TRANSMISSION CONTROL MODULE
Transmission Control Module : This is a computer module used to control an automatic or cvt transmission. The transmission control module is vehicle specific and most will require special computer programming to sync it up with the vehicle. The transmission control module has many different functions and circuits to read many different inputs from various sensors, computing the shift pattern and performing specific outputs to achieve the desired shift results. Many transmission control modules can calculate the and accurately adjust the shift timing for the car, truck, van or suv.
A transmission control module can show signs of problems in many different ways. Transmission control module problems may include hard codes not correctible by just replacing a sensor, internal ram or checksum codes, the desired output is requested my the transmission control module however it is not sending the signal out of the transmission control module or no shifting of speeds. It takes special diagnostic skills and computer equipment to properly diagnose a faulty transmission control module. Computer programming on a transmission control module usually needs a factory scan tool.
