Get Your Vehicle Shifting Smoothly Again
Is your Chevrolet, GMC, or other GM vehicle suffering from harsh shifting, getting stuck in gear, or displaying a persistent check engine light? A failing Transmission Control Module (TCM) can disrupt your vehicle’s performance and reliability, turning a dependable workhorse into a source of frustration. This professionally programmed T42 Transmission Control Module is the definitive solution to restore your transmission’s peak performance and get you back on the road with confidence.

If you’re experiencing any of the following issues, a faulty TCM is the likely culprit. This module is engineered to resolve these exact problems:
- Harsh, erratic, or delayed gear shifts
- Vehicle stuck in “limp mode” (often 2nd or 3rd gear)
- Illuminated Check Engine or Transmission warning lights
- Diagnostic Trouble Codes (DTCs) such as P0700, P0750, or other solenoid-related faults
- Failure to upshift or downshift properly
- Noticeable decrease in fuel efficiency
- Intermittent loss of communication with the transmission
By replacing your old unit with our Programmed 24239926 Transmission Control Module, you are installing a reliable, pre-configured component designed to function seamlessly with your vehicle’s specific systems from the moment it’s connected.

Expert Insight: The Critical Role of VIN Programming
In modern vehicles, the TCM isn’t just a simple controller; it’s a computer that communicates constantly with the Engine Control Module (ECM) and other vehicle systems. VIN programming ensures this communication is flawless. An unprogrammed module can lead to incorrect shift strategies, poor performance, and even new error codes. Our process loads your vehicle’s unique factory calibration file onto the module before it ships, ensuring it works perfectly as soon as you plug it in—just like the original part.
Frequently Asked Questions
What does “VIN Programmed” actually mean?
It means we load your vehicle’s unique Vehicle Identification Number (VIN) and the corresponding factory software onto the module before we ship it. This ensures it communicates perfectly with your vehicle’s engine and other systems, requiring no additional setup or expensive trips to a dealership.
Do I need special tools for installation?
No special tools are required. Installation typically involves basic hand tools to access the module, disconnect the battery, and swap the electrical connectors. After installation, using a standard OBD2 scan tool to clear any stored codes is recommended.
Will this fix a P0700 trouble code?
A P0700 code is a general fault code indicating the TCM has detected a problem. While this module often resolves the underlying issue causing the P0700, it’s essential to diagnose any other specific codes that are present (like for a particular solenoid) to confirm the TCM is the root cause.
Is there a core charge for my old part?
No, there is no core charge required for this part. You can keep or dispose of your old module without the hassle of sending it back.
How can I be sure the TCM is the problem?
Common symptoms like erratic shifting, being stuck in one gear (limp mode), and specific transmission-related diagnostic codes are strong indicators. If you’ve ruled out low fluid levels and mechanical issues, the TCM is the most likely culprit. This Programmed 24239926 Transmission Control Module is the most reliable fix for these electronic failures.
