Is Your Savana Van Shifting Poorly? Get Back on the Road Fast.
For a contractor or business owner, a work van isn’t just a vehicle—it’s a critical tool. When your 2006-2014 GMC Savana 2500 starts experiencing harsh shifting, getting stuck in gear, or throwing transmission codes, it means downtime and lost revenue. This VIN-programmed T42 Transmission Control Module (TCM) is the definitive solution to get your van’s transmission operating like new, eliminating the need for expensive dealership programming and getting you back to work with confidence.
Common Symptoms & Your Solution
A failing TCM can cause a host of frustrating and debilitating issues. If you’re noticing any of the following, it’s a clear sign that your transmission’s brain is failing. This module is engineered to resolve these exact problems:
- Harsh, Erratic, or Delayed Shifting: Clunky gear changes or a noticeable lag when the transmission should be shifting.
- Stuck in “Limp Mode”: The vehicle refuses to shift out of a single gear (usually 2nd or 3rd) to protect the transmission from further damage.
- Check Engine Light & Transmission Warnings: Active trouble codes on your scanner, especially P0700 (Transmission Control System Malfunction) or various solenoid-specific codes (e.g., P0750, P0751).
- Failure to Shift: The transmission won’t upshift or downshift as engine RPMs change.
- Poor Fuel Economy & Overheating: Inefficient shifting and torque converter lockup issues can cause the engine to work harder and the transmission to run hot.

Frequently Asked Questions
Will this part need to be programmed by a dealer?
No. This Transmission Control Module comes pre-programmed to your vehicle’s specific VIN. It is ready for installation right out of the box, saving you the time and expense of a dealership visit.
How do I know if my TCM is the problem?
Common signs of a failing TCM include erratic or harsh shifting, the vehicle being stuck in limp mode (one gear), a lit check engine light with transmission codes (like P0700), and delayed gear engagement. A professional diagnosis is always recommended, but these symptoms point strongly to the TCM.
Where is the TCM located on my Savana van?
On most 2006-2014 GMC Savana and Chevrolet Express vans, the TCM is located in the engine compartment on the right-hand (passenger) side. Always disconnect the vehicle’s battery before starting the replacement.
What is the difference between a TCM and a PCM?
The TCM (Transmission Control Module) specifically manages the automatic transmission’s functions. The PCM (Powertrain Control Module) is a more integrated computer that typically controls both the engine and transmission functions in a single unit. Your vehicle’s design determines which component it uses.
Is there a core charge for this part?
No, there is no core charge required for this module. You can keep your old part without any hassle or need to return it.
