If you’re dealing with erratic shifting, a check engine light, or your 2006-2009 SAAB 9-7X is stuck in limp mode, a failing Transmission Control Module (TCM) is the likely culprit. As the brain of your automatic transmission, the TCM is responsible for every gear change. When it fails, drivability suffers. This is a direct-fit, OEM-quality T42 TCM, service part number 24235732, designed to restore the precise, smooth performance your vehicle had when it left the factory.
The biggest challenge with replacing a TCM has always been the expensive and time-consuming trip to the dealership for programming. We eliminate that step entirely. By providing your vehicle’s VIN at checkout, we program the module with the latest GM software specific to your SAAB 9-7X. This means it arrives at your door ready for a true plug-and-play installation, getting you back on the road faster and saving you hundreds of dollars in dealer fees.
From the Diagnostic Bay
I recently had a 2008 SAAB 9-7X in the shop that was giving the owner fits. The symptoms were all over the place—one day it would shift hard from 1st to 2nd, the next it would refuse to shift past 3rd gear, and it was throwing a generic P0700 transmission fault code. The owner had already replaced a shift solenoid with no luck. After testing the circuits, we confirmed the issue was internal to the TCM. Instead of a costly dealer replacement, we ordered a VIN-programmed unit. The installation took less than 20 minutes, and after clearing the codes, the SAAB drove perfectly. It’s a classic case where the right part, pre-programmed, saves hours of diagnostics and hundreds in labor.
Is Your SAAB 9-7X Exhibiting These Transmission Faults?
A faulty TCM can manifest in several ways. If you’re noticing any of the following, it’s time to consider a replacement 2006-2009 SAAB 9-7X TCM.
- ✔ Harsh, jerky, or delayed gear shifts.
- ✔ Vehicle is stuck in a single gear (limp mode), often 2nd or 3rd.
- ✔ The check engine light or transmission warning light is illuminated.
- ✔ Diagnostic Trouble Codes (DTCs) are present, such as P0700, P0750, P0753, or other solenoid-related faults.
- ✔ Inconsistent or no communication with the TCM via a scan tool.

A Straightforward Guide to Installation
You don’t need to be a professional mechanic to install this module. The process is simple and can be completed in your own driveway with basic hand tools.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate the Module: On the SAAB 9-7X, the TCM is typically found in the engine compartment on the left-hand (driver’s) side.
- Disconnect and Remove: Carefully unplug the electrical connectors from the old TCM. Then, unbolt the module from its mounting bracket.
- Install the New Module: Bolt the new, pre-programmed TCM into place and securely reconnect the electrical connectors.
- Final Steps: Reconnect the battery terminal. While the module is plug-and-play, it’s best practice to use a basic OBD2 scanner to clear any stored fault codes from the vehicle’s memory.
