Restore Smooth Shifting to Your 2006 Pontiac Pursuit
If you’re dealing with the frustration of a transmission that slams into gear, refuses to shift, or has left you stuck in limp mode, you’re not alone. These are classic signs of a failing Transmission Control Module (TCM). As the electronic brain of your automatic transmission, a faulty TCM can make your 2006 Pontiac Pursuit feel unpredictable and unsafe. This replacement T42 TCM, part number YNXS, is the definitive solution. It arrives expertly programmed to your vehicle’s specific VIN, eliminating the need for expensive dealership visits and ensuring a seamless, plug-and-play installation.
Case Study: A Tricky Diagnosis
I recently had a 2006 Pontiac G6 in the bay—a sister car to the Pursuit—with a persistent check engine light and what the owner described as ‘violent’ shifting. The scanner showed codes for a couple of shift solenoids (P0753, P0758). The owner had already replaced the solenoids, but the problem remained. This is a scenario I’ve seen hundreds of times. The issue wasn’t the solenoids themselves, but the TCM’s internal driver circuits failing to properly command them. After installing one of our VIN-programmed T42 modules, all the codes cleared and the car shifted like it just rolled off the factory line. It saved the customer from a costly and unnecessary transmission teardown.
Is Your Pontiac Exhibiting These Transmission Woes?
- ✔ Harsh, erratic, or delayed gear shifts that make driving uncomfortable.
- ✔ The vehicle is stuck in a single gear (limp mode), often 2nd or 3rd.
- ✔ Check Engine Light or Transmission Warning Light is illuminated on your dash.
- ✔ Diagnostic Trouble Codes (DTCs) are present, such as the general P0700 or specific solenoid codes (e.g., P0750-P0774).
- ✔ The transmission fails to upshift or downshift correctly, leading to poor acceleration.
- ✔ A noticeable drop in fuel economy due to inefficient gear management.
- ✔ Intermittent loss of communication with the TCM, causing unpredictable behavior.

This isn’t just a replacement part; it’s a comprehensive repair solution. The most significant benefit is our pre-programming service. We flash the module with the latest GM software calibrated specifically to your car’s VIN. This means the module is ready to install right out of the box, restoring communication between your engine and transmission for optimal performance. Built to meet or exceed original equipment specifications, this module ensures long-term reliability for your vehicle’s powertrain.
A Straightforward Guide to Installation
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before beginning work.
- ✔ Locate the Module: On the 2006 Pontiac Pursuit, the TCM is typically found on the driver’s side, mounted to the strut tower in the engine bay.
- ✔ Disconnect and Remove: Carefully unplug the electrical connectors from the old module. Then, unbolt the module from its mounting bracket.
- ✔ Install the New Module: Mount the new TCM onto the bracket and securely plug in the electrical connectors. You should hear a click as they lock into place.
- ✔ Final Steps: Reconnect the negative battery terminal. While the battery disconnect often clears codes, it’s best practice to use a standard OBD2 scan tool to verify no codes are present. Start the vehicle and take it for a test drive to confirm smooth shifting.

Frequently Asked Questions About This TCM
Frequently Asked Questions
What does ‘VIN Programmed’ actually mean?
It means we load the module with the specific software calibration for your car using your 17-digit Vehicle Identification Number (VIN). This ensures it works perfectly with your engine, transmission, and other systems right out of the box, with no extra programming needed.
Will this module fix a P0700 trouble code?
A P0700 code is a general fault code indicating the TCM has detected a problem. Often, the TCM itself is the source of the fault. Replacing a failing TCM will typically resolve the P0700 code and any related specific codes (like for solenoids or sensors).
Is this a difficult part for a DIY mechanic to install?
For most of the listed vehicles, including the Pontiac Pursuit, this is a very straightforward job. The module is usually easy to access in the engine bay and requires only basic hand tools. The entire process often takes less than 30 minutes.
Do I need to return my old TCM (core charge)?
No, there is no core charge for this part. You can keep your old module, which saves you the time and hassle of shipping it back.
