Frequently Asked Questions
What is VIN programming and why is it important?
VIN programming loads your vehicle’s specific software and settings onto the TCM. This ensures the module communicates correctly with the engine and other systems, controlling shift points, line pressure, and torque converter lockup precisely as the manufacturer intended. Without it, the vehicle may not start or shift properly.
Do I need any special tools to install this TCM?
Basic hand tools, such as a socket set, are typically all that is required to physically replace the module. After installation, a standard OBD2 scanner is recommended to clear any lingering fault codes from the vehicle’s memory.
Will this fix my P0700 transmission fault 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 a faulty TCM itself can cause a P0700, this code often points to another specific transmission code stored in the TCM. This replacement module will resolve the P0700 if the TCM is the root cause of the failure.
Is there a core charge for my old part?
No, there is no core charge associated with this part. You are not required to send your old, non-working module back to us, saving you time and shipping costs.
How do I confirm this part fits my vehicle?
This module fits a wide range of 2006-2014 GM vehicles, including the 2006-2009 Chevrolet Uplander. The best way to confirm fitment is to match the part number 24235732 or one of the interchangeable numbers listed in the description to the part number on your existing module.
