Is Your 1996 GM Running Rough? Get Back on the Road with Confidence.
There’s nothing more frustrating than an engine that won’t cooperate. If your trusted Buick, Pontiac, or Oldsmobile is suffering from stalling, a persistent check engine light, or 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’s engine and transmission. We provide the definitive solution: a reliable, professionally programmed PCM that restores your vehicle’s performance and gets you driving with peace of mind.
Common Failure Symptoms & Your Direct-Fit Solution
A faulty engine computer can mimic a dozen other problems, leading to expensive and incorrect repairs. If you’re experiencing any of the following, a failing PCM is the likely culprit:
- Persistent Check Engine Light (CEL) with codes like P0601 (Internal Memory Error)
- Engine stalls unexpectedly or runs rough
- Difficulty starting or a complete no-start condition
- Poor fuel economy and sluggish performance
- Harsh or erratic automatic transmission shifting
- Failure to pass an emissions test
This isn’t a generic, off-the-shelf part. We flash this 1996 GM Programmed PCM with the latest GM software updates specifically for your car’s Vehicle Identification Number (VIN). This critical step ensures perfect communication between all vehicle systems, eliminating the need for an expensive trip to the dealership for programming.

From the Shop Floor: A customer brought in a ’96 Bonneville with an intermittent stalling problem that had them stumped for months. They had replaced multiple sensors with no luck. The issue was a thermally failing PCM that only acted up after 20 minutes of driving. Installing a quality 1996 GM Programmed PCM like this one not only solved the stalling instantly but also smoothed out the 1-2 shift, a common complaint fixed by the updated software. Proper diagnosis saves time, but the right part finishes the job.
Frequently Asked Questions
What do I need to do after I purchase?
After you complete your purchase, you must provide us with your vehicle’s 17-digit VIN. We cannot program and ship your module without it. You can typically add this as a note during checkout or send it to us in a message referencing your order number.
Is this part truly plug-and-play?
Yes, for engine and transmission operation. Because we program it to your VIN, it will start and run the vehicle correctly. However, on these 1996 GM models, you may need to perform a simple security relearn procedure (for the VATS/Pass-Key system) which takes about 30 minutes and requires no special tools. Instructions are widely available online.
How do I find my VIN?
Your VIN is located on a metal tag on the driver’s side of the dashboard (visible through the windshield) and on the driver’s side door jamb sticker. It is also found on your vehicle’s registration and insurance documents.
Will this fix my car’s specific issue?
This 1996 GM Programmed PCM will correct any issues directly caused by a faulty computer. While the symptoms listed above are common indicators of PCM failure, we always recommend a thorough diagnosis by a qualified technician to confirm the PCM is the root cause of your problem before ordering.
Does this unit come with a warranty?
Absolutely. This unit is backed by our one-year replacement warranty, offering you protection and peace of mind for your investment.
