The key to a successful repair isn’t just replacing the partโit’s ensuring the replacement is correctly programmed. An unprogrammed module is just a paperweight. Our VIN programming service syncs the module to your van’s specific configuration before it even leaves our facility. This ensures all systems communicate correctly, from engine RPM to wheel speed, giving you a repair that’s not just fast, but done right the first time.
Don’t let a faulty TCM disrupt your work schedule. By choosing our pre-programmed 2006-2014 Savana 2500 Transmission Control Module, you’re investing in a reliable solution that gets you back on the road and back to business quickly and efficiently.
Frequently Asked Questions
What does a Transmission Control Module do on my Savana?
The TCM acts as the brain for your automatic transmission. It receives data from various sensors on the engine and vehicle, and uses that information to control exactly when and how the transmission shifts gears, ensuring optimal performance, fuel economy, and durability.
Is this part difficult to install?
For someone with basic mechanical skills, installation is straightforward. On most Savana vans, the TCM is located in the engine compartment on the right-hand side. The process involves disconnecting the battery, unplugging the electrical connectors, unbolting the old module, and installing the new one. It typically takes under 30 minutes.
How does the VIN programming process work?
During checkout, you provide us with your vehicle’s 17-digit VIN. We use this number to load the latest GM-certified software and calibrations specific to your exact van onto the module. This ensures it works seamlessly with your vehicle’s systems right out of the box.
Will this fix my specific transmission problem?
This module is the definitive solution for issues directly caused by a failing TCM, such as the symptoms listed above (erratic shifting, DTCs, limp mode). If your transmission has internal mechanical damage, this part will not fix that. We always recommend proper diagnosis before ordering.
Do I need to send my old part back?
No, there is no core charge for this part. You can keep or dispose of your old module, making the repair process simpler and more convenient for you.
