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.
Is it my Transmission Control Module or my ECM?
A bad battery, a bad alternator and other electrical problems can send inadequate voltage to you Transmission Control Module causing your engine/transmission or both to act crazy.
Can a Mercedes-Benz have a transmission failure?
Very few Mercedes-Benz cars have had complete transmission failure and require transmission replacement. We see these transmission fail in rare cases when water enters the transmission via the oil cooling lines or the radiator on cars equipped with Valeo radiators.
What happens when a cruise control sensor fails?
When the sensors fail to deliver accurate data to the onboard computer on your car, truck, or SUV, the powertrain control module (PCM) will send an error code to the vehicle’s ECU. As a safety precaution, the ECU will shut down the cruise control and render it inactive.
Can a car battery corrosion cause transmission problems?
Not only will this corrosion cause your battery issues, but it can also cause you transmission problems, leading to larger a transmission repair. You can clean the battery off yourself with a wire brush, however, it is smart to bring it in to a professional so you don’t cause any further problems by disconnecting the cables accidentally.

What is the purpose of a Transmission Control Module?
This module is basically a computer which communicates information to other computer systems within the vehicle. The purpose of the transmission control module is to help the automatic transmission choose the best gear to be in at any given time. That way, the driving performance and fuel economy will be at the optimal level.
How to check battery voltage in TCM module?
Connect the red lead of your voltmeter to each B+ (battery voltage) supply coming into the TCM module connector and the black lead of your voltmeter to a good ground (if not sure, battery negative always works). You should see a reading of battery voltage. Verify that you have good grounds as well.
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.
How much does it cost to replace a Transmission Control Module?
Replacement Cost. The replacement cost of a transmission control module will be anywhere from $500 to $900. You can expect the parts costs to be around $450 to $700 while the labor costs will be around $50 to $200.
