Frequently Asked Questions
Do I need to program this module?
No. We handle the programming for you before shipment. Simply provide your vehicle’s VIN during checkout, and the module will arrive ready to install for true plug-and-play functionality.
What is a Transmission Control Module (TCM)?
The TCM is the electronic brain of your automatic transmission. It receives data from various sensors on the vehicle and uses that information to control when the transmission shifts gears, how firmly it shifts, and when to lock the torque converter. A failing TCM is a common cause of shifting problems.
Where is the TCM located on my 2006-2011 Impala?
On most Chevrolet Impala models from this generation, the T42 TCM is located in the engine bay, typically attached to or underneath the air cleaner housing. Always disconnect the battery before beginning removal and installation.
Will this fix a P0700 trouble code?
A P0700 code is a general fault code indicating that the TCM has detected a problem and has requested the check engine light be turned on. While this module can resolve the underlying issue causing the P0700, it’s important to have the vehicle scanned for other specific transmission codes (e.g., P0751, P0756) to confirm the TCM is the root cause.
What happens if I don’t replace a bad TCM?
Continuing to drive with a faulty TCM can lead to more severe and expensive mechanical damage to your transmission. Poor shifting can cause excessive wear on clutches and bands, and being stuck in limp mode can be a serious safety hazard.
