Restore Your Bravada’s Performance & Reliability
Is your Oldsmobile Bravada, Envoy, or Trailblazer suffering from baffling electrical issues, poor performance, or a dreaded no-start condition? A failing Powertrain Control Module (PCM) is often the culprit behind these frustrating problems.

An Expert’s Note on PCM Replacement
As a technician, I’ve seen countless vehicle owners waste time and money on junkyard computers. While it seems like a cheap fix, a used PCM from another vehicle will not work without proper programming. It contains the wrong VIN and security information, which will prevent your Bravada from starting due to the anti-theft system. Our service eliminates that entire headache. We use professional tools to load your exact VIN and the correct software, making the installation process as simple as possible for the DIY mechanic or professional shop. This is the correct way to replace a 2003-2004 Oldsmobile Bravada PCM and ensure a lasting, reliable repair.
Frequently Asked Questions
Is this module truly plug-and-play?
Yes, it is pre-programmed to your VIN. However, like any GM PCM replacement of this era, you will need to perform a simple security relearn procedure so the module recognizes your keys. This typically takes about 30 minutes and requires no special tools, just your ignition key.
How do I provide my VIN number?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We cannot ship your part until we receive this information, as it is essential for the programming process.
Do I need to send my old PCM back?
No, there is no core charge or requirement to return your old, faulty module. You can dispose of it as you see fit.
Will this fix my transmission shifting problems?
If the shifting issues are caused by faulty data or internal failure within the PCM, then yes, this part will resolve them. However, it’s crucial to ensure the problem isn’t mechanical (like a bad solenoid or low fluid) before replacing the computer. This part corrects electronic and software-based faults.
My part number isn’t 16255757, but it’s on your list. Will it work?
Absolutely. The part numbers listed (12573576, 12574976, etc.) are all hardware-compatible and interchangeable. We program the correct software for your specific vehicle based on the VIN you provide, regardless of the original part number.
