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 check engine light? These are classic signs of a failing Transmission Control Module (TCM). The TCM is the electronic brain of your automatic transmission, responsible for orchestrating every gear change, managing torque converter lockup, and ensuring smooth, efficient operation. When it fails, it can leave your vehicle feeling unreliable and unsafe. This OEM-quality T42 TCM, part number 24234503, is the definitive solution to restore your vehicle’s drivability and peace of mind.
From the Diagnostic Bay
We recently had a 2008 Saab 9-7X come into the shop with a persistent P0700 code and harsh 1-2 shifts. The owner had already spent a significant amount of money replacing shift solenoids based on a generic diagnosis, but the problem remained. After a quick scan and data stream analysis, we identified communication dropouts from the original TCM. Instead of another costly and ineffective component replacement, we installed one of our VIN-programmed T42 modules. The installation took less than 30 minutes. After clearing the codes, the Saab shifted perfectly on the test drive. The owner was thrilled to have his vehicle back in proper working order without the guesswork and wasted expense of chasing the wrong parts.
Diagnosing a Faulty Saab 9-7X Transmission Module
A failing TCM can manifest in various ways, often mimicking mechanical transmission problems. Before condemning your transmission, it’s crucial to consider the module. This component is the central command for your 4L60E, 4L65E, or 4L70E transmission. Our replacement module is engineered to resolve these issues permanently.
Common Symptoms of TCM Failure
- ✔ Harsh, erratic, or delayed gear shifts that disrupt your driving experience.
- ✔ Vehicle entering “limp mode,” often stuck in 2nd or 3rd gear, with limited power.
- ✔ Illumination of the Check Engine Light or Transmission Warning Light on your dashboard.
- ✔ Specific Diagnostic Trouble Codes (DTCs) such as P0700, P0750 series (solenoid faults), or communication errors.
- ✔ Failure to upshift or downshift correctly, leading to poor acceleration and fuel economy.
- ✔ Intermittent electrical problems that seem to have no other cause.
- ✔ In severe cases, a complete loss of transmission function.

Frequently Asked Questions
Is any additional programming required after installation?
No. This module arrives fully programmed to your vehicle’s specific VIN. It is a plug-and-play solution that does not require any further action from a dealership or mechanic. Just install it, clear any old codes, and drive.
Where is the TCM located on my 2007 Saab 9-7X?
On the 2006-2009 Saab 9-7X, the Transmission Control Module is located in the engine bay, typically on the left-hand (driver’s side) in the engine compartment.
Will this fix a P0700 transmission fault 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 always best to scan for more specific codes (like P0751, P0756, etc.) to confirm the diagnosis. In many cases where the TCM is faulty, replacing it will clear the P0700 and related codes.
What is the difference between a T42 and other TCMs?
The T42 is the specific hardware platform used by GM for the transmission control module in a wide range of vehicles from this era, including your Saab 9-7X. It is designed to control 4-speed automatic transmissions like the 4L60E series. Our module is the correct T42 platform for your vehicle.
Is there a core charge for this part?
No, we do not require a core charge. You can keep your old module, which saves you the time, cost, and hassle of shipping it back.
