End Your Transmission Troubles with a Plug-and-Play Solution

Are you experiencing frustrating and unpredictable transmission behavior in your Cadillac, Saturn, or Pontiac? Issues like harsh shifting, getting stuck in one gear, or a persistent Check Engine Light can turn a pleasant drive into a stressful ordeal. These are classic signs of a failing Transmission Control Module (TCM). This programmed 24239785 TCM is the definitive, hassle-free solution to restore your vehicle’s performance and your peace of mind.

Common Symptoms & Your Solution

A faulty TCM can manifest in numerous ways, often mimicking internal transmission failure and leading to incorrect diagnoses. If you’re noticing any of the following, this module is the component you need:

  • Erratic or harsh gear changes
  • Delayed engagement into Drive or Reverse
  • Vehicle stuck in “limp mode” (usually 2nd or 3rd gear)
  • Illuminated Check Engine Light with transmission-related Diagnostic Trouble Codes (DTCs), such as P0700, P0751, P0756, or U0101 (Loss of Communication)
  • Inaccurate or non-functional gear indicator on the dash

Instead of wrestling with a used module that requires expensive dealer programming or a generic part that doesn’t work, our service provides a direct, ready-to-install fix. We take your vehicle’s unique Vehicle Identification Number (VIN) and flash this module with the latest, most stable software updates directly from GM. This ensures perfect communication between the TCM, the engine, and other vehicle systems, just as the factory intended.

Expert Insight: The ‘Brain’ of Your Transmission

Think of the TCM as the dedicated computer for your automatic transmission. It constantly analyzes data from sensorsโ€”like vehicle speed, engine RPM, and throttle positionโ€”to make split-second decisions on when and how to shift gears. When it fails, the communication breaks down, and the transmission’s precise mechanical operations become chaotic. By installing a precisely programmed 24239785 TCM with updated software, you aren’t just replacing a part; you’re restoring the intelligent control system that is essential for your vehicle’s performance, efficiency, and longevity.

Frequently Asked Questions

Do I need to do any programming after I receive the part?

No. We program the module to the VIN you provide during checkout. It will arrive ready to be installed, making it a true plug-and-play solution. Please double-check your VIN for accuracy before submitting your order.

Where is this TCM located on my vehicle?

The location varies by model. On the Saturn SKY and Pontiac Solstice, it’s typically found on the left-hand front frame rail. On Cadillac models like the SRX, STS, and CTS, it can be located in the engine compartment or under the dash on the right-hand side. Always consult a service manual for your specific vehicle for the exact location.

Will this fix my specific transmission error codes?

This programmed 24239785 TCM is the direct solution for a wide range of transmission-related DTCs, especially those indicating solenoid circuit faults, communication errors, or internal controller failures. While it resolves the most common electronic issues, you should always ensure the transmission’s mechanical components and wiring harness are in good condition.

What information do you need from me?

After you complete your purchase, you must provide us with your 17-digit Vehicle Identification Number (VIN). We cannot ship your part until we receive the VIN, as the programming process is specific to your vehicle’s factory configuration.

Is a core charge required for this part?

No, there is no core charge for this specific part. You do not need to send your old, faulty module back to us.
