Frequently Asked Questions
Will this TCM need to be programmed by a dealer?
No. This is the primary benefit of our service. We program the module to your vehicle’s specific VIN before shipping it to you. It arrives ready for a plug-and-play installation, requiring no further programming or dealership intervention.
How difficult is the installation on an Express van?
Installation is straightforward for someone with basic mechanical skills. On most Express and Savana vans, the TCM is located in the engine compartment on the right-hand (passenger) side. It typically involves disconnecting the battery, unplugging the electrical connectors, and unbolting the old module. The entire process can usually be completed in under 30 minutes.
Do I need to return my old TCM? Is there a core charge?
No, there is no core charge for this part. You can keep your old module, which saves you the hassle and cost of return shipping.
How can I be sure this is the correct part for my van?
This module is designed for 2006-2014 GM vehicles with a 4-speed automatic transmission. The best way to confirm is to match your vehicle’s year, make, and model to our fitment list. Providing your VIN during checkout ensures we program the correct software for your specific vehicle configuration.
What happens if I don’t replace a failing TCM?
Continuing to drive with a faulty TCM can lead to more severe issues. Poor shifting can cause premature wear on internal transmission components like clutches and bands, potentially leading to a complete mechanical failure and a much more expensive repair down the line.
