Every car has to transmit the power that is produced in the engine to its wheels. This power has to be there to drive the car at high speeds. At times you need to climb hills at slow speeds. This change in the transmittance of power to the wheels is done by the transmission of a car. Transmission is controlled by the transmission control module. It is located on the rear side of the engine.

Gear changes are made by the transmission control module according to the data it receives from the engine. Depending on the signals it receives from sensors it will send the signals to the lock up clutch to make the necessary changes on transmission. Lock up clutch is the mechanism that helps regulate the use of fuel and the production of power to maintain efficiency.

The computerized module for transmission is able to remember data in its memory and use them to adjust the gear shifting according to the terrain the car is being driven. It works in unison with the engine to bring in the best advantage on engine efficiency and fuel saving. It is essential for the transmission control unit to work perfectly if the vehicle is to be used in the normal way. In case it is defective, you need to know the symptoms of a defective control transmission control module.

One of the ways to know a defective transmission unit is to notice if there is a delay in acceleration when you press the accelerator pedal. If there is a delay, it is a good idea to get your transmission system examined. Another symptom is that when you shift the gear selector to drive position your car will sound as if it is still in the neutral. Once you get any one of these symptoms or both, it is a good idea to get your car examined by a trained technician.

When you take your car for inspection, the technician will use a computer and will do the trouble shooting. In case your transmission control module is defective, you need to replace it. The replacement module could be bought in your local motor spare parts shops or with the dealer of your make. However, the easiest and the cheapest is to buy it from an online store.
