From the Technician’s Bench
As a veteran tech, I’ve seen countless GMT800 trucks and SUVs sidelined by a bad PCM. The symptoms are often misdiagnosed as failing sensors or a bad transmission, leading to expensive, unnecessary repairs. A tell-tale sign is the dreaded P0601 code (Internal Control Module Memory Check Sum Error), which is a definitive confirmation of internal failure. This pre-programmed unit is the exact solution I’d use in my own bay. It eliminates the guesswork and gets the vehicle running right, just as the factory intended, ensuring a successful repair on the first try.

Frequently Asked Questions
What information do you need from me after I order?
After you complete your purchase, you will need to provide us with your vehicle’s 17-digit VIN (Vehicle Identification Number). This is essential for us to program the module correctly for your specific vehicle configuration and options.
Is any additional programming required after installation?
In most cases, no. Our programming handles the core functions. However, on some GM vehicles, a simple Security Relearn procedure (which you can do yourself) may be needed to sync the module with your key. In some instances, a CASE (Crankshaft Angle Sensor Error) relearn with a scan tool may be required to turn off the check engine light, but the vehicle will run and drive without it.
How do I know for sure that my PCM is the problem?
While the symptoms listed above are strong indicators, the best way to be certain is with a proper diagnosis from a qualified mechanic. A diagnostic code like P0601 (Internal Control Module Memory Check Sum Error) is a definitive sign of PCM failure. This part is the solution for a confirmed faulty module.
Will this fix my transmission shifting problems?
Yes, in many cases it will. The PCM is also the transmission control module (TCM) in these vehicles. It controls shift points, line pressure, and torque converter lockup. If the module is faulty, it can cause a wide range of shifting abnormalities which this replacement part will correct.
Where is the PCM located on my vehicle?
On most of the trucks and SUVs listed, such as the Silverado, Tahoe, and Yukon, the PCM is located in the engine bay on the driver’s side, under or next to the battery tray. On models like the Trailblazer or Envoy, it is typically located next to the air filter box.
