Frequently Asked Questions
What does VIN programming mean for me?
VIN programming means we flash the module with your vehicle’s specific software from GM before we ship it. This makes the unit ready for immediate installation without any need for a scan tool or a visit to the dealer for additional programming, saving you time and money.
Is this part difficult to install?
No, this is a very DIY-friendly repair. The TCM is typically located in the engine compartment next to the battery. The process involves disconnecting the battery, unplugging the electrical connectors from the old module, swapping it with the new one, and reconnecting everything. Most customers complete the job in under 30 minutes.
Will this fix my specific trouble code (e.g., P0700)?
A P0700 code is a general transmission fault request from the TCM to the Engine Control Module (ECM) to turn on the check engine light. While this module often resolves the root cause of the P0700 and related solenoid codes, you should always diagnose the specific codes stored in the TCM. If those codes point to an internal module failure, this part is the correct solution.
Do I need to send my old part back?
No, there is no core charge for this part. You can keep your old module, eliminating the hassle and expense of return shipping.
Is this compatible with other GM trucks and SUVs?
Yes, the T42 TCM was used in a wide range of GM vehicles with 4-speed automatic transmissions like the 4L60E and 4L65E. While this listing is specific to the Tahoe, the module itself fits many models including the Silverado, Yukon, Sierra, and Express vans. Our VIN programming process ensures it works perfectly for your specific application.
