Frequently Asked Questions
Do I need to take my car to a dealer after installing this part?
No. The primary benefit of this module is that it comes pre-programmed to your vehicle’s VIN. This eliminates the need for any additional programming or setup at a dealership, saving you time and money.
Where is the TCM located on a 2006-2011 Chevy Impala?
On this specific model, the Transmission Control Module is typically found inside the lower air cleaner housing in the engine bay. It’s a straightforward installation for a DIY mechanic or any professional technician.
Will this fix a P0700 trouble code?
A P0700 code is a general transmission fault code, indicating that the TCM has detected a problem. While this module often resolves the root cause of a P0700, it’s always best to have the specific secondary codes read by a scanner to confirm the diagnosis. In many cases, a faulty TCM is the culprit.
Is any special tool required for installation?
Basic hand tools are all that’s required for the physical installation. We recommend disconnecting the battery before you begin. After installation, you may need a basic OBD2 scan tool to clear any stored fault codes from the vehicle’s memory.
How do I provide my VIN for programming?
You will typically be prompted to enter your vehicle’s 17-digit VIN during the checkout process. Please double-check it for accuracy to ensure perfect programming for your Impala.
