevitably lead to its breakdown.
Many newcomers who have just bought Logan pay attention to the strange rattling of the car at idle. If you squeeze the clutch pedal, then the rattling disappears, so many tend to blame the gearbox for this. In fact, rattling is a feature of the native release bearing and has nothing to do with the box. The rattling does not bear any consequences either for the clutch or for the box. If you happen to change the clutch, then a new kit will fix this problem.

Transmission (gearbox) Renault Logan is a vital unit that ensures smooth start, stop and speed changes. With proper operation, the service life of the device is hundreds of thousands of kilometers, and premature wear is a sign of gross errors in maintenance and untimely repair of related components.
Types of gearboxes in Renault Logan
The French manufacturer has provided several gearbox options that are reliable and easy to use. During production, the following types of transmissions were installed (or are being installed today) on Renault Logan:
- Classic "mechanics" with five steps.
- Automatic transmission with torque converter.
- Robotic "box" (since 2004).
Each of the devices has a number of features:
Manual transmission (manual transmission) Renault Logan is available in two versions JH1 and JH The number of steps is 5. Despite the different designations, both "mechanics" have an almost identical design. The difference is only in the volume of the clutch housing. The oil in the manual transmission is filled at the factory and does not require periodic replacement.
“According to the manufacturer, the resource of the lubricating composition is equal to the service life of the vehicle. Exceptions - the need to top up or replace in case of repair.
The drive part of the device consists of the following units:
- Speed selector (mounted on a ball joint).
- Drive rod control "box".
- Carter checkpoint.
- Backstage.
The main gear is made in the form of a pair of cylindrical gears, selected taking into account noise indicators. The torque is transmitted from the main gear to the differential, and then to the front wheels.
During the operation of Renault Logan with manual transmission, the following breakdowns are possible:
- Problems with the inclusion of speed or the difficulty of returning the selector to a neutral position. The reason may be a violation of the integrity of the speed selection fork, a lack of oil, or jamming of the shaft gears. In each of the situations, you can not do without a major overhaul of the checkpoint.
- During the movement, the shift knob jumps out of the set position. Probable causes are worn gears or forks. In the presence of such problems, it is also impossible to do without a major overhaul.
- There were strange sounds in the process of movement in the area of \u200b\u200bthe "box". The cause of the problem may be the wear of the shafts or bearings, the appearance of chips between the teeth of the gear.
Automatic transmission (AL4, DP0) was installed on Renault Logan cars until 2014. Unlike "mechanics", oil is filled for a limited period and requires periodic replacement. The automatic transmission entered serial production in 1999, and representatives of three companies - Renault, Peugeot and Citroen - acted as developers. The gearbox is designed for front-wheel drive cars with a 1.4-2.0 liter engine.
Advantages - simple design, low production cost and reliability. Also, the device provides special systems for locking the torque converter and selector knobs.
The automatic transmission has a heat exchanger designed to reduce the temperature of the oil. This is caused by the risk of overheating of the hydraulic unit (especially in summer).
According to the developers, when operating in a temperature regime of 75-90 degrees Celsius, the automatic transmission resource is almost endless. In turn, operation at critical low or high temperatures leads to aging of elements and a decrease in service life.
There is a Renault Logan automatic box and a number of problems that sometimes manifest themselves during operation:
- Emergency reset to third speed.
- Difficulties with cold switching.
- The appearance of errors on the ECU.
- Blows when transferring the selector to another gear.
- Poor quality of oil seals, due to which periodic oil leaks occur.
A robotic gearbox has been installed on Reno Logan since 2014. The reason for the transition was the problems associated with the previous version of the automatic "box". The peculiarity of the "robot" is the simplicity and clarity of the design. In fact, this is the same “mechanics”, but with a control unit attached to it, a servo and hydraulic drive.
“The cost of maintaining a manual transmission is commensurate with the repair of a mechanical “box”, which makes the robotic vehicle more profitable for the car owner.”
The average fuel consumption is lower than in an automatic transmission with a torque converter by 10-15%. If desired, the car is transferred to manual control.
The only drawback that motorists complain about is the presence of jerks in the process of switching gears.
Proper maintenance is a guarantee of durability
The resource of each of the Renault Logan checkpoints considered directly depends on the correct care. The following is important here:
- Regular maintenance.
- Timely replacement of oil and clutch elements (for manual transmission).
- Periodic cleaning and condition monitoring.
- Filling with original oil recommended by the manufacturer.
Transmission:
1 - shaft of the side gear of the differential;
2 - clutch housing;
3 - input shaft;
4 - dirt cover; 5 - gear shift mechanism;
6 - fork of the clutch release drive;
7 - holder of wire harnesses;
8 - bracket for the cable sheath of the clutch release drive;
9 - back cover;
10 - breather hose fitting;
11 - hole for the vehicle speed sensor;
12 - body of the inner hinge of the left wheel drive;
13 - reverse light switch;
14 - gearbox housing;
15 - oil filler plug
Two types of manual transmissions are installed on Renault Logan cars: with a 1.4 liter engine - JH1, with a 1.6 liter engine - JH3. The marking is on the bottom of the gearbox housing. By design, both gearboxes are identical and differ only in the size of the clutch housing. The gear ratios of both gearboxes are the same.
Gearbox - two-shaft, with five forward gears and one reverse gear, with synchronizers in all forward gears. It is structurally integrated with the differential and final drive.
The gearbox housing consists of three parts: the clutch housing, the gearbox housing and the rear gearbox housing cover. The clutch housing and gearbox housing are cast aluminum alloy, and the back cover is steel stamped. The clutch housing is attached to the gearbox housing with screws. When assembling, a gasoline-oil-resistant sealant-gasket is applied between them. The back cover is attached to the crankcase with three bolts.
The input shaft is made as a block of driving gears, which are in constant engagement with the driven gears of all forward gears. The gears of all forward gears are helical, and the reverse gears are spur gears. Gears of 1-4 gears are made integral with the input shaft, the gear of the fifth gear rotates freely on the shaft. A fifth gear synchronizer is installed at the rear end of the input shaft. The output shaft is hollow, oil is supplied through it under the driven gears. The driven gears and synchronizers of 1-2 and 3-4 gears are located on the shaft. The fifth gear is mounted on the shaft with splines. On the side of the clutch housing, the bearing of the secondary shaft is roller, and on the side of the cover, it is ball bearing. An oil sump is located under the roller bearing of the secondary shaft, directing the flow of oil into the shaft. All parts mounted on the secondary shaft are pulled together in a package with a bolt screwed into the end of the shaft from the side of the cover.
The final drive gear is pressed onto the differential box. Behind the driven gear, a tapered roller bearing is installed on the differential box. Between the driven gear and the bearing, an adjusting ring is installed, the selection of the thickness of which regulates the preload in the differential bearings.
On the other (right) side, the differential box is equipped with a vehicle speed sensor drive gear and a second tapered roller bearing.
The differential box has two satellites and two side gears. The satellites are mounted on an axle fixed in the differential box.
The right semi-axial gear of the differential is made integral with the splined shaft, on which the inner hinge of the right wheel drive is put on. An oil seal pressed into the socket of the clutch housing runs along the cylindrical surface of the shaft. The left semi-axial gear is made on the body of the inner hinge of the left wheel drive, and the body is installed in the gearbox socket and secured in it with a retaining ring. In order to avoid oil leakage from the gearbox, the connection of the inner joint of the left wheel drive with the gearbox housing is sealed with a rubber boot, which is attached to the gearbox housing with a metal holder. The other side of the cover is attached to the outer ring of the needle bearing mounted on the left wheel drive shaft. The needle bearing is made integral with the oil seal, which prevents oil leakage from the gearbox along the wheel drive shaft.
To prevent water ingress and reduce dust ingress into the gearbox cavity, its breather is placed in the upper part of the engine compartment. The breather is connected by a rubber hose to the plastic fitting of the gearbox.
control mechanism:
1 - bushing;
2 - lever lock;
3 - gear lever;
4 - lever handle;
5 - mechanism body
control rod:
1 - coupling bolt;
2 - clamp;
3 - nut;
4 - thrust;
5 - thrust finger
The gearbox control drive consists of a control mechanism, a control rod and a gear change mechanism. A ball joint is installed on the gear lever, which is inserted into the plastic housing of the control mechanism and secured with a retainer. A sleeve is welded to the lower end of the lever, to which the control rod is attached. The other end of the control rod is connected to the gearshift mechanism mounted on the gearbox.
The gearbox is factory-filled with gear oil designed to last the life of the vehicle. The oil level in the gearbox should be at the level of the lower edge of the filler hole. The filler hole is located in the gearbox housing, in front of the vehicle. The plastic filler plug is made in such a way that it can be unscrewed and wrapped by hand, without the use of any tool. The cork is sealed with a rubber ring. The drain hole is located on the bottom of the gearbox housing. The drain plug is sealed with a copper washer.
Renault Logan manual transmission is the main type of gearbox on cars of this model. Automatic transmission is less common, mainly in expensive trim levels. Maintenance of automation is more expensive, and it increases fuel consumption. But many motorists don't mind the extra cost. The serviceability and ride comfort are worth it.
Five steps forward and one back
Renault Logan is a people's car, affordable and economical to operate. It provides two types of front-wheel drive engines, 1.4 and 1.6 liters. Except for crankcase dimensions, their manual gearboxes (JH1 and JH3) are identical . They are not complex. The device is carefully thought out, and the gearshift mechanism is designed perfectly. The lever does not require significant effort and easily falls into the desired step.
The gear ratios of the gearbox are calculated and made for the dimensions and loads of the car, they are close to the average for this class.
The mechanical transmission drive consists of:
- shift lever on a ball bearing;
- manual transmission control drive rods;
- backstage;
- box crankcase.
Transmission oil is filled for the entire service life (300,000 km) under the lower edge of the filler hole. Crankcase volume 3.1 l, eye control, dipstick not provided. Some motorists consider this a design flaw. But in fact, a dipstick is not needed: just unscrew the plug to make it clear whether you need to add oil or not. Any smudges and stains under the car should alert. With trouble-free driving, the tightness of the crankcase is maintained. A low oil level is manifested by extraneous noise in the crankcase, which is impossible not to hear. Although the manufacturer does not require, many mechanics recommend changing the oil after 90,000 km. Waste oil is drained through a special drain hole. Then - flushing and filling. Thus, the life cycle of the manual transmission is extended. Unanimous opinion - 300,000 for Logan is not the limit.
The automatic gearbox is more complicated, its device is designed for 4 speeds. Its own oil, for automatic transmissions, it differs from mechanical transmission oils. It is also poured immediately for the entire period, but if a replacement is required, it is important not to forget that this should be the oil for an automatic transmission. What is poured into a mechanical box will not work and can damage the machine.
Problems and Solutions
The Renault Logan gearbox is structurally very reliable, but the world around us is not perfect. Driving is always a risk. Sometimes repairs are inevitable. There are tens of thousands of Renault owners in Russia, and they actively share their operating experience at various club forums.
From what worries motorists and mechanics, the following can be distinguished:
- The desired gear does not turn on, the lever handle does not return to its original position. Service immediately. There are dozens of reasons, and almost all threaten to destroy the device.
- Extraneous noise in the gearbox. Stop and check the oil in the crankcase. If the level is below the lower edge, then the problem is mechanical, service repair is required.
- Suddenly the lever is knocked out of gear. Damaged gears or worn gear grooves or selector fork. Get ready for a transmission overhaul.
- Oil leakage - check oil seals and seals, replace worn ones. The work is simple, within the power of a novice motorist. Don't forget to add oil. If smudges reappear, urgently go to the service, check if there is a crack in the crankcase.
- Rumbling sounds at idle, which disappear when the clutch is depressed. False alarm. Everything is in order with the manual transmission, this is a feature of the Logan release bearing on cars that came off the assembly line. If the sound is very unnerving, replacing the clutch fixes the problem.
When communicating on the forums and in the "garage brotherhood" you can hear about other shortcomings. How many heads - so many minds, how many cars - so many problems. In general, the opinion about Logan dominates, as a good, reliable car that does not cause unnecessary concern to the owner.
Living and driving will be easier
The automotive industry is moving forward, and Renault is with it. Technical innovations are always exciting, the industry lives up to expectations. We are enthusiastic about the Easy’R robotic gearbox, created by French manufacturers with the participation of German designers.
The same 5 forward gears, but increased operational reliability and fuel efficiency. Most of all, the scheme of the device will please inexperienced drivers in tight parking lots, as well as when driving on an icy road and on a steep slope. For this, the Winter and Hill Start Assist modes are provided (I will help you start up the hill).
The Easy'R gearbox is installed on the new Renault LOGAN, SANDERO and SANDERO Stepway. The owners of new products have already appreciated and given excellent reviews. On the way to the ideal, Renault is steadily moving forward.
