If the transmission in your 2006 Pontiac Pursuit is acting up—slamming into gear, refusing to shift, or putting your car into a frustrating ‘limp mode’—the cause is often not a costly mechanical failure, but a faulty Transmission Control Module (TCM). I’ve seen it countless times in my 20+ years as a technician: a vehicle owner is quoted thousands for a transmission rebuild when all they needed was this simple electronic component. This T42 TCM, part number 24240400, is the definitive, reliable solution to restore crisp, predictable shifting to your GM vehicle.
The real value here is our expert VIN programming service. Before this module ships, we flash it with your car’s specific Vehicle Identification Number and the latest GM software updates. This means it arrives at your door ready for a true plug-and-play installation, completely eliminating the need for an expensive trip to the dealership for programming. It’s a direct fix that saves you time, money, and diagnostic headaches.
Case Study: A Tricky Diagnosis
A customer brought in a 2007 Pontiac G6, a close cousin to the Pursuit, with a classic complaint: intermittent harsh 1-2 shifts and a check engine light with code P0700 (Transmission Control System Malfunction). Another shop had already replaced two shift solenoids with no improvement. After a quick data scan, I saw erratic command signals from the TCM. Instead of tearing into the transmission, we installed one of our VIN-programmed T42 modules. The total time was under 30 minutes. The car shifted perfectly on the test drive, the code was gone, and the customer avoided a $2,500+ bill for an unnecessary transmission teardown. This is why targeting the TCM first for electronic faults is so critical.
Is Your Pontiac Exhibiting These Telltale Signs?
A failing TCM can mimic serious internal transmission problems. Before you assume the worst, check if you’re experiencing any of these common symptoms, which often point directly to this module.
- âś” Harsh, erratic, or delayed gear shifts that make driving uncomfortable.
- âś” Vehicle is stuck in one gear (often 2nd or 3rd), a condition known as “limp mode.”
- âś” The Check Engine Light or Transmission Warning Light is illuminated on your dash.
- âś” Diagnostic Trouble Codes (DTCs) are present, such as P0700, P0750-P0758 (solenoid circuit faults), or U-codes indicating lost communication.
- âś” A noticeable drop in fuel economy as the transmission isn’t operating efficiently.
- âś” The transmission seems to slip out of gear or fails to engage properly from a stop.
A Straightforward Guide to Installation
Replacing the TCM on your Pontiac Pursuit is a job most DIYers can handle in their own driveway. For the 2006 Pursuit, you’ll find the module located on the driver’s side, attached to the strut tower. Follow these simple steps for a successful replacement.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts and to help reset the system.
- Locate the Old Module: Find the TCM on the LH strut tower. It’s a small metal box with electrical connectors.
- Disconnect and Remove: Carefully unplug the wiring harnesses. They have locking tabs that may need to be gently pried up. Then, unbolt the module from its mounting bracket.
- Install the New TCM: Bolt the new, pre-programmed module into place. Securely plug the wiring harnesses back in until they click, ensuring a solid connection.
- Reconnect and Verify: Reconnect the battery terminal. Start the vehicle and allow it to idle for a few minutes. Take it for a test drive to confirm that shifting has returned to normal. Use a scan tool to clear any stored fault codes if they persist.

Frequently Asked Questions
What does ‘VIN Programmed’ actually mean?
It means we load your car’s unique 17-digit Vehicle Identification Number (VIN) and the corresponding factory software onto the module before we ship it. This makes the TCM a direct plug-and-play part, recognized by your car’s other computers without needing a trip to the dealer for expensive programming.
Do I need any special tools for this installation?
No special tools are required. Basic hand tools, such as a socket set to remove the mounting bolts and possibly a small flathead screwdriver to help with the connector tabs, are all you should need for the job.
Will this fix a P0700 trouble code?
A P0700 code is a general code indicating a fault has been detected within the transmission control system. In many cases, a failing TCM is the root cause that triggers this code, along with more specific solenoid or communication codes. Replacing the TCM is a very common and effective fix for a P0700, provided the transmission’s mechanical parts and wiring are in good condition.
Is there a core charge for this part?
No, there is no core charge. You are not required to send your old, faulty module back to us, which saves you the hassle and cost of return shipping.
What if this doesn’t fix my problem?
Our module comes with a one-year warranty against defects. If the TCM is diagnosed as faulty, we will stand by our product. However, if your vehicle’s issues are caused by other problems (e.g., bad wiring, faulty solenoids, or mechanical failure), this part may not resolve them. We always recommend proper diagnosis before ordering.
