Restore Peak Performance to Your GM Vehicle
Is your late-90s GM car or van running rough, shifting erratically, or struggling with a persistent Check Engine light? A failing Powertrain Control Module (PCM), the vehicle’s main computer, is often the hidden culprit behind these frustrating and complex issues. This module is the direct-fit, reliable solution to restore your vehicle’s brain to perfect working order, getting you back on the road with confidence.
Common Symptoms & Your Solution
A faulty engine computer can cause a wide range of problems that can be difficult to diagnose. If you’re experiencing any of the following, this part is your definitive solution:
- Poor or erratic engine performance
- Harsh or incorrect automatic transmission shifting
- Reduced fuel economy
- Intermittent stalling or no-start conditions
- Check Engine Light with PCM-related codes (e.g., P0601, P0602, P0605)
- Failure to communicate with diagnostic scan tools
Instead of struggling with a problematic original unit, you can solve the problem correctly with our professionally Programmed 16236757 PCM. We flash the module with the latest GM software updates using your vehicle’s specific VIN, ensuring it works seamlessly with your car’s unique configuration.

Expert Technician’s Insight
As a technician with over two decades of experience, I’ve seen countless hours and dollars wasted on these specific GM platforms. Drivers often replace perfectly good sensors, solenoids, or even entire transmissions chasing a ghost, when the root cause was a failing PCM driver circuit. The computers in these 3.1L, 3.4L, and 3.8L cars are known to develop internal faults that create bizarre symptoms. By providing us with your VIN, you’re not just getting a part; you’re getting a module with the exact software calibration for your vehicle’s options, ensuring every system communicates as the factory designed it to.
Frequently Asked Questions
What is a VIN and why do you need it?
The VIN, or Vehicle Identification Number, is your car’s unique 17-digit serial number. We require it to load the exact, factory-correct software for your specific engine, transmission, emissions equipment, and other options. This step is critical for a true plug-and-play installation.
Do I need to do anything after I install this PCM?
In most cases, the module is ready to go right out of the box. However, some vehicles may require a Crankshaft Variation Relearn (also known as a CASE relearn) to prevent a P1336 trouble code. This procedure can be performed by most professional scan tools and helps the new computer fine-tune its readings for the smoothest operation.
Will this fix my transmission shifting problems?
If your shifting issues are caused by faulty electronic commands from the computer, then yes, this Programmed 16236757 PCM is the correct solution. The PCM directly controls transmission line pressure and shift solenoid operation.
Is this a new or used part?
This is a genuine OEM module that has been meticulously inspected, tested, and prepared by our expert technicians to meet or exceed original factory performance specifications, ensuring reliability and longevity.
How long does the programming process take?
Once you provide your VIN after purchase, programming is typically completed within one business day. We perform this service before the part is shipped to you, so it arrives ready for installation.
