Restore Your GM Truck or Van’s Performance and Reliability
Is your trusty Chevrolet, GMC, or Isuzu suffering from frustrating issues like a persistent check engine light, rough idling, poor fuel economy, or even a no-start condition? A failing Powertrain Control Module (PCM) is often the hidden culprit behind these problems. This replacement PCM, compatible with service number 16263494, is the definitive, hassle-free solution to get your vehicle back on the road and running like it should. We take the guesswork out of the repair by professionally programming this module to your vehicle’s specific VIN, ensuring a perfect, plug-and-play installation right out of the box.
Common Symptoms & Your Solution
A faulty engine computer can wreak havoc on your vehicle’s systems, often leading to confusing symptoms and incorrect diagnoses. If you’re experiencing any of the following, a new Programmed 16263494 PCM is the most reliable fix:
- Persistent Check Engine Light (CEL)
- Diagnostic Trouble Codes (DTCs) related to internal module failure, such as P0601 or P0606
- Engine stalling, stumbling, or misfiring
- Harsh or erratic automatic transmission shifting
- Complete no-start condition with no communication to the module

Expert Insight from a 20-Year Technician
I can’t count how many times I’ve seen owners and even shops replace perfectly good sensors, spark plugs, and coils trying to solve an erratic misfire or a transmission that won’t shift right on these GM 4.3L and 5.7L engines. The real issue is often a failing computer that’s sending out bad signals. A failing PCM can cause a perfectly good transmission to shift hard or a healthy engine to run rough. This Programmed 16263494 PCM is the heart of the operation; by replacing it with a correctly programmed unit, you’re not just fixing one symptom, you’re restoring the entire system’s stability and preventing a cascade of other issues down the line. It’s the foundational fix that saves you time, money, and immense frustration.
Frequently Asked Questions
How does the programming process work?
After you place your order, you will need to provide us with your vehicle’s 17-digit Vehicle Identification Number (VIN). Our technicians use this VIN to load the exact, most current GM-approved software and calibrations for your specific make, model, and engine. This ensures the module works seamlessly with your vehicle’s existing systems.
Is this a true plug-and-play part?
Yes. Because we program the module to your VIN before shipping, it arrives ready for installation. In the vast majority of vehicles this part fits, you can simply disconnect the battery, swap the modules, and reconnect the battery. No further programming or special tools are required.
What information do you need from me?
We only need your complete 17-digit VIN. You can typically find this on your vehicle’s dashboard (visible through the windshield on the driver’s side), on the driver’s side door jamb sticker, or on your vehicle’s registration and insurance documents.
Will this fix my check engine light?
If the check engine light and associated trouble codes are caused by a faulty PCM (like internal processor errors), then yes, this part will resolve the issue. However, if the codes are for other failing components (like an oxygen sensor or EGR valve), those parts will still need to be addressed. This module will fix any issues originating from the computer itself.
How can I confirm this is the right part number for my vehicle?
The best way is to check the service number on your original module. It will have a sticker with a number like ‘16263494‘ or one of the other compatible part numbers listed. You can also use our comprehensive fitment list or contact us with your VIN, and we can verify compatibility for you.
