Is Your Savana 2500 Van Stuck in Limp Mode?
If your workhorse GMC Savana 2500 is suddenly shifting hard, refusing to shift, or stuck in a single gear, you know how frustrating it is. Every minute your van is down, you’re losing time and money. Before you assume the worstโa costly transmission rebuildโthe problem is very often the brain of the operation: the Transmission Control Module (TCM). In my 20+ years as a mechanic, I’ve seen countless GM vans and trucks with these exact symptoms, and a faulty TCM is one of the most common culprits.
From the Shop Floor: A Real-World Scenario
“A customer’s 2011 Savana 2500 came in last week on a tow truck. The driver said it felt like it got slammed into gear and then wouldn’t shift past 2nd. Another shop had quoted him over $3,000 for a transmission rebuild. I plugged in my scanner and immediately saw a P0752 code (Shift Solenoid ‘A’ Stuck On). Instead of just replacing the solenoid, I checked the TCM connector first. After seeing no issues there, I knew from experience that these T42 modules can fail internally, sending faulty signals. We installed one of our pre-programmed TCMs, and in under 30 minutes, the van was shifting perfectly. The customer saved thousands and was back on the job the same day.”

Plug-and-Play Installation: No Dealer Visit Required
You can get your van back on the road in under an hour. For the 2006-2014 Savana 2500 Transmission Control Module, the location is consistent and accessible.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts and to help reset the system.
- Locate the TCM: On your Savana van, the TCM is located in the engine compartment on the right-hand (passenger) side.
- Disconnect and Remove: Carefully unplug the electrical connectors. Use a small flathead screwdriver to gently release the locking tabs if needed. Then, unbolt the module from its mounting bracket.
- Install the New Module: Bolt the new, pre-programmed module into place and securely reconnect the electrical harnesses. You’ll hear a click as they lock in.
- Reconnect and Verify: 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. Take the vehicle for a test drive to confirm smooth shifting has been restored.
