Get Your GM Vehicle Shifting Smoothly Again
Is your Chevrolet Express 3500 or other GM vehicle suffering from harsh shifting, getting stuck in gear, or throwing transmission codes? A faulty Transmission Control Module (TCM) is often the culprit, disrupting communication and causing performance issues that can sideline your vehicle. This T42 TCM, service number 24240449, is the definitive solution, arriving pre-programmed to your vehicle’s specific VIN for a true plug-and-play repair that gets you back on the road without a mandatory trip to the dealership.

Installing this pre-programmed 2006-2014 Express 3500 transmission control module is the most effective way to resolve these problems, restoring the precise, factory-intended operation of your automatic transmission.

Frequently Asked Questions
What does a Transmission Control Module do?
The TCM acts as the brain for your automatic transmission. It uses data from various sensors to control shift solenoids, manage fluid pressure, and determine the optimal gear for performance and fuel efficiency. When it fails, the transmission can’t operate correctly.
Is this TCM difficult to install?
Installation is generally straightforward for someone with basic mechanical skills. The module is typically located in the engine bay and can be replaced in under 30 minutes. The key benefit of our module is that no post-installation programming is required, making the job much simpler.
Will this module 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 root cause that triggers a P0700, it’s essential to diagnose any other specific codes that appear alongside it. In many cases, a faulty TCM is the primary issue.
Do I need to program this module?
No. This is the biggest advantage of our product. We pre-program the module to your vehicle’s VIN number before it ships. It arrives ready for plug-and-play installation, saving you the time, cost, and hassle of a dealership visit.
What happens if I install the wrong TCM?
Installing a non-programmed or incorrect module can lead to serious issues, including no-start conditions, incorrect shifting, damage to the transmission, or persistent error codes. Our VIN programming service ensures you receive the correct, compatible part for your vehicle.
Is a core charge required for this 2006-2014 Express 3500 transmission control module?
