What is a transmission computer?
A transmission control module is an electronic mechanism that collects data and processes signals within your transmission in order to regulate the transmission’s gear shifting. Without this mechanism, your transmission wouldn’t be able to shift gears effectively and consistently.
Can computer cause transmission problems?
Computers And Sensors A major cause of transmission problems is when the computer system is sending incorrect signals due to a faulty sensor. Another common problem with computerized transmissions is when the transmission does not react to the command because of a bad connection or defective solenoid pack.
What to do if your transmission control module is bad?
It’s important to understand though that if you are having troubles with your transmission, it’s not recommended that you blame it on your vehicle’s computer right away. You should always try to perform an ECM reset first before ruling out its a bad transmission control module.
What does it mean when your transmission is not working?
Your automatic transmission uses input and output speed sensors to determine whether your transmission is in the gear that the transmission control module (TCM) wants it to be in. If you see this code, it means that the TCM isn’t correctly calculating the shift pattern.
What to do if your transmission is acting up?
A simple check to make sure your transmission fluid levels are okay could save you a lot of headaches. Other problems that can cause your transmission to act up can usually be identified with a few diagnostic tests.
What does the Transmission Control Module processor do?
The TCM transmission module processor helps understand various signals transmitted by the drivetrain’s engine control module (ECM), and outputs signals to control a vehicle’s speed, shifting, and regulate the temperature inside the transmission.
