End Your Transmission Frustrations for Good
Are you battling erratic shifting, a transmission stuck in one gear, or a persistent check engine light on your Cadillac, Saturn, or Pontiac? These frustrating and often worrying symptoms point directly to a failing Transmission Control Module (TCM). Driving with a faulty TCM is not only annoying but can also lead to further transmission damage and unsafe driving conditions. It’s time to stop worrying about costly dealership diagnostics and complex repairs. This is the definitive, straightforward solution to restore your vehicle’s performance and your peace of mind.

If your vehicle is experiencing any of the issues below, a failing TCM is the most likely culprit. This pre-programmed module is engineered to be the direct solution for these exact problems:
- Harsh or delayed gear engagement
- Slipping between gears or getting stuck in ‘limp mode’
- Inaccurate or erratic speedometer readings
- Check Engine Light with transmission-related fault codes (e.g., P0700, P0751, P0756, U0101)
- Complete loss of communication with the transmission module
Our Programmed 24235224 TCM arrives ready for installation, taking the guesswork and high cost out of the equation. We handle the complex part—the programming—so you can get your vehicle back to perfect working order quickly and easily.

Expert Insight: The Critical Role of VIN Programming
As a technician with over two decades of experience, I’ve seen countless drivers attempt to save a few dollars by installing a used, non-programmed TCM. The result is almost always the same: the vehicle won’t start, the transmission won’t shift correctly, or new, more confusing error codes appear. Your vehicle’s computers are a network; the TCM must have the correct ‘digital handshake’—the VIN-specific software—to communicate with the Engine Control Module (ECM) and other systems. By providing a Programmed 24235224 TCM, we eliminate this critical failure point, giving you a part that works exactly as the factory intended, the first time.
Frequently Asked Questions
How do I provide my VIN for programming?
After you complete your purchase, simply send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot ship your part until we receive this information, as the programming is essential for the module to function in your vehicle.
Is this part truly ‘plug and play’?
Yes, in the sense that it does not require a trip to the dealership for expensive programming. It is pre-flashed to work with your vehicle’s specific configuration. After installation, some vehicles may require a simple ‘relearn’ procedure, which can often be done without special tools, to synchronize the new module with the transmission’s solenoids.
Which part number will I receive?
You will receive a fully compatible TCM that directly replaces part numbers 24235224, 24239785, and YLMU. We ensure the part you get is the correct, updated hardware for your application, programmed and ready to install.
How can I be sure my TCM is the problem?
While a professional diagnosis is always recommended, the symptoms listed above—such as harsh shifting, communication codes like U0101, and being stuck in gear—are classic indicators of a failed TCM. This module is the most common point of failure for these specific issues.
What if I install the wrong or a non-programmed module?
Installing a module that isn’t programmed to your VIN will result in a no-start condition, incorrect shifting, or persistent error codes. The anti-theft system may also be triggered. Our pre-programming service prevents all of these issues.
