Towing a vehicle with automatic transmission (automatic transmission) - a procedure that requires special care. Unlike a manual, where the clutch allows you to separate the engine and transmission, in an automatic the oil pump only works when the engine is running. This means that if you tow without following the rules, you risk damage the planetary gear or torque converter due to lack of lubrication.
In this article we will look at how to tow a car with automatic transmission. no consequences for the box: From gear mode selection to speed and distance limits. Let us separately dwell on the nuances for different types of machines - classic hydraulic, robotic (DSG, Powershift) and variators (CVT). You will also find a checklist for emergency towing and a compatibility table for drive types.
There is no point in arguing about whether it is possible to tow an automatic vehicle: it is possible, but strictly according to the manufacturer’s instructions. For example, Toyota and Honda allow towing in neutral for no more than 50 km at speeds up to 50 km/h, and BMW with box ZF 8HP - only with lifting the drive wheels. Ignoring these rules will result in repairs of 50,000 rubles.
1. Why towing is dangerous for automatic transmissions: technical risks
The main problem is no oil circulation in the box with the engine off. In a machine, oil performs three functions:
- 🔹 Lubrication rubbing parts (planetary gears, bearings).
- 🔹 Cooling torque converter and clutches.
- 🔹 Torque transmission in hydraulic systems.
When towing in neutral, only the output shaft and differential rotate, but the oil pump (which is driven by the crankshaft) does not work. As a result:
- 🚨 Overheating friction discs due to dry friction.
- 🚨 Badass gears in a planetary mechanism.
- 🚨 Bearing failure due to lack of lubrication.
Particularly vulnerable variators (CVT): Their belt and cones require constant lubrication. For example, in Nissan Qashqai with variator Jatco JF011E towing over a distance of more than 30 km without hanging the wheels is guaranteed to lead to belt slippage and accelerated wear.
⚠️ Attention: If your car has dry clutch robot (for example, VW DSG-7 DQ200), towing in neutral is strictly prohibited. In such boxes, the clutch opens only when the ignition is on, otherwise the driven disc will slip, destroying the friction layer.
2. Preparing your car for towing: step by step
Before hooking the cable, complete the following steps:
Make sure the engine is off and the key is in the ACC (or removed from the lock)
Check the oil level in the automatic transmission - if the level is low, towing is prohibited
Move the selector to position N (neutral)
Disable ESP/ASR (if there is a button, press and hold for 5 seconds)
Check the fastening of the towing eyes (on some models they are closed with plugs)
-->
If you are towing four wheel drive vehicle (for example, Subaru Forester or Audi Quattro), required hang one of the axes. Otherwise, the differentials and transfer case will rotate without lubrication, which will lead to them jamming. For front wheel drive vehicles (eg Hyundai Solaris) neutral is sufficient, but the speed should not exceed 40 km/h.
Important: on some models (for example, Mercedes-Benz with 7G-Tronic) to unlock the selector when the engine is off, it is required emergency hole under the hood. Its location is indicated in the manual. If you cannot move the lever to N, do not use force - contact a tow truck.

3. Speed and distance: critical limits
Manufacturers clearly regulate towing parameters for automatic transmissions. Exceeding these values leads to warranty disclaimer if the box breaks. Below is a summary table for popular brands:
| Make/Model | Max. speed (km/h) | Max. distance (km) | Notes |
|---|---|---|---|
| Toyota Corolla (U660E) | 50 | 50 | Neutral only, ignition ON |
| Honda CR-V (variator) | 40 | 30 | Stop for 5 minutes every 10 km |
| BMW 5 Series (ZF 8HP) | — | — | Towing prohibited, tow truck only |
| Ford Focus (Powershift DCT) | 30 | 20 | Only with suspended front axle |
| Nissan X-Trail (CVT Jatco) | 40 | 25 | After towing, check the oil for metal shavings. |
General rule: the more modern the box, the stricter the restrictions. For example, in old 4-speed automatic transmission (for example, Aisin AW55-50SN in Volvo S60) towing was allowed up to 80 km at 60 km/h, and in new 9-speed (ZF 9HP) - tow truck only.
⚠️ Attention: If you are towing a vehicle with Start-Stop system (for example, Mazda CX-5), be sure to disable it through the on-board computer menu. Otherwise, when stopping, the box will try to switch to P, blocking the wheels.
After towing over 10 km be sure to check the automatic transmission oil. If it turns black or has a metallic sheen, the box has been damaged. In this case:
- Do not start the engine.
- Call a tow truck for service.
- Point out to the technician the signs of overheating (burnt smell, chips on the dipstick).
4. Rope towing vs. tow truck: what to choose
The choice of method depends on the type of box and conditions:
When is a tow truck required?
A tow truck is necessary in 100% of cases for:
- Cars with robotic boxes (DSG, S-Tronic, EDC)
- Machines with all-wheel drive (if it is impossible to hang both axes)
- Auto with CVTs when towing more than 20 km
- Any automatic transmission when towing uphill (the load on the pump increases)
If you decide to tow by cable, follow the rules:
- 🔗 Use rigid coupling (not a cable!) for distances of more than 10 km - it eliminates jerks.
- 🚗 The towed vehicle must be lighter than a towing vehicle by at least 30%.
- 📏 The length of the cable is no more than 4 meters (for a flexible coupling) or 2 meters (for a rigid one).
- 🔄 Every 500 meters, stop for 1-2 minutes to cool the box.
When towing in hot weather (above +25°C) reduce the distance by 30%. For example, if the manufacturer allows 50 km, drive no more than 35 km. The temperature of the oil in the automatic transmission during towing increases 2-3 times faster than during normal driving.
If you are towing a car with an automatic transmission in severe frost (below –15°C), before starting to move, warm up the box with an external heat source (for example, a heat gun) for 10–15 minutes. Cold oil is viscous and does not reach the parts in the required volume.
5. Towing features for different types of automatic transmissions
Each type of automatic transmission has unique limitations:
5.1. Classic hydraulic automatic
The most “tolerant” type for towing. Examples: Aisin AW55-50SN (Volvo), GM 6L80 (Chevrolet Tahoe). Rules:
- 🔄 Selector in
N, ignition inON(to unlock the steering wheel and gearbox). - 📉 Speed up to 50 km/h, distance up to 80 km.
- ⚙️ After towing, check the oil level - leaks through the breather are possible.
5.2. CVT (CVT)
The most vulnerable type. Examples: Nissan Jatco, Toyota K311. Errors when towing will lead to belt slippage and its delamination.
- 🚫 Towing on a cable for more than 20 km is prohibited.
- 🔧 It is mandatory to check the oil for metal shavings after towing.
- 🔄 If you are towing Nissan or Mitsubishi with a CVT, stop for 3–5 minutes every 5 km.
5.3. Robotic gearbox (DSG, S-Tronic, EDC)
Towing is only possible with suspended drive wheels. Examples: VW DSG-7, Ford Powershift.
- 🚗 If it is impossible to hang the wheels, only a tow truck.
- 🔌 On some models (for example, BMW M DCT) you need to connect a diagnostic scanner to unlock the box.
For robotic boxes with wet clutch (for example, DSG-6 DQ250) towing in neutral is possible, but no more than 10 km at a speed of 30 km/h. However, the risk of clutch damage remains high - it is better to use a tow truck.
6. What not to do when towing an automatic transmission
Even small mistakes can result in costly repairs. Common prohibitions:
- 🚫 Towing at speeds above 50 km/h — leads to oil cavitation and destruction of bearings.
- 🚫 Coasting with the engine off (for example, downhill) - the pump does not work, the box remains without lubrication.
- 🚫 Using position
DorR— blocks the wheels and leads to breakdown of the planetary gear set. - 🚫 Towing with an empty tank — the fuel pump may overheat (on some models it is cooled by gasoline).
- 🚫 Sharp jerks of the cable — shock loads destroy friction clutches.
A separate taboo - towing a car with an automatic transmission with another car with an automatic transmission. Double load on the boxes of both cars increases the risk of overheating exponentially. If there is no alternative, follow:
- Speed no higher than 20 km/h.
- Distance no more than 5 km.
- Stops every 1–2 km.
⚠️ Attention: On vehicles with automatic braking system (for example, Toyota Safety Sense) towing with the ignition on can lead to spontaneous activation of the brakes. Before towing, turn off the system through the menu or remove the fuse (indicated in the manual).
7. What to do after towing: diagnosis and prevention
Even if the towing went without any visible problems, perform the following checks:
Check the oil level and condition (color, smell, presence of chips)
Test gear shifting on site (delays, jerks)
Check for errors using the OBD-2 scanner (codes P0730–P0799 indicate automatic transmission problems)
Drive 1–2 km with the air conditioning on (additional load will reveal slippage)
If you have any suspicions, contact us for diagnostics within 24 hours
-->
If symptoms appear after towing:
- 🔴 Jerks when switching — wear of the friction clutches is possible.
- 🔴 Rumble or grinding noise - damage to bearings.
- 🔴 Burning smell — overheating of the oil and torque converter.
- 🔴 Error "Transmission Hot" - critical overheating.
Stop driving immediately and call a tow truck. Further use will worsen the damage.
For prevention after towing:
- 🛢️ Change the automatic transmission oil and filter (even if the regulations do not fit).
- 🔧 Adapt the box (for example, for DSG or ZF adaptations need to be reset via diagnostic equipment).
- 📊 Reset errors via scanner (some, e.g.
P0700, may be false after towing).
FAQ: Frequently asked questions about towing an automatic transmission
Is it possible to tow a car with an automatic transmission on the highway (speed 90+ km/h)?
No. The speed limit for most automatic transmissions is 50 km/h. At a speed of 90 km/h, the oil in the box overheats in 5–10 minutes, which leads to the destruction of clutches and bearings. If you need to travel a long distance, use a tow truck or flatbed transportation.
What happens if you tow a car with an automatic transmission in the D or R?
This will lead to blocking of the output shaft of the box and breakdown of the planetary mechanism. In the best case, the lever will jam, in the worst, the gears will be destroyed, and the box will require major repairs (from 80,000 rubles). Always move the selector to N before towing.
Is it possible to tow a car with an automatic transmission in winter at -20°C?
It is possible, but with reservations: warm the box with an external heat source (for example, a heat gun) for 15 minutes. Cold oil thickens and does not reach the parts, which accelerates wear. Reduce speed to 30 km/h and distance to 10 km. After towing, change the oil immediately: at low temperatures, paraffin deposits form in it.
How to tow a four-wheel drive vehicle with an automatic transmission (for example, Toyota RAV4)?
Only with one axle hanging (front or rear). If you can’t hang it out, use a tow truck. In all-wheel drive vehicles, when towing, all differentials and the transfer case rotate, which without lubrication leads to their jamming. For example, in Subaru Outback With symmetrical all-wheel drive, towing on a cable even for 1 km can damage the center differential.
Do I need to turn on the ignition when towing an automatic transmission?
Yes, but only in position ACC or ON (without starting the engine). This unlocks the steering column and gearbox (on some models). However, on vehicles with electronic parking brake (for example, Volvo XC60) the ignition must be turned off, otherwise the brake may be activated spontaneously.
