Is Your Vehicle Running Rough? Get Back on the Road with Confidence.
There’s nothing more frustrating than a car that won’t cooperate. If you’re dealing with a persistent check engine light, erratic shifting, a rough idle, or even a no-start condition, the problem often points directly to a failing Powertrain Control Module (PCM). This isn’t just a part; it’s the brain of your vehicle, and when it falters, the entire system suffers. This replacement PCM is the reliable, straightforward solution to restore your car’s performance and your peace of mind.
Common Symptoms & Your Solution
A failing PCM can manifest in numerous ways, leaving you guessing. If you’re experiencing any of the following, this module is your answer:
- Check Engine Light (CEL): Often with communication error codes like P0601, P0605, or U-codes.
- Poor Performance: Noticeable loss of power, decreased fuel economy, and hesitation during acceleration.
- Transmission Issues: Harsh or delayed shifting, or getting stuck in one gear (limp mode).
- No-Start Condition: The engine cranks but refuses to start, often due to no fuel injector pulse or spark control.
- Failed Emissions Test: Inability to pass smog or emissions testing due to internal module faults.
By replacing your old unit with this pre-programmed 1998 Buick Regal PCM, you are directly addressing the root cause of these issues and installing a component that ensures your engine and transmission operate exactly as the manufacturer intended.

An Expert’s Note on Installation
As a technician, I’ve seen countless issues arise from improperly matched computers. Ordering a generic, un-programmed module often creates more problems than it solves. Our process of programming the 1998 Buick Regal PCM to your specific VIN is the most critical step. It ensures the transmission shift points, fuel trims, and anti-theft system (if applicable) are all correctly calibrated. After installation, you will need to perform a simple security relearn procedure, which can typically be done without special tools. This final step is key to a successful, long-lasting repair that lets you truly trust your vehicle again.
Don’t let a faulty computer keep you off the road. This is the correct, reliable fix to get your car running right. By providing us with your VIN upon purchase, you ensure that the 1998 Buick Regal PCM you receive is perfectly tailored to your vehicle’s specific configuration, making the repair process as smooth as possible.
Frequently Asked Questions
How does the programming process work?
After you complete your purchase, you will need to send us your vehicle’s 17-digit VIN. Our technicians use this number to access the official GM database and load the correct, updated software onto the module. This ensures it is a perfect match for your car’s engine, transmission, and options.
Do I need to send my old PCM (core) back?
No core charge or return is required for this part. You can keep or responsibly dispose of your old module.
Is any additional programming needed after installation?
While the main engine and transmission programming is complete, you will likely need to perform a security relearn procedure (often called a VATS relearn) to sync the module with your vehicle’s keys. This process typically takes about 30 minutes and can be done at home without any special scan tools. Instructions are widely available online for your specific model.
How can I be sure this part will fit my vehicle?
This PCM is compatible with a wide range of GM models from 1998-1999 as listed in the description. The most important step is providing your VIN. As long as your vehicle is on the compatibility list, our VIN-based programming guarantees it will be the correct computer for your car.
What if my original part number isn’t listed?
The service numbers provided (e.g., 09356741, 16236757) cover many original part numbers. If you are unsure, please contact us with your VIN before ordering, and we can verify compatibility for you.
