Is Your Saturn Vue Shifting Erratically?
If you’re dealing with harsh shifting, delayed gear engagement, or your 2007-2010 Saturn Vue is stuck in limp mode, a failing Transmission Control Module (TCM) is the most likely culprit. The TCM is the electronic brain of your automatic transmission, responsible for orchestrating every gear change and ensuring smooth, efficient operation. When it fails, it can cause a cascade of problems, from annoying shifting issues to a complete inability to drive. This genuine OEM-quality T42 TCM, service number 24239926, is the definitive solution to restore your vehicle’s transmission performance and get you back on the road with confidence.
From the Diagnostic Bay
We had a 2008 Saturn Vue come into the shop that the owner was about to give up on. The vehicle would randomly refuse to shift out of 2nd gear, and the check engine light was always on with a P0700 code. Another shop had quoted them thousands for a transmission rebuild. We hooked up our scanner and saw communication errors with the TCM. Instead of a costly mechanical repair, we installed a VIN-programmed T42 module. After a 20-minute installation and clearing the codes, the Vue drove like it was brand new. The customer was thrilled to have their vehicle fixed for a fraction of the cost, highlighting how critical a properly functioning 2007-2010 Vue TCM is to an accurate diagnosis.
The Plug-and-Play Solution for Your 2007-2010 Vue TCM
The biggest hurdle in replacing modern vehicle electronics is the need for expensive dealership programming. We eliminate that step entirely. Each T42 TCM is expertly programmed to your vehicle’s specific Vehicle Identification Number (VIN) before it ships. This ensures that it communicates flawlessly with your Vue’s other computer systems, like the Engine Control Module (ECM), right out of the box. There are no extra trips to the mechanic or dealership required. This is a true DIY-friendly, plug-and-play repair that saves you time and money.
Symptoms of a Failing Saturn Vue TCM
- ✔️ Harsh or Erratic Shifting: Experiencing sudden, jerky shifts or banging into gear.
- ✔️ Stuck in Limp Mode: The transmission will not shift past 2nd or 3rd gear as a protective measure.
- ✔️ Check Engine & Transmission Lights: Illumination of warning lights on your dash, often with DTCs like P0700 (Transmission Control System Malfunction) or various solenoid codes (P0750, P0751, etc.).
- ✔️ Delayed Engagement: A noticeable pause when shifting from Park to Drive or Reverse.
- ✔️ Poor Fuel Economy: Inefficient shifting leads to the engine working harder and consuming more fuel.
- ✔️ No Communication: A scan tool may be unable to communicate with the transmission module, indicating a complete failure.

Frequently Asked Questions
Do I need to have this TCM programmed by a dealer?
No. This Transmission Control Module comes pre-programmed to your vehicle’s VIN. It is ready for installation right out of the box, with no additional programming or dealer visits required.
Where is the TCM located on my 2007-2010 Saturn Vue?
On the 2007-2010 Saturn Vue, the TCM is typically found in the front left-hand (driver’s side) of the engine compartment. Always confirm the location on your specific vehicle before beginning the replacement.
Will this module fix a P0700 diagnostic trouble code?
A P0700 code is a general fault code indicating the TCM has detected a problem. While this module often resolves the root cause of a P0700, it’s essential to diagnose any other specific codes that are present. In many cases where the TCM itself is faulty, replacing it will clear the code.
Is this compatible with other GM vehicles?
Yes, the T42 TCM was used in a wide variety of GM vehicles from 2006-2014, including models like the Chevrolet Cobalt, HHR, Impala, GMC Sierra, and Buick LaCrosse. This part is programmed specifically for your vehicle to ensure proper function.
What happens if I continue driving with a bad TCM?
Continuing to drive with a faulty TCM can lead to more severe transmission damage. Erratic shifting and pressure control issues can cause excessive wear on clutches and other internal mechanical parts, potentially leading to a complete transmission failure that is much more expensive to repair.
