Is Your Vehicle Shifting Erratically or Stuck in Gear?
There’s nothing more frustrating than a transmission that doesn’t know what to do. Harsh shifts, delayed engagement, and a sudden check engine light can ruin your day and make you question your vehicle’s reliability. These are classic signs of a failing Transmission Control Module (TCM). Instead of facing a costly and time-consuming dealership visit, take control with our pre-programmed 24235732 GM T42 TCM. This is the direct, plug-and-play solution designed to restore the smooth, predictable performance you depend on, getting you back on the road with confidence.
Common Failure Symptoms & Your Direct Solution
A faulty TCM can manifest in numerous ways, often mimicking more severe mechanical failures. If you’re experiencing any of the following, this module is your definitive fix:
- Harsh or Erratic Shifting: Abrupt, jerky gear changes or a feeling of the transmission slipping between gears.
- Stuck in “Limp Mode”: The vehicle refuses to shift out of a single gear (often 2nd or 3rd) to prevent further damage.
- Warning Lights: A persistent Check Engine Light or specific Transmission Warning Light on your dash.
- Diagnostic Trouble Codes (DTCs): Common codes like P0700 (Transmission Control System Malfunction) or various solenoid-specific codes (e.g., P0750-P0758).
- No Shifting: Complete failure to upshift or downshift, leading to poor acceleration and terrible fuel economy.
This expertly prepared 24235732 GM T42 TCM directly addresses the electronic root cause of these issues, restoring communication and precise control over your vehicle’s automatic transmission.

Expert Insight: Why VIN Programming is Non-Negotiable
Many sellers offer “blank” or used modules, but on modern GM vehicles, that’s a recipe for failure. The TCM is the brain of your transmission, and it must be perfectly matched to your vehicle’s specific engine, tire size, and gear ratios. Our VIN-programming process doesn’t just make the part work—it loads the latest factory software updates from GM. This often corrects underlying drivability issues that may have existed from the factory, ensuring your transmission operates not just like new, but better than new.
Frequently Asked Questions
What does a Transmission Control Module (TCM) do?
The TCM is a computer that acts as the brain for your automatic transmission. It collects data from various sensors on the engine and vehicle, and uses that information to control exactly when and how the transmission shifts gears, engages the torque converter, and manages fluid pressure for optimal performance and fuel economy.
Is this module difficult to install?
For most DIYers with basic tools, the installation is very straightforward. The TCM is typically located in the engine bay and is accessible. The process usually involves disconnecting the battery, unplugging the electrical connectors, unbolting the old module, and installing the new one. Since our modules are pre-programmed, there are no complex computer steps required afterward.
Why is VIN programming so important?
VIN programming loads your vehicle’s exact specifications into the TCM. Without it, the module won’t know the correct shift points, gear ratios, or tire size, leading to poor performance, error codes, and potential damage to the transmission. Our pre-programming service makes this a true plug-and-play part.
Will this fix my P0700 trouble code?
The P0700 code is a general fault code indicating that the TCM has detected a problem and has requested the Check Engine Light to be turned on. While this module often resolves the root cause that triggers a P0700, it’s always wise to use a scanner to check for other, more specific codes (like solenoid or sensor codes) to confirm the TCM is the issue.
Do I need to return my old TCM?
No, there is no core charge for this part. You can keep your old module, which saves you the time, cost, and hassle of shipping a core back.
How do I know if this 24235732 GM T42 TCM is right for my vehicle?
The best way is to cross-reference the part number on your existing module with the list of compatible service numbers in our description. You can also use our vehicle fitment tool or contact our expert support team with your VIN, and we’ll be happy to confirm compatibility for you.
