Restore Your Vehicle’s Shifting Performance
Are you experiencing erratic shifting, a check engine light, or the dreaded “limp mode” in your Pontiac Solstice, Saturn Sky, or Cadillac? A failing Transmission Control Module (TCM) is often the culprit behind these frustrating and potentially damaging issues. The TCM is the electronic brain of your automatic transmission, responsible for calculating shift points, controlling fluid pressure, and ensuring smooth, efficient operation. When it fails, it can leave you with an unreliable and unpleasant driving experience.
This replacement Transmission Control Module, part number 24235224, is the definitive solution to get your vehicle back on the road and performing as it should. We take the guesswork and high dealership costs out of the equation. Unlike a generic module from a parts store, this unit is meticulously programmed with the latest GM software updates specifically for your vehicle using the VIN you provide. This ensures perfect communication between the TCM, the engine, and other vehicle systems, restoring the original factory performance and reliability.
From the Diagnostic Bay
We had a 2008 Pontiac Solstice roll into the shop with a classic complaint: “It shifts hard sometimes, and other times it feels like it’s slipping.” The customer had already replaced the transmission fluid, but the problem persisted. A scan revealed a U0101 code – Lost Communication with TCM. After checking the wiring and connectors, we confirmed the internal electronics of the original TCM were failing intermittently. Instead of a costly trip to the dealer for a new module and programming, we installed one of our pre-programmed units. The customer provided their VIN, we received the ready-to-install module, and the swap took less than an hour. The Solstice was back to shifting smoothly, the check engine light was gone, and the customer saved hundreds of dollars and a lot of time.
Symptoms of a Failing Transmission Control Module
- ✔ Harsh, jerky, or delayed gear shifts.
- ✔ The transmission getting stuck in a single gear (limp mode).
- ✔ Check Engine Light illuminated with transmission-related fault codes (e.g., P0700, U0101).
- ✔ Inability to shift into or out of a specific gear.
- ✔ Poor fuel economy due to inefficient shifting.
- ✔ The vehicle may not start or shift out of Park.
- ✔ Inaccurate gear indicator on the instrument cluster.

Frequently Asked Questions
Do I need to program this module?
No. This is the primary benefit of our service. We program the module to the VIN you provide before shipping it. This makes it a plug-and-play installation, saving you a trip to the dealership and expensive programming fees.
What is a VIN and why do you need it?
The VIN, or Vehicle Identification Number, is a unique 17-digit code for your specific car. It contains information about the make, model, year, engine, and factory options. We use this to load the exact, correct software from GM onto your module, ensuring it works perfectly with your vehicle’s systems.
Where is the TCM located on my 2007 Solstice?
On the 2006-2010 Pontiac Solstice and Saturn Sky, the Transmission Control Module is typically located on the left-hand (driver’s side) front frame rail in the engine bay. Please consult a service manual for your specific vehicle for the exact location and removal procedure.
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 a faulty TCM can cause a P0700 code, it’s essential to have a full diagnostic scan to retrieve the more specific codes stored within the TCM itself. This part will resolve issues directly caused by a failing module.
What happens if I don’t provide my VIN?
Providing your VIN is mandatory for this part. We cannot ship the module without programming it, as an unprogrammed module will not function in your vehicle. Please enter your VIN in the notes section at checkout or reply to your order confirmation email with it to prevent delays.
