Frequently Asked Questions
What does a Transmission Control Module (TCM) do?
The TCM acts as the brain for your automatic transmission. It uses data from various sensors on the engine and transmission to control shift solenoids, manage fluid pressure, and determine the optimal gear for any driving condition, ensuring smooth and efficient operation.
Is this part difficult to install on my Buick Rainier?
No, this is a very DIY-friendly repair. The TCM on a 2006-2007 Rainier is typically located in the engine compartment. The process involves disconnecting the battery, unplugging the electrical connectors from the old module, unbolting it, and installing the new one in its place. Since our module is pre-programmed, no further steps are required.
Will I need any special tools for programming?
Absolutely not. The main benefit of our service is that we handle all the programming before the part is shipped to you. Your programmed T42 TCM 24252114 is ready for installation immediately upon arrival, requiring no special scan tools or software.
What happens if I continue driving with a bad TCM?
Continuing to drive with a failing TCM can lead to more severe and expensive problems. Poor shifting can cause excessive mechanical wear on clutches and bands inside the transmission, potentially leading to a complete transmission failure that requires a costly rebuild or replacement.
Do I need to return my old part (core)?
No, there is no core charge or requirement to return your old module. You can dispose of your old part at your convenience, making the repair process simpler and faster.
