Frequently Asked Questions
Do I need to program this module?
No. The main benefit of this part is that we program it to your vehicle’s VIN before shipping. It arrives ready for a plug-and-play installation, with no extra programming or dealership visits required.
Will this part fit other GM vehicles?
Yes, this T42 TCM is compatible with a wide range of 2006-2014 GM vehicles, including the Chevrolet Tahoe, GMC Sierra, Cadillac DTS, and more. Please verify your specific model and year in the compatibility list to ensure a perfect fit.
Is this module difficult to install?
For the SAAB 9-7X, the TCM is located in the left-hand side of the engine compartment, making it relatively accessible. Most experienced DIY mechanics can complete the installation in under 30 minutes with basic hand tools. We always recommend disconnecting the battery before starting the repair.
Will this fix my P0700 check engine light code?
A P0700 code is a general transmission fault request from the TCM to the Engine Control Module. While this programmed SAAB 9-7X transmission control module is the direct solution for the internal failure causing the code, you should always use a scan tool to check for other specific transmission codes (e.g., P0751, P0756) to confirm the diagnosis.
What happens if I don’t replace a failing TCM?
Continuing to drive with a faulty TCM can lead to more severe transmission damage. Erratic shifting can cause excessive wear on clutches and internal components, potentially leading to a complete transmission failure that is far more costly to repair.
Is a core charge required?
No, we do not require a core charge for this part. You can keep your old module without the hassle of returning it.
