Restore Peak Performance to Your SAAB 9-7X
Is your 2006-2009 SAAB 9-7X experiencing frustrating transmission issues like harsh shifting, delayed gear engagement, or getting stuck in limp mode? 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 shift with precision. When it fails, drivability suffers, and warning lights appear. This replacement T42 TCM, service number 24239224, is the definitive solution to restore your vehicle’s smooth and reliable operation.
This module is not just a replacement part; it’s a complete, ready-to-install solution. We pre-program each unit to your vehicle’s specific Vehicle Identification Number (VIN) before shipping. This critical step ensures seamless communication between the TCM and your vehicle’s other systems, eliminating the need for an expensive trip to the dealership for programming. Simply install the module, and you’re ready to get back on the road with confidence.
From the Diagnostic Bay
We recently had a 2008 SAAB 9-7X come into the shop with the check engine light on and the transmission stuck in 3rd gear. The owner was worried about a costly transmission rebuild. A quick scan showed a P0700 code (Transmission Control System Malfunction) and several solenoid circuit codes. Instead of shotgunning parts, we identified the root cause: an internally shorted TCM. We installed one of our VIN-programmed T42 modules. After a 25-minute installation and clearing the codes, the vehicle was shifting perfectly. The customer saved thousands compared to a transmission replacement and avoided dealership programming fees.
Diagnosing a Faulty SAAB 9-7X Transmission Module
A failing TCM can manifest in various ways, often mimicking mechanical transmission failure. Before condemning your transmission, check for these common electronic symptoms. A faulty SAAB 9-7X Transmission Module can disrupt communication, leading to poor performance and potential damage if not addressed. Recognizing these signs early can save you from more extensive repairs.
Common Symptoms of a Failing T42 TCM
- ✔ Harsh, erratic, or delayed gear shifts that disrupt smooth driving.
- ✔ Vehicle enters ‘limp mode,’ often getting stuck in a single gear (like 2nd or 3rd) to protect the transmission.
- ✔ Check Engine Light or Transmission Warning Light is illuminated on the dashboard.
- ✔ Diagnostic Trouble Codes (DTCs) are stored, such as P0700, P0750, or other solenoid-related faults.
- ✔ Complete loss of upshifting or downshifting capabilities.
- ✔ A noticeable decrease in fuel economy due to inefficient gear management.
- ✔ The transmission may seem to slip between gears or fail to engage properly from a stop.

Frequently Asked Questions
Does this module require programming at the dealership?
No, it does not. We pre-program this SAAB 9-7X Transmission Module to your vehicle’s VIN before it ships. This makes it a true plug-and-play part, saving you time and the high cost of dealership programming.
What is a TCM and what does it do?
The Transmission Control Module (TCM) is a computer that controls your automatic transmission. It reads data from various sensors in the engine and transmission to determine the optimal time to shift gears, control torque converter lockup, and manage fluid pressure for smooth and efficient operation.
Where is the TCM located on my SAAB 9-7X?
On the 2006-2009 SAAB 9-7X, the transmission control module is typically found in the engine compartment on the left-hand (driver’s) side. Always confirm the location before beginning installation.
Will this part fix my P0700 trouble code?
A P0700 code is a general fault code indicating the TCM has detected a problem. While a failing TCM is a very common cause, this code can also be triggered by other issues. However, if you are experiencing shifting problems along with this code, replacing the TCM is the most likely solution.
Is there a core charge for this part?
No, there is no core charge. You are not required to send your old, faulty module back to us, which simplifies the repair process for you.
