A car equipped with an automatic gearbox or a variator will not surprise anyone today.
Many drivers choose an automatic because of the convenience of driving, especially in urban areas with constant traffic jams. Despite such a wide distribution, not all drivers have even a basic understanding of correct operation these types of transmissions.
Can I tow a trailer in a car with automatic transmission?
Transporting a trailer by car is, in fact, one of the varieties of towing. Automatic transmission, subject to short towing, does not experience any overloads: increased heat generation reaches a critical level only if the transmission cooling radiator is too clogged with wear products, which significantly reduces the efficiency of the entire system.
Despite this, drivers of cars with a gun should remember that prolonged towing can lead to overheating and failure of the automatic transmission.
Essentially, transporting a trailer in a vehicle with automatic transmission it is possible, but it is desirable to acquire an additional cooling radiator in advance, and to carry out the towing process in overdrive mode and in ranges 2-3. Overdrive should not be used.
The only restrictions when towing a trailer is the weight of the trailer:
1. Up to 450 kg, while the trailer does not have a brake system;
2. Up to 800 kg with a brake system.
When purchasing a trailer for a car with automatic transmission, you should consider a few nuances:
Purchase of a trailer control system. Specifications and the features of such systems can be obtained from the trailer manufacturer;
It is impossible to tow cars or trailers on cars with automatic transmission for the first 2 thousand kilometers until the full run-in engine. Otherwise, transporting a trailer may cause serious damage both transmission and engine of a car;
Before towing, it is advisable to consult with official dealer machines and find out if a purchase is required special equipment- belts and other things;
The speed of movement should not exceed 100 km / h;
On steep climbs exceed the speed of more than 70 km / h or the established mode should not be.
Is it possible to drive with a trailer on a car with a CVT?
Recently, automatic transmissions have been replacing automatic transmissions. Distinctive feature such a transmission is a stepless change of torque. Simply put, the driver does not need to shift gears on his own. In addition, noticeable jerks when switching, characteristic of automatic transmissions, disappear.
Despite all the advantages of the CVT, it is even more demanding in operation than the automatic. Towing other cars or transporting trailers on such a transmission is highly undesirable: it not only increases the load on the box, but also leads to its rapid wear. The maximum that is allowed by manufacturers is the transportation of trailers, whose weight with a load does not exceed one ton.
Besides, the variator is an amateur good roads And mild conditions A: It is not recommended to use it on rough terrain. Despite the fact that many SUVs and crossovers are equipped with CVT transmissions and belong to the category of cars off-road, you should not count on the latter at a difficult moment: they are unlikely to help get out of a huge puddle in the middle of the field.
Accordingly, they are unlikely to transport a trailer, often used with just such car models.
However, it is possible to transport a trailer by car with a CVT, but with extreme caution and observing certain rules and nuances. Towing can be carried out either on a flexible or on a rigid hitch in the neutral position of the selector and with running engine.
If at least one condition is not met, then you can tow a trailer or other car only by the method partial loading. Otherwise, the owner of a car with a CVT will only be helped by a tow truck or freight car.
Is a trailer required?
To register a trailer and obtain documents for it, you must contact the traffic police department and submit an appropriate application. The trailer is registered at the place of residence of the owner of the vehicle within five days from the date of its purchase. After submitting the application, the license plate, year of manufacture, color of the sides and other characteristics are checked.
The make and model specified in the TCP, body number, frame number, an identification number must match exactly. The duty is paid only after the inspector witnesses such an inspection.
To register a trailer with the traffic police, you must submit the following documents to employees:
Statement according to which the trailer has passed a full inspection;
Contract of sale;
Passport of the owner of the vehicle;
Vehicle passport;
Receipt for payment of the fee.
After all the documents are checked, the trailer will be registered, and a corresponding mark will appear in the TCP.
Trailer towing car with automatic transmission. Features of driving with an automatic car trailer
automatic transmission tug
The automatic transmission is designed to operate the car in a fairly narrow range of its weight, maneuverability and road conditions. The trailer for her is an unplanned load that disrupts the operation of the torque converter.
Until recently, this question was of interest only to owners of foreign cars, since domestic Cars were not produced with automatic transmission. But since June 2012 started production Lada Granta with "automatic" type JATCO. It is planned to produce 10,000 cars in the past and 70,000 in the current year, 2013. The same automatic transmission will be installed on Lada Kalina. The undoubted convenience of automation turns into a complication of driving with an additional load.
Is it possible to tow a trailer
car with automatic transmission?
Manufacturer Russian cars equipped with automatic transmission, reminds that an increase in load causes increased heat transfer in the torque converter. Its overheating will cause an automatic transmission failure.
If a constant and long-term operation road trains with an "automatic", it is desirable to equip the transmission system with an additional radiator.
It is highly undesirable to tow a trailer in overdrive. It is safer for the vehicle and trailer to use only ranges "3" or "2".
Driving foreign cars with a trailer and automatic transmission
Similar driving features are described in the instructions on Volvo cars or Mitsubishi. Regardless of the make of the car, when driving uphill, do not press the accelerator sharply to stop the car, it is recommended to use only the brakes.
Prolonged operation of the engine with more than 4500 rpm is unacceptable.

Operation of a car with automatic transmission significantly limits the range allowable weight cargo, conditions of movement and opportunities for maneuver on the track. Towing trailers - an additional load on the box that violates the torque converter operation mode - leads to an increase in its heat transfer, which is fraught with a breakdown of the "machine".
But you can drive a trailer on the machine: overheating is likely only at high constant loads, system blockages and not enough oils. To use a passenger car as a towing vehicle permanently, it is recommended to equip the transmission with an additional radiator. The advice is especially relevant for owners passenger cars mobiles small permitted weight: in the process of towing, tightness, jerks occur, which will lead to an increased load on friction discs, their erasure and even the breakdown of the entire system. Powerful, massive SUVs are more suitable for regular driving with trailer equipment.
Basic rules for driving with a trailer on automatic transmission
Manufacturers of cars with an automatic gearbox describe in detail the rules for preparing a car for driving with trailers. It is strongly not recommended to drive with a trailer on a machine for the first 2 thousand kilometers (during this period, the car goes through a break-in period, and ignoring the requirement is fraught with damage to the engine and transmission). It is also worth equipping a car system dynamic stabilization trailer, which automatically reduces engine power and selectively slows down the car and trailed equipment until the yaw is eliminated.
For passenger cars, it is acceptable to tow trailers up to 450 kg, not equipped with brakes, and models up to 800 kg with braking system. In order to regularly tow a trailer on the machine, carefully monitor the level gear oil, the consumption of which will increase by 1.5 - 2 times.
Trailer + automatic transmission: how to combine?
Various forums for motorists are full of statements: automatic transmission gears and trailers are not compatible! But accelerated wear transmission due to increased load can be avoided by observing following rules movements:
- you can carry a trailer on an automatic box at a moderate speed not exceeding 100 km / h;
- do not exceed limit permissible loads specified in the manual for the car (it is strictly forbidden to tow loads whose mass is equal to or exceeds the mass of the vehicle);
- translate the box "automatic" into manual mode for towing trailers ( automatic switching under load are undesirable).
Vehicles equipped with the "L" (Low) driving mode are suitable for towing trailers. - downshift used when driving on ice, steep slopes and rise.
Important features of driving on the "machine"
The trailer has a negative effect on the gearbox: increased loads that are not provided for by the transmission design lead to overheating, frequent replacement Supplies. Avoiding the deplorable consequences of such exploitation is easy - just reduce the frequency of trips with trailers. If you need to regularly tow loads, keep an eye on the main parameters of movement: speed and speed. Continuous operation of the motor with a speed exceeding 4.5 thousand / min is strictly prohibited. Fast towing is prohibited.
Summarizing
The answer to the question of whether it is possible to drag a trailer on the machine lies in the instruction manual specific vehicle. Drive with trailed equipment on a compact urban hatchback with a 1.6 liter engine and up to 110 hp. not recommended, but acceptable for short trips and transportation of light loads (feel free to bring potatoes from the dacha, following the rules described).
But also on powerful SUVs do not accelerate too much, and on long climbs, keep the speed below 70 km / h. Suitable ranges for driving with trailers are "2" or "3". But before the trip, read the instructions: it indicates the recommended models of trailer equipment, additional systems necessary for its towing, as well as weight restrictions for models with and without brakes (when operating passenger cars, they are about 1.5 and 0.5 tons, respectively).
