Is Your Work Van Sidelined with Transmission Problems?
If your 2006-2014 GMC Savana 3500 is your mobile office and tool carrier, you can’t afford downtime. When the transmission starts acting upโbanging into gear, refusing to shift, or throwing a check engine lightโit’s not just an inconvenience; it’s a threat to your business. In my 20+ years in the shop, I’ve seen countless work vans with these exact issues. More often than not, the problem isn’t a catastrophic mechanical failure but a faulty Transmission Control Module (TCM), the electronic brain in charge of your shifting.
This T42 TCM, part number 24235732, is the definitive solution, arriving pre-programmed to your van’s specific VIN. This means you can bypass the dealership entirely, saving you hundreds of dollars and days of lost work.
The Smart Fix: A Pre-Programmed Savana 3500 Transmission Module
Replacing a TCM used to be a two-step process: install the part, then tow the vehicle to a dealer for expensive programming. We eliminate that second step. By programming the module with the latest GM software updates before it ships, we ensure it’s a true plug-and-play part. It will communicate seamlessly with your Savana’s Engine Control Module (ECM) and other systems right out of the box.
From the Shop Floor: “A customer’s 2011 Savana 3500 came in last week with these exact symptomsโit was getting stuck in 3rd gear, and the check engine light was on with a P0751 code. He was convinced he needed a new transmission. Experience has taught me that on these workhorses, heat and vibration are brutal on electronics. Before condemning the transmission, we installed one of our VIN-programmed T42 modules. In less than 30 minutes, the van was shifting perfectly. We saved him a $3,000+ repair bill and got him back on the job the same day.”
Common Symptoms of a Failing T42 TCM:
- โ Harsh, abrupt, or erratic gear shifts.
- โ Vehicle is stuck in one gear (often called “limp mode”).
- โ Check Engine Light or Transmission Warning Light is illuminated.
- โ Diagnostic Trouble Codes (DTCs) like P0700, P0750-P0758, or other solenoid-related faults.
- โ Delayed engagement when shifting from Park to Drive or Reverse.
- โ Poor fuel economy and a feeling of lost power.
Plug-and-Play Installation: No Dealer Visit Required
You can have your Savana back in service in under an hour with basic hand tools. This is a straightforward repair for any DIYer or professional technician.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting work.
- Locate the TCM: On the 2006-2014 Savana 3500, the transmission module is located in the engine compartment on the right-hand (passenger) side.
- Disconnect and Remove: Carefully unplug the electrical connectors. Press the release tabs firmly. Then, unbolt the old module from its mounting bracket.
- Install the New Module: Bolt the new, pre-programmed module into place and securely reconnect the electrical harnesses. You should hear a click as they lock in.
- Final Steps: Reconnect the battery terminal. Start the vehicle and allow it to idle for a few minutes. If you have a basic scan tool, it’s good practice to clear any stored fault codes.
