Frequently Asked Questions
Do I need to do any programming after installation?
No, the core engine and transmission programming is done for you. However, on most of these GM vehicles, you will need to perform a simple security relearn procedure, which can be done without special tools and typically takes 10-15 minutes. Instructions are readily available online, or your mechanic will be familiar with the process.
How do I provide my Vehicle Identification Number (VIN)?
After you complete your purchase, you can add your 17-digit VIN to the ‘notes’ section of your order. If you forget, we will contact you via email to request it before we can program and ship your module.
Will this fix my transmission shifting problems?
In many cases, yes. The PCM controls transmission line pressure and shift points. If the module is failing, it can cause a wide range of shifting issues. Replacing it with a correctly programmed unit is often the solution for these electronic transmission problems.
Is this a brand new part?
This is a professionally restored and tested OEM component. We use original factory hardware, which is often more robust than aftermarket alternatives, and ensure it’s functioning perfectly and loaded with the latest software for your vehicle.
My original part number is slightly different. Will this still work?
This module is a direct replacement for several part numbers, including 16263494 and 16265035. As long as your vehicle is on the compatibility list, our VIN programming will ensure it functions correctly, even if your original number differs.
