Restore Peak Performance to Your SAAB 9-7X
Is your 2006-2009 SAAB 9-7X suffering from erratic shifting, getting stuck in gear, or displaying a transmission warning light? These are classic symptoms of a failing Transmission Control Module (TCM). The TCM is the electronic brain of your automatic transmission, responsible for orchestrating smooth gear changes, managing torque converter lockup, and ensuring overall driveline efficiency. When it fails, it can lead to frustrating performance issues, poor fuel economy, and potentially costly damage to your transmission’s mechanical components.
This genuine GM T42 Transmission Control Module, service part number 24235754, is the definitive solution for restoring your vehicle’s factory performance. We take the guesswork and dealership hassle out of the equation by pre-programming the module to your vehicle’s specific Vehicle Identification Number (VIN). This ensures it arrives ready for a plug-and-play installation, loaded with the latest software updates from General Motors for optimal shift patterns and reliability.
From the Diagnostic Bay
We recently had a 2008 SAAB 9-7X come into the shop with a classic complaint: harsh 1-2 shifts and occasionally getting stuck in 3rd gear (limp mode). The customer had already spent a significant amount of money at another shop replacing shift solenoids, with no improvement. A quick scan showed a P0700 code (Transmission Control System Malfunction). Instead of throwing more parts at it, we inspected the TCM wiring and found no issues. The root cause was internal failure of the original module. After installing one of our VIN-programmed T42 modules, the vehicle shifted like it just rolled off the assembly line. The customer was thrilled to have their smooth-driving SUV back without an expensive trip to the dealer.
Common Symptoms of a Failing SAAB 9-7X Transmission Module
- ✔ Harsh, delayed, or erratic gear shifts that disrupt your driving experience.
- ✔ The vehicle enters “limp mode,” often getting stuck in a single gear (usually 2nd or 3rd) to protect the transmission.
- ✔ Check Engine Light or specific transmission warning lights are illuminated on your dashboard.
- ✔ Diagnostic Trouble Codes (DTCs) such as P0700, P0750, or other solenoid-related codes are stored in the system.
- ✔ Complete failure to upshift or downshift, leading to poor acceleration and high RPMs.
- ✔ A noticeable decrease in fuel efficiency as the transmission operates incorrectly.
- ✔ Intermittent electrical issues that seem to have no other cause.

Simple Installation Process
For the SAAB 9-7X, the TCM is conveniently located in the engine compartment on the left-hand (driver’s) side. The installation is straightforward for a DIY mechanic or any professional technician and typically takes less than 30 minutes.
- Safety First: Disconnect the negative terminal of your vehicle’s battery.
- Locate the Module: Find the TCM in the LH engine compartment.
- Disconnect and Remove: Carefully unplug the electrical connectors and unbolt the old module from its mounting bracket.
- Install the New Module: Bolt the new, pre-programmed module in place and securely reconnect the electrical harnesses.
- Final Steps: Reconnect the battery. While the module is plug-and-play, it’s always best practice to use a scan tool to clear any old fault codes from the vehicle’s memory.

Frequently Asked Questions
What does “VIN Programmed” mean for my SAAB?
VIN programming means we load the module with the specific software calibration file for your exact vehicle using your 17-digit VIN. This ensures the TCM works perfectly with your engine, axle ratio, and other systems, eliminating the need for a trip to the dealership for costly programming.
Will this fix a P0700 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 accompanying codes (like solenoid or sensor codes) that point to the specific issue. A faulty TCM is a very common cause for this code.
Are any special tools required for installation?
No special tools are required. Basic hand tools, such as a socket set to remove the mounting bolts, are all that’s needed. A code scanner is recommended to clear any stored DTCs after installation, but it is not required for the module to function.
Do I need to send my old TCM back?
No, there is no core charge for this part. You can keep, discard, or recycle your old module without any extra fees or hassle.
How can I be sure this fits my vehicle?
This module is a confirmed fit for all 2006, 2007, 2008, and 2009 SAAB 9-7X models. It is also compatible with a wide range of other GM vehicles. Providing your VIN at checkout guarantees we will program it correctly for your specific vehicle.
