Expert Insight: The Heartbeat of Your GM Vehicle
Many of the vehicles this PCM fits, like those with the legendary 3800 Series II V6, are known for their incredible durability. They are workhorses that can run for hundreds of thousands of miles. However, after two decades of heat cycles and electrical demands, the original PCM is often the first major electronic component to fail. It can cause baffling problems that seem unrelated, from transmission woes to engine misfires. Replacing the PCM with a properly programmed unit like this one is often the final step in restoring that legendary GM reliability and ensuring your vehicle has many more years of service ahead. This is more than a repair; it’s an investment in your vehicle’s long-term health.
Frequently Asked Questions
Do I need to do anything after I install it?
This module is programmed to be plug-and-play. In some GM vehicles, a straightforward security relearn procedure (often called a Passlock or VATS relearn) may be necessary. This procedure is simple, requires no special tools, and instructions can be easily found online or in your vehicle’s service manual.
How do I provide my vehicle’s VIN?
After you complete your purchase, simply send us a message with your 17-digit VIN. We cannot program and ship your part without it. Please double-check the VIN for accuracy before sending.
Is this a new part?
No, this is a high-quality, used OEM part sourced from a salvaged vehicle. Each unit is thoroughly inspected and tested before being programmed. This allows us to provide a reliable, factory-correct part at an excellent price.
Will this fix my transmission shifting problems?
In many cases, yes. The PCM (also known as the ECU or ECM) controls both the engine and the transmission. Faulty signals or internal failures in the PCM are a very common cause of harsh shifting, delayed engagement, or other transmission issues. Replacing a faulty 1999 Buick Century PCM 09361735 often resolves these electronic-based transmission problems.
What if my original part number is slightly different?
This listing is specifically for part number 09361735. While GM sometimes uses interchangeable numbers, it is crucial to match the part number from your original module to ensure compatibility. Please verify your old part number before ordering.
