Restore Your Vehicle’s Drivability and Shift Quality
As a technician with over two decades of experience, I’ve seen countless drivers frustrated by transmission problems that seem to come out of nowhere. One day your 2005 Pontiac Pursuit is driving perfectly, and the next, it’s struggling to shift, lurching between gears, or throwing a check engine light that won’t go away. The culprit is often the Transmission Control Module (TCM)—the electronic brain responsible for every shift. When it fails, your driving experience suffers. This isn’t just an annoyance; it’s a reliability issue that can leave you stranded.
This replacement TCM is the definitive solution to get your vehicle back in top form. We take the guesswork and dealership hassle out of the equation. Before this part ever ships, we flash it with the latest official GM software, specifically matched to your vehicle using your VIN. This ensures that it communicates perfectly with your car’s powertrain, restoring the precise, smooth shifting you expect. This isn’t just a replacement part; it’s a direct-fit, plug-and-play fix for a complex problem.
Common Signs of a Failing TCM
- ✔ Erratic, harsh, or delayed shifting
- ✔ Vehicle gets stuck in one gear (limp mode)
- ✔ Check Engine Light is illuminated
- ✔ Loss of communication with the transmission module (DTC U0101)
- ✔ False transmission solenoid codes
- ✔ General transmission fault codes, such as P0700
A Technician’s Notebook
I recall a 2005 Cobalt—which shares its platform with the Pursuit—that came into my shop with a maddeningly intermittent no-shift condition. The owner had already spent money replacing shift solenoids, but the problem persisted, especially on hot days. After connecting my scan tool, I noticed the TCM would drop communication entirely after the engine bay warmed up. The internal circuits were failing under heat soak. We installed a VIN-programmed TCM just like this one, and the problem was solved for good. It’s a classic failure mode for these modules, and this part is the correct fix.
A Straightforward Guide to Installation
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- ✔ Locate the TCM: On your 2005 Pontiac Pursuit, the TCM is typically located behind the driver-side (LH) strut tower in the engine compartment.
- ✔ 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, pre-programmed TCM in place and tighten the bolts. Reconnect the electrical connectors, ensuring they click securely into place.
- ✔ Final Step: Reconnect the negative battery terminal. In most cases, the vehicle is ready to drive without any further procedures.

Frequently Asked Questions
Why do you need my VIN?
Your Vehicle Identification Number (VIN) is essential for us to load the exact, correct GM software for your car’s specific configuration. This ensures the TCM works perfectly with your engine and transmission, preventing compatibility issues.
Is this part truly plug-and-play?
Yes. Because we program the module to your VIN before shipping, it arrives ready to install. No additional programming or trips to the dealer are required. Just install it, reconnect your battery, and you’re ready to go.
Will this fix my check engine light?
If the check engine light and stored trouble codes (like P0700 or U0101) are caused by a failing TCM, this part is designed to resolve those issues. After installation, it’s a good practice to clear any old codes with a standard OBD-II scanner.
Is a core charge required?
No, there is no core charge for this part. You do not need to send your old, faulty module back to us.
How long does the programming process take?
Once you provide your VIN after purchase, we typically program and ship the module within one business day. Our goal is to get you the correct part as quickly as possible.
