How to prevent the transmission from damage

- Regularly check your parking space for leaks. Doesn't matter, is it the engine oil leak, power steering fluid or transmission fluid; if you discover any, get it fixed before it caused something serious.
- Once in a while check the transmission fluid level and condition. Not all cars however have the automatic transmission dipstick, in some cars, for example, in late Volkswagen models, the transmission fluid can only be checked by the dealer. Consult with your owner's manual for details. If the transmission fluid level is too low, there is a leak somewhere that needs to be fixed.
- Change the fluid as often as it said in your owner's manual or when it becomes too dark (rather brown than red) or dirty.
Also, keep in mind that an automatic transmission can not be drained completely - there is always some transmission fluid left inside the transmission (the torque converter, in the valve body, etc.) which means you only can change about %60 of the fluid at once. This is one more reason to change it more often.
- Use only the same type of transmission fluid as specified in the owner's manual or on the dipstick. Many newer vehicles are very sensitive to fluid type. For example, an Owner's Manual for 2008 Honda Civic says "Using transmission fluid other than Honda Genuine ATF-Z1 may cause deterioration in transmission operation and durability, and could result in damage to the transmission".
- Never shift to the Reverse or Park until the car comes to a complete stop.
- Never shift from the Park to other gears when engine rpm is higher than normal idle.
- In many cars, the automatic transmission can be damaged if towing with the drive wheels on the road. Check your owner's manual for the proper way of towing your car.
