Is Your Truck or SUV Running Rough, Stalling, or Showing a Check Engine Light?
Dealing with erratic engine behavior in your Oldsmobile Bravada, Chevy S10, or GMC Jimmy can be incredibly frustrating. When the very brain of your vehicle—the Powertrain Control Module (PCM)—starts to fail, it can cause a cascade of confusing problems, from poor fuel economy and harsh shifting to a complete no-start condition.

Expert Technician’s Insight: After 20+ years on the road, the circuit boards inside these original PCMs experience thousands of heat cycles. We often see microscopic cracks develop in the solder joints for the main processor or the voltage regulation circuits. This leads to intermittent connections that cause the bizarre, hard-to-diagnose symptoms you’re likely facing. Our modules have been thoroughly inspected and validated to ensure these critical connections are solid, providing a dependable, long-term fix. It’s not just a replacement part; it’s a restoration of your vehicle’s core reliability.
Don’t let a faulty computer keep your trusty truck or SUV off the road. This is your opportunity to fix it right the first time. By providing us with your VIN upon purchase, you ensure that the 1999 Oldsmobile Bravada PCM you receive is perfectly matched to your vehicle. This attention to detail is what separates a quick fix from a proper, long-lasting repair.
Frequently Asked Questions
Do I need to do anything after installing the PCM?
In most cases, this is a plug-and-play installation. However, on some GM vehicles of this era, a security relearn procedure (often called Passlock or VATS) may be required. This is a simple procedure that takes about 30 minutes and involves cycling the key. Instructions are readily available online, and it does not require any special tools.
How do I provide my VIN?
After you complete your purchase, simply send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot program and ship your module without it. You can find your VIN on your vehicle’s dashboard (visible through the windshield) or on your registration and insurance documents.
Is this compatible with other part numbers?
Yes, this unit is a direct replacement for several part numbers, including 16263494, 8162634940, 218-11787, and 21811787. As long as your vehicle is on the compatibility list, this module will work correctly once programmed to your VIN.
What if this doesn’t fix my problem?
While this programmed 1999 Oldsmobile Bravada PCM is the definitive solution for the symptoms listed, proper vehicle diagnostics are always recommended. If the module does not resolve your issue, it’s possible there is another underlying problem with wiring, sensors, or other components. We are committed to your satisfaction and can help guide you on potential next steps.
Will this fix my transmission shifting issues?
Yes, in many cases it will. The PCM (also known as the ECM or ECU) controls both the engine and the automatic transmission. Faulty data or internal processing errors can directly cause harsh shifting, delayed engagement, or incorrect gear selection. Restoring proper PCM function often resolves these transmission-related complaints.
