Expert Insight: The Brain Transplant for Your Car
As a technician, I’ve seen countless hours and dollars wasted chasing electronic gremlins. A customer brought in their ’98 LeSabre with a persistent misfire and harsh shifting that new plugs, wires, and sensors couldn’t fix. The root cause? The original PCM was failing internally. Installing a pre-programmed module like this one was like giving the car a new brain. Not only did it fix the primary complaints, but the updated software also improved transmission behavior. This is the most direct way to solve complex control issues on these reliable, but aging, GM vehicles.

Frequently Asked Questions
Do I need to do any programming myself?
No. We program the module to your vehicle’s VIN before shipping. The only step you may need to perform is a simple security relearn procedure, which involves turning the key on and off and can be done in your driveway in about 30 minutes. We provide instructions for this process.
Where do I provide my VIN?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot ship your part until we have this information to ensure correct programming.
How do I know if this part will fit my vehicle?
This module, service number 16236757, fits a wide range of 1998-1999 GM vehicles as listed. The most reliable way to ensure a perfect match is by providing your VIN. We use it to load the exact software and calibration file for your specific make, model, and engine.
What is the security relearn procedure?
It’s a simple process required by GM’s anti-theft system (Passlock/Passkey) to recognize the new PCM. It typically involves cycling the ignition key for 10-minute intervals three times. This allows the Body Control Module and the new PCM to synchronize. Instructions are included.
Will this fix my transmission shifting problems?
In many cases, yes. The PCM also controls transmission functions like shift points and line pressure. If your original module is failing, it can cause erratic shifting. A new, correctly programmed 1998 Grand Prix PCM 16236757 with updated software can significantly improve transmission performance.
