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.
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? Make sure you check with the TrannyMan at Cloquet Automotive. He'll be happy to check your car’s computer systems and find out why.
