Experiencing Erratic Shifting or a Stuck Check Engine Light?
There’s nothing more frustrating than when your vehicle’s transmission stops behaving predictably. The hesitation, harsh shifts, or sudden lurch into ‘limp mode’ can ruin your driving experience and leave you questioning your car’s reliability. If your Pontiac Solstice, Saturn Sky, or Cadillac is suffering from these issues, the problem often points directly to a failing Transmission Control Module (TCM). This isn’t just a component; it’s the brain of your automatic transmission, and when it falters, the entire system suffers. We provide the definitive, hassle-free solution to get you back on the road with confidence.
Common Symptoms & Your Solution
A faulty TCM can manifest in several ways, often triggering diagnostic trouble codes (DTCs) and noticeable performance problems. If you’re experiencing any of the following, this module is the solution you need:
- Harsh or delayed gear engagement
- Slipping between gears or failure to shift
- Vehicle stuck in one gear (Limp Mode)
- Check Engine Light illuminated with codes like P0700, P0751, P0756, U0100, or U0101
- No communication with the transmission module via a scan tool
This programmed 24239785 TCM is the direct answer to these problems. We take all the guesswork and expensive dealer visits out of the equation by pre-programming the unit specifically for your vehicle using the VIN you provide. It arrives ready for a straightforward installation, restoring the precise, smooth shifting your car was designed to deliver.

An Expert’s Note: We once had a customer with a beautiful Pontiac Solstice GXP. He was chasing a persistent shifting issue for months, replacing sensors and solenoids with no luck. The dealer quoted him an astronomical price for a new TCM plus programming. He was about to give up on the car he loved. We sent him our programmed 24239785 TCM, he installed it in his garage in under an hour, and his problem was completely solved. It’s a reminder that often, the most complex-seeming transmission issues come down to having a properly functioning and correctly programmed control unit. Don’t chase symptoms; fix the source.
Frequently Asked Questions
How do I provide my VIN number?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). You can typically add it as a note during checkout or reply to your order confirmation email. We cannot ship the part until we receive your VIN, as the programming is specific to your car.
Is this a difficult part to install?
On models like the Solstice and Sky, the TCM is located on the LH front frame rail, making it relatively accessible. For other models, it may be in the engine compartment or under the dash. Installation is generally straightforward for a competent DIY mechanic or any professional technician. The key benefit is that no special programming tools are needed after installation.
Will this part fix my specific transmission problem?
This programmed 24239785 TCM is the correct solution for failures of the electronic module itself. While it resolves the most common transmission control issues, it’s essential to ensure your vehicle’s problem is not mechanical (e.g., a bad clutch pack or faulty internal wiring). If you have communication codes or symptoms listed above, the TCM is the most likely culprit.
What does ‘Plug and Play’ really mean?
It means the module arrives ready to be installed without requiring a trip to the dealer for expensive software flashing. Once installed, your vehicle will recognize and communicate with the new TCM. In some cases, a simple ‘relearn’ procedure may be needed, which can often be done without special tools.
Do you need my old part back?
This listing does not require a core return. You can keep or dispose of your old, faulty module, saving you the time and expense of return shipping.
