Frequently Asked Questions
What does ‘VIN Programmed’ actually mean for me?
It means this module is ready for installation right out of the box. We use your vehicle’s unique 17-digit Vehicle Identification Number (VIN) to load the exact software and calibrations your Pontiac G5 requires. This eliminates the need for any additional, and often costly, programming at a dealership or specialized shop.
Will this fix a 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 of the P0700, it’s crucial to have the specific transmission codes (e.g., P0751, P0756) read to confirm the issue is with the module or its related solenoids. In many cases, replacing a faulty TCM is the correct fix.
Is this difficult to install myself?
For most DIYers with basic tools, this is a straightforward job. On the Pontiac G5, the TCM is typically located on the driver’s side strut tower in the engine bay. The process involves disconnecting the battery, unplugging the electrical connectors, unbolting the old module, and installing the new one. It usually takes less than 30 minutes.
Do I need to send my old part back?
No, there is no core charge for this part. You can keep your old module, which saves you the time and hassle of packaging and shipping a return.
How do I know for sure that my TCM is the problem?
The most common indicators are erratic shifting, getting stuck in one gear, and specific diagnostic codes stored in the computer. If you are experiencing multiple electronic transmission symptoms simultaneously, the TCM is the most likely point of failure. This Pontiac G5 Transmission Control Module is designed to correct these exact electronic failures.
