Frequently Asked Questions
What does a transmission control module do?
The TCM acts as the brain for your automatic transmission. It uses data from various sensors on the vehicle to control when the transmission shifts gears, ensuring smooth operation, optimal performance, and fuel efficiency.
Is this part difficult to install?
For the 2006-2007 Rendezvous, the TCM is located inside the air cleaner box, making it very accessible. With basic hand tools, most DIY mechanics can complete the installation in under 30 minutes. Simply disconnect the battery, remove the air cleaner assembly, unplug the old module, and install the new one.
Will this TCM fix my P0700 trouble code?
A P0700 code is a general fault code indicating the TCM has detected a problem. While this module often resolves the root cause, it’s essential to have the vehicle scanned for any other specific codes (like solenoid or sensor codes) to confirm the diagnosis. In many cases, a faulty TCM is the primary issue.
Do I need to get this module programmed by a dealer?
No. The main benefit of our service is that this 2006-2007 Buick Rendezvous transmission control module comes fully pre-programmed to your vehicle’s VIN. It is ready for installation immediately upon arrival, saving you time and money.
What happens if I don’t replace a bad TCM?
Continuing to drive with a failing TCM can lead to more severe and expensive transmission damage. Poor shifting can cause excessive wear on internal components like clutches and bands, eventually leading to a complete transmission failure that requires a costly rebuild or replacement.
Is there a core charge for my old part?
No, there is no core charge. You are not required to send your old module back to us, which simplifies the process for you.
