Restore Peak Transmission Performance
Are you experiencing frustrating and unpredictable shifting in your vehicle? A faulty Transmission Control Module (TCM) is often the culprit behind issues like harsh gear changes, getting stuck in limp mode, or seeing that dreaded check engine light. This genuine GM T42 Transmission Control Module, service part number 24235732, is the definitive solution for a wide range of GM vehicles, including the 2007-2010 Saturn Vue. It arrives pre-programmed to your vehicle’s specific VIN, eliminating the need for expensive dealership visits and ensuring a seamless, plug-and-play installation.
From the Diagnostic Bay
We had a 2008 Chevy Silverado in the shop that was driving the owner crazy. It would shift hard from first to second gear when cold, and occasionally it would refuse to shift past third gear on the highway, triggering a transmission warning light. The owner had already replaced a shift solenoid with no luck. After hooking up our scan tool, we saw a generic P0700 code and some intermittent communication errors with the TCM. Instead of chasing electrical ghosts, we identified the internal T42 module as the weak link. We ordered a VIN-programmed unit, swapped it out in under 20 minutes (it was right next to the battery), cleared the codes, and the truck shifted like it just rolled off the factory floor. It’s a classic failure mode for these modules, and a pre-programmed replacement is the fastest, most reliable fix.
Is Your Vehicle Showing Signs of a Bad TCM?
A failing TCM doesn’t just affect comfort; it can impact your vehicle’s safety and fuel economy. If you’re noticing any of the following symptoms, it’s a strong indicator that your transmission control module needs attention.
- ✔️ Harsh, delayed, or erratic gear shifting.
- ✔️ The vehicle is stuck in a single gear (limp mode).
- ✔️ Check Engine Light or Transmission Warning Light is illuminated.
- ✔️ Diagnostic Trouble Codes (DTCs) such as P0700, P0750, or other solenoid-related codes are present.
- ✔️ Poor acceleration and decreased fuel efficiency.
- ✔️ Complete failure to shift gears or engage drive/reverse.

- Safety First: Always disconnect the negative battery terminal before starting any electrical work.
- Locate the Module: Identify the old TCM based on your vehicle’s layout.
- Disconnect and Remove: Carefully unplug the electrical connectors and unbolt the module from its mounting bracket.
- Install the New Module: Bolt the new, pre-programmed TCM into place and securely reconnect the wiring harnesses.
- Final Steps: Reconnect the battery. While the module is plug-and-play, it’s good practice to use a basic OBD2 scan tool to clear any stored diagnostic codes from the vehicle’s memory.

Frequently Asked Questions
What does a Transmission Control Module (TCM) do?
The TCM is the electronic brain of your automatic transmission. It receives data from various sensors on the engine and transmission to control shift points, line pressure, and torque converter clutch operation, ensuring smooth and efficient performance.
Do I need to have this module programmed by a dealer?
No. This module comes fully programmed to your vehicle’s unique VIN. This makes it a true plug-and-play solution, saving you the time, expense, and hassle of a trip to the dealership for programming.
Is this part difficult to install myself?
For most individuals with basic mechanical skills, the installation is straightforward. The TCM is typically located in an accessible part of the engine bay and can be swapped in under 30 minutes with common hand tools. Always disconnect the battery before you begin.
How can I be sure this part fits my exact vehicle?
This module fits a wide range of GM vehicles from 2006-2014. You can verify fitment by matching your original part number to the list of interchangeable numbers provided, or by using our website’s vehicle selection tool. Providing your VIN at checkout guarantees we program it correctly for your specific application.
What happens if I continue driving with a bad TCM?
Continuing to drive with a faulty TCM can lead to more severe transmission damage. Erratic shifting and incorrect line pressure can cause excessive wear on clutches and internal components, potentially leading to a complete transmission failure that is far more costly to repair.
