An Expert’s Note on Programming
A common mistake we see is installing a used TCM without proper programming. A TCM is the dedicated computer for your transmission; it’s not a one-size-fits-all part. It must be loaded with the specific software and calibrations for your vehicle’s unique engine, tire size, and gear ratios. Our VIN-programming service ensures this critical step is done correctly before the part ever leaves our facility, saving you from diagnostic headaches, return trips to the shop, and potential damage to your transmission.
This Programmed 2005 Buick LaCrosse TCM is your most effective path to resolving frustrating transmission issues and restoring the integrity of your vehicle. Place your order, provide your VIN, and get ready to install a part that works correctly the first time.
Frequently Asked Questions
Do I need to have this part programmed by a dealer?
No. The main benefit of our service is that we handle all the programming for you before we ship the part. It will arrive at your door flashed with the latest GM software and calibrated specifically to your vehicle’s VIN, making it ready for installation.
How do I provide my VIN number?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We will provide clear instructions on how to do this. We cannot ship your part until we receive and validate your VIN.
Is this a difficult part to install?
For someone with moderate mechanical experience, this is a straightforward installation. The TCM is typically located in the engine bay (often under the air cleaner housing) and is a direct bolt-in replacement. After installation, a transmission relearn procedure may be required, which can often be done by following a specific driving cycle. We always recommend consulting a service manual for your specific model.
Will this fix my check engine light?
If your check engine light is on due to diagnostic trouble codes related to the TCM, then yes, this part will resolve the issue. After installing the new module, you should use a scan tool to clear any existing codes from your vehicle’s computer.
What if my original part number is not on your list?
The part numbers listed are the most common, but there can be others. The most important factor is your vehicle’s VIN. As long as your vehicle is on the compatibility list, we can program this module to work perfectly. If you have any doubts, please contact us with your VIN before ordering.
