Get Your Tahoe Shifting Smoothly Again
Is your 2007-2009 Chevrolet Tahoe suffering from harsh shifts, getting stuck in gear, or throwing transmission codes? A failing Transmission Control Module (TCM) can turn your reliable family SUV into a source of constant frustration and worry. Restore confidence in your vehicle with our pre-programmed T42 TCM, the definitive, plug-and-play solution designed to get you back on the road quickly and safely, without an expensive trip to the dealership.
Common Symptoms & Your Solution
If you’re experiencing any of the following issues, a faulty TCM is the likely culprit. This module is the direct solution for:
- Abrupt, jerky, or delayed gear shifts
- The vehicle entering “limp mode,” often stuck in 2nd or 3rd gear
- An illuminated Check Engine Light or Transmission Warning Light
- Diagnostic Trouble Codes (DTCs) such as P0700, P0750, or other solenoid-related faults
- Failure to upshift or downshift properly, leading to poor acceleration and fuel economy
Installing our expertly programmed 2007-2009 Tahoe transmission control module resolves these issues by restoring precise communication between your engine and transmission, ensuring optimal performance and reliability.

Expert Insight: Why VIN Programming is Non-Negotiable
In modern vehicles like your Tahoe, the TCM isn’t just a simple controller; it’s a computer that uses vehicle-specific data—like tire size, axle ratio, and engine parameters—to make split-second shifting decisions. A generic, non-programmed module from a big-box store or salvage yard won’t have this critical information, leading to continued poor performance or even damage. Our VIN programming service ensures your new 2007-2009 Tahoe transmission control module has the exact software and calibrations from GM, making it a true, intelligent solution, not just a replacement part.
Frequently Asked Questions
What does “VIN Programmed” actually mean for me?
It means we handle all the complicated computer setup for you before we ship the part. You won’t need to pay a dealership or specialized shop hundreds of dollars for programming. This module is ready for installation right out of the box, saving you time, money, and hassle.
Is this part difficult to install myself?
For someone with basic mechanical skills, installation is straightforward. The TCM on a 2007-2009 Tahoe is typically located in the engine bay, next to the battery. The process involves disconnecting the battery, unplugging the electrical connectors, unbolting the old module, and installing the new one. It can often be completed in under 30 minutes.
Will this fix a P0700 trouble code?
A P0700 code is a general fault code indicating that the TCM has detected a problem. While this module often resolves the underlying issue causing the P0700, we always recommend a full diagnostic scan to check for any other specific codes (like solenoid or sensor faults) that may be present.
Do I need to send my old TCM back?
No, there is no core charge for this part. You can keep your old module, which simplifies the process and gets your vehicle repaired faster.
Is this the correct module for other GM vehicles?
Yes, this T42 TCM (service # 24252114) is compatible with a wide range of GM trucks, vans, and SUVs from 2006-2014. While this listing is optimized for the 2007-2009 Tahoe transmission control module, you can verify fitment for other models by checking the extensive compatibility list or contacting our support team.
