Frequently Asked Questions
How do I provide my VIN for programming?
After placing your order, you can add your 17-digit Vehicle Identification Number (VIN) to the order notes or send it to us via email with your order number. We cannot ship your part until we receive the VIN, as this step is essential for the plug-and-play functionality.
Is this part difficult to install?
For someone with basic mechanical skills, the installation is straightforward. The TCM is typically located in the engine bay and is accessible with common hand tools. On the 2006-2011 Impala, it’s found in the lower air cleaner housing. The entire process usually takes less than 30 minutes. Always disconnect the battery before starting.
Will this fix a P0700 trouble code?
A P0700 is a generic code indicating the TCM has detected a fault. In many cases, a failing TCM is the root cause, and replacing it with our VIN programmed T42 TCM will resolve the issue. However, you should always diagnose any other specific codes (e.g., solenoid codes) that appear alongside the P0700.
Do I need to return my old part?
No, there is no core charge for this part. You can keep, recycle, or dispose of your old module without the hassle of sending it back.
What happens if I install a TCM that isn’t programmed?
An unprogrammed TCM will not communicate correctly with your vehicle’s other computers, such as the Engine Control Module (ECM). This will result in the vehicle not starting, not shifting correctly, or displaying multiple error codes. Our pre-programming service prevents all of these issues.
