Is Your SAAB 9-7X Shifting Erratically?
If you’re experiencing harsh shifts, delayed gear engagement, or your SAAB 9-7X 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 coordinating shift points, managing torque converter lockup, and ensuring smooth, efficient operation. When it fails, it can cause a cascade of problems that affect both drivability and safety.
This genuine GM T42 Transmission Control Module, service part number 24235340, is the definitive solution for your 2006-2009 SAAB 9-7X. We take the guesswork and high dealership costs out of the equation by pre-programming the module to your vehicle’s specific VIN. This ensures 100% plug-and-play functionality right out of the box, restoring your transmission’s performance to factory specifications.
From the Diagnostic Bay
We had a customer with a 2008 GMC Envoy (which shares the same platform as the 9-7X) who was chasing a persistent P0752 shift solenoid code. He had already spent hundreds replacing the A/B solenoids inside the transmission pan, but the harsh 1-2 shift and check engine light kept returning. After a quick scan, we saw erratic data from the TCM. The internal drivers that command the solenoids had failed. We installed a VIN-programmed T42 module, cleared the codes, and the truck was shifting perfectly in under an hour. He could have saved a lot of time and money by diagnosing the TCM first.
Common Symptoms of a Failing SAAB 9-7X TCM
- ✔ Unpredictable or harsh gear shifts.
- ✔ The vehicle gets stuck in a single gear (limp mode).
- ✔ Check Engine Light or Transmission Warning Light is illuminated.
- ✔ Diagnostic Trouble Codes (DTCs) such as P0700, P0750, or other solenoid-related faults are present.
- ✔ Delayed engagement when shifting from Park to Drive or Reverse.
- ✔ Poor fuel economy and potential for transmission overheating.
- ✔ Complete loss of communication with the module, leading to a no-start or no-shift condition.
