Restore Your Van’s Drivability and Reliability
If your 2006-2014 GMC Savana 3500 is suffering from transmission problems like harsh shifting, delayed gear engagement, or is stuck in limp mode, a failing Transmission Control Module (TCM) is the most likely culprit. As the electronic brain of your automatic transmission, the T42 TCM governs every shift point and torque converter operation. A faulty one can cripple your work van, costing you time and money. This replacement module, part number 24235753, is the definitive solution, arriving pre-programmed to your vehicle’s VIN for a true plug-and-play fix.
From the Diagnostic Bay
I’ve seen countless work vans, especially Savana and Express models, come into my shop with complaints of unpredictable shifting. A customer last month had a 2011 Savana 3500 that would intermittently refuse to shift out of 2nd gear, especially on hot days. He’d already replaced a solenoid with no luck. A quick scan showed a generic P0700 code. Experience pointed me straight to the TCM. Heat soak and vibration are the biggest enemies of these modules. We installed one of our VIN-programmed units, and the van was back on the road in under an hour, shifting perfectly. This isn’t just a part; it’s a fast, reliable solution to a very common problem.
Is Your Savana Van Exhibiting These Transmission Problems?
A failing TCM will give you clear warning signs. If you’re experiencing any of the following, it’s time to consider a replacement 2006-2014 Savana 3500 TCM to avoid further damage to your transmission.
- ✔ Sudden, harsh, or banging shifts between gears.
- ✔ The vehicle feels stuck in one gear (often called “limp mode”).
- ✔ Check Engine Light or Transmission Warning Light is on with codes like P0700, P0750, or other solenoid-related DTCs.
- ✔ Hesitation or delay when shifting from Park to Drive or Reverse.
- ✔ Poor acceleration and a noticeable drop in fuel economy.
- ✔ Complete loss of communication with the transmission module.
Your 30-Minute Path to a Smooth-Shifting Van
One of the best features of this module is its simple installation. You don’t need a professional lift or complex tools. For your Savana van, the process is straightforward.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- Locate the Module: On the Savana 3500, the TCM is conveniently located in the engine compartment on the right-hand (passenger) side.
- Disconnect and Remove: Carefully unplug the electrical connectors. Note the tab locations to avoid damage. Then, unbolt the old module from its mounting bracket.
- Install the New TCM: Mount the new module securely onto the bracket and plug in the electrical connectors until they click firmly into place.
- Reconnect and Verify: Reconnect the battery terminal. Start the vehicle and allow it to idle for a moment. The pre-programmed module will handle the rest. We recommend clearing any old codes with a basic scan tool for a clean slate.

What exactly does ‘VIN Programmed’ mean for my Savana?
What exactly does ‘VIN Programmed’ mean for my Savana?
It means we load your vehicle’s specific Vehicle Identification Number (VIN) and the latest GM software onto the module before we ship it. This ensures it communicates perfectly with your van’s engine and transmission right out of the box, eliminating the need for a costly programming session at a dealership.
Is this a difficult part for a DIYer to install?
Not at all. For the Savana, the location in the engine bay is accessible, and the job only requires basic hand tools. The entire process typically takes less than 30 minutes, making it a great DIY project to save on labor costs.
Will this fix a P0700 trouble code?
A P0700 code is a general fault code indicating the TCM has detected a problem. While it doesn’t pinpoint the TCM itself, a failing TCM is a very common cause. Replacing a faulty module with our programmed 2006-2014 Savana 3500 TCM often resolves the root cause of the P0700 and any related specific codes.
Is there a core charge for my old part?
No, there is no core charge. You can keep your old module or dispose of it without the hassle of shipping it back to us, saving you time and money.
