Transmission Diagnosis: What’s Wrong with My Transmission?
Today’s Automatic Transmissions use a variety of sensors on the engine and throughout the car, along with a computer system that control its functions. Most computer-controlled transmissions use a TCM (Transmission Control Module) however; some systems use a single computer for both the engine and transmission control. These are commonly referred to as an ECM (electronic Control Module).
It’s common today to have over a dozen separate control modules communicating through a network; all sharing information about the operation of the car. Because of this sophistication, there are a lot of sensors and control modules that play a role in transmission operation.
This means problems with your suspension, lighting system, or even something as innocuous as a malfunction in your radio can cause a problem with your transmission.
That’s why it’s important to have these systems check by a trained transmission technician anytime you think you might have a transmission problem. Many times it turns out not to be a transmission problem at all but something else in another system; something far less expensive than a rebuilt transmission.
So, you have a transmission that’s not shifting right? We will be happy to check your car’s computer systems and find out why.
