Is Your GM Vehicle Running Rough? Get Back on the Road with Confidence.
There’s nothing more frustrating than a truck or SUV that won’t run right. Whether you’re dealing with a persistent check engine light, erratic shifting, stalling, or a complete no-start condition, a faulty Powertrain Control Module (PCM) is often the culprit. This computer is the brain of your vehicle, and when it fails, it can cause a cascade of confusing problems. This replacement PCM is the reliable, straightforward solution to restore your vehicle’s performance and get you back to your life without the guesswork.

Expert Insight: The Key to a Successful Install
As a technician, I’ve seen countless jobs go sideways because of a simple missed step. With this Programmed 12200411 PCM, we’ve done the heavy lifting by flashing it to your VIN. However, on many GM vehicles of this era, a final “CASE Relearn” (Crankshaft Position System Variation Learning) procedure is required after installation. This quick procedure, which can be done with most professional-grade scan tools, synchronizes the new PCM with your engine’s crankshaft position sensor. Skipping it can result in a P1336 trouble code. Ensuring this final step is done is the key to a smooth, trouble-free repair and getting your vehicle back to 100%.
Frequently Asked Questions
What information do you need from me?
After you place your order, you must provide us with your vehicle’s 17-digit Vehicle Identification Number (VIN). This is essential for us to program the PCM correctly for your specific vehicle configuration.
Is any additional programming required after installation?
Our programming covers all the essentials to get your vehicle running. However, as mentioned in our Expert Insight, many GM vehicles require a Security Relearn and a Crankshaft Position Variation (CASE) Relearn procedure after the new PCM is installed. These are simple procedures that can be done with a capable scan tool or by following specific key-on/off sequences.
How do I know if this is the correct part for my vehicle?
Please check the extensive fitment list on this page. The most reliable way is to match the service number on your original PCM. This module replaces part numbers 12200411, 12201281, 12576160, and 52369718. If you are unsure, please contact us with your VIN before ordering.
Where is the PCM located on my vehicle?
On most GM trucks and SUVs like the Sierra, Silverado, and Tahoe, the PCM is located on the driver’s side of the engine bay, under or near the battery tray. On vans like the Express and Savana, it’s often in the LH rear of the engine compartment. Always disconnect the battery before attempting removal or installation.
Will this fix my transmission shifting problems?
In many cases, yes. The PCM controls both engine and transmission functions. If your shifting issues are caused by faulty electronic signals or logic within the module, this replacement Programmed 12200411 PCM is the correct solution. However, it will not fix internal mechanical failures within the transmission itself.
