Restore Smooth, Reliable Shifting to Your 2005 Pontiac Pursuit
If you’re dealing with the frustration of harsh shifts, delayed gear engagement, or a transmission that seems to have a mind of its own, you’re not alone. These are classic signs of a failing Transmission Control Module (TCM). As a technician with over two decades of experience, I’ve seen how a faulty TCM can sideline a perfectly good vehicle. This isn’t just an annoyance; it’s a critical component failure that can affect your car’s performance and safety. That’s why we offer this direct-fit, pre-programmed 2005 Pontiac Pursuit TCM as a reliable and straightforward solution.
Forget the expensive trip to the dealership and the hassle of scheduling a programming appointment. We handle the critical software flashing for you. Simply provide your vehicle’s VIN at checkout, and our experts will load the latest, most stable GM software updates specific to your car. This ensures optimal performance, corrects known factory bugs, and makes the installation process as simple as swapping the part. You receive a module that is truly ready to install right out of the box.
From the Diagnostic Bay: The Case of the Hesitant Cobalt
A customer brought in a 2005 Cobalt—which shares its platform and TCM with the Pursuit—complaining of intermittent, bone-jarring shifts from 1st to 2nd gear, but only when the engine was warm. No check engine light was on, making it a tricky diagnosis. After ruling out fluid issues and solenoids, we monitored the TCM data stream. We noticed the command signals were lagging right before the harsh shift occurred. The original TCM was failing internally under heat. We replaced it with one of our pre-programmed modules. The customer was back on the road in under an hour, without the typical dealership wait for programming. The problem was solved, and the car shifted better than it had in years, thanks to the updated GM software.
Is Your Transmission Showing These Symptoms?
A failing TCM can manifest in several ways. If you’re experiencing any of the following, it’s a strong indicator that your module may need replacement. Look out for:
- ✔ Unpredictable or harsh shifting between gears.
- ✔ The transmission getting stuck in one gear (limp mode).
- ✔ Delayed engagement when shifting from Park to Drive or Reverse.
- ✔ A lit Check Engine Light or Transmission Warning Light.
- ✔ Diagnostic Trouble Codes (DTCs) such as P0700, U0101 (Lost Communication with TCM), or solenoid-specific codes like P0751, P0756, or P0761.
- ✔ Poor fuel economy due to inefficient shifting.
A Straightforward Guide to Installation
Installing your new 2005 Pontiac Pursuit TCM is a manageable job for a DIY enthusiast. The module is located behind the driver’s side (LH) strut tower in the engine bay. Always consult a service manual for your specific vehicle, but here is a general guide to get you started.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate the TCM: On your Pursuit, open the hood and find the TCM mounted behind the driver’s side strut tower. You may need to move other components for clear access.
- Disconnect Connectors: Carefully unplug the electrical wiring harnesses connected to the old TCM. These connectors have locking tabs that need to be released before pulling.
- Remove the Old Module: Unbolt the old TCM from its mounting bracket. Keep the hardware, as you’ll need it to install the new part.
- Install the New Module: Mount your new, pre-programmed TCM onto the bracket and secure it with the original hardware.
- Reconnect Everything: Firmly plug the wiring harnesses into the new module until they click into place. Reconnect the negative battery terminal.
- Final Steps: Start the vehicle and allow it to idle for a few minutes. Take it for a test drive to confirm that the shifting issues have been resolved. The vehicle will perform a ‘relearn’ process as you drive.

Frequently Asked Questions
Why do you need my VIN?
Your VIN (Vehicle Identification Number) is essential for us to program the TCM with the exact software calibration GM released for your specific vehicle. This ensures perfect compatibility with your engine, transmission, and other options, guaranteeing proper function and smooth shifting.
Is this a plug-and-play part?
Yes! Because we program the module to your VIN before shipping, it arrives ready to be installed. No additional programming or trips to the dealer are required. Just install the module, and you’re ready to go.
Will this fix a ‘No Communication with TCM’ code (U0101)?
In many cases, yes. The U0101 code often indicates a complete internal failure of the TCM. While you should always check the wiring and connectors first, a faulty TCM is the most common cause. This replacement module is designed to resolve that communication link.
What if my original part number is not 24223112?
Please check the list of compatible part numbers in our description (e.g., 24226863, 24239427, etc.). This module replaces several different part numbers. As long as your vehicle is on the fitment list, this module will work for you.
Is there a core charge for my old part?
There is no core charge for this part. You can keep or recycle your old module without needing to send it back to us.
