Restore Peak Performance to Your Pontiac Pursuit’s Transmission
Is your 2006 Pontiac Pursuit suffering from harsh shifting, delayed gear engagement, or getting stuck in limp mode? These are classic signs of a failing Transmission Control Module (TCM). The TCM is the electronic brain of your automatic transmission, responsible for orchestrating every gear change, managing torque converter lockup, and monitoring system health. When it fails, it can lead to a frustrating and potentially unsafe driving experience. This VIN-programmed GM T42 TCM, compatible with service number YNXS, is the definitive solution to restore the smooth, reliable performance your vehicle had when it left the factory.
From the Diagnostic Bay
We once had a 2008 Chevy Impala come in with what the owner was convinced was a completely shot transmission. It was banging into gear and the check engine light was on with a P0700 code. Another shop had quoted him thousands for a full transmission rebuild. After a quick scan, we saw several solenoid circuit codes pointing to an electrical fault. Instead of tearing down the transmission, we inspected the TCM and its wiring. The module itself had failed internally. We installed one of our VIN-programmed T42 TCMs, cleared the codes, and the car drove perfectly. The customer saved a fortune and drove away with a simple, effective fix. It’s a powerful reminder to always diagnose the electronics before condemning the hard parts.
Diagnosing Your 2006 Pursuit Transmission Module Failure
A faulty TCM can manifest in various ways, often mimicking the symptoms of major mechanical transmission failure. Before assuming the worst, it’s crucial to understand the signs that point directly to the module. If your vehicle is experiencing a combination of the issues below, there is a high probability that your 2006 Pursuit Transmission Module is the culprit. This module is a direct-fit replacement, pre-programmed to your vehicle’s specific VIN to ensure seamless communication with the Powertrain Control Module (PCM) and other vehicle systems.
Key Signs of a Failing T42 TCM
- ✔ Erratic Shifting: Your transmission may shift harshly, slam into gear, or shift at incorrect times, causing jerky acceleration or deceleration.
- ✔ Warning Lights: The Check Engine Light or a dedicated transmission warning light will often illuminate on your dashboard. Common Diagnostic Trouble Codes (DTCs) include P0700, P0750, and other solenoid-specific codes.
- ✔ Limp Mode Activation: The vehicle may enter a fail-safe or “limp” mode, where it gets stuck in a single gear (usually 2nd or 3rd) to prevent further damage.
- ✔ Delayed Engagement: You might notice a significant delay when shifting from Park into Drive or Reverse.
- ✔ Poor Fuel Economy: Inefficient shifting and improper torque converter lockup caused by a bad TCM can lead to a noticeable drop in gas mileage.
- ✔ No Communication: In severe cases, a scan tool may be unable to communicate with the TCM, indicating a complete module failure.

This part is a direct replacement for a wide range of GM vehicles and interchanges with numerous part numbers, including 24252114, 24234503, 24230461, 24242391, and YNXS. Installation is simple for a DIY mechanic or professional technician, typically located in the engine bay on the LH strut tower for the Pontiac Pursuit. Always remember to disconnect the battery before starting the replacement to allow the vehicle’s systems to reset.
Will this TCM fit my vehicle if it’s not a 2006 Pontiac Pursuit?
Yes, this T42 TCM is compatible with a wide range of 2006-2014 General Motors vehicles equipped with 4-speed automatic transmissions like the 4L60E and 4L65E. Please review the detailed fitment list on this page or contact us with your VIN to confirm compatibility.
What is VIN programming and why is it necessary?
VIN programming loads your vehicle’s specific software and calibration files onto the module. This ensures the TCM communicates correctly with your engine controller and other systems, controlling shift points, line pressure, and other critical functions precisely for your exact vehicle configuration. Without it, the module will not work.
Do I need any special tools for installation?
Basic hand tools like a socket set are typically all that’s required for the physical installation. After installation, it is recommended to use a standard OBD2 scan tool to clear any stored diagnostic trouble codes from the vehicle’s memory.
Is there a core charge for this part?
No, we do not require a core charge. You can keep your old part, which saves you the time, money, and hassle of shipping it back.
What happens if I install it and still have problems?
Our modules are rigorously tested and come with a one-year warranty. If you continue to experience issues, it may indicate another underlying problem with the transmission wiring, solenoids, or mechanical components. Our expert support team is available to help you troubleshoot further.
