An Expert’s Note on Vehicle Downtime
“I once worked with a plumbing contractor whose ’01 Express 3500 started shifting so hard he was afraid to drive it. The transmission shop quoted him over $3,000 for a rebuild. On a hunch, we checked the PCM data and found communication errors. We swapped in a pre-programmed module just like this one, and the van drove perfectly. That simple fix saved him thousands of dollars and, more importantly, got his fully-stocked work van back on the job in under an hour. Never underestimate the brain of the operation.”
Don’t let a faulty computer dictate your schedule. By providing us with your VIN upon purchase, you are ordering more than just a part; you are ordering a complete solution. This programmed 16263494 PCM is the key to restoring your vehicle’s reliability and your own peace of mind.
Frequently Asked Questions
What do I need to do after I purchase this PCM?
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.
Will I need to do any extra programming after installation?
No, the core engine and transmission programming is complete. However, on many GM vehicles of this era, you may need to perform a simple security relearn procedure (often called Passlock or VATS) and a Crankshaft Variation Relearn (CASE relearn). These procedures do not require a dealer and can typically be done with basic tools or a capable scanner.
How can I be sure this part number is correct for my vehicle?
The best method is to check the part number on your original module. However, our comprehensive fitment list is highly accurate. Providing your VIN when you order allows us to double-check and guarantee you receive the correctly prepared and programmed 16263494 PCM for your exact vehicle configuration.
Will this fix my check engine light?
If your check engine light is caused by an internal failure of the original PCM, then yes, this part will resolve the issue. It’s crucial to properly diagnose your vehicle first to ensure the problem isn’t a faulty sensor or wiring issue elsewhere.
What’s the difference between a PCM, ECM, and ECU?
The terms are often used interchangeably. ECM (Engine Control Module) typically just controls the engine. A PCM (Powertrain Control Module) controls both the engine and the automatic transmission. For the vehicles this part fits, PCM is the most accurate term.
How difficult is the installation?
On most of these trucks and vans, the PCM is located in the engine bay and is easily accessible. The physical installation involves disconnecting the battery, unplugging a few electrical connectors, and unbolting the module. It’s a job most DIY mechanics can handle in under an hour.
