Restore Peak Performance to Your GM Truck or Van
Is your dependable Chevy or GMC truck sidelined by frustrating electrical issues? A faulty Powertrain Control Module (PCM) can cause everything from a no-start condition and poor fuel economy to erratic shifting, leaving you stranded and costing you valuable time. This professionally programmed PCM is the definitive, plug-and-play solution to get your vehicle running reliably again, fast.
Common Symptoms & Your Solution
If you’re experiencing a combination of the following issues, a failing PCM is the most likely culprit. This module is engineered to resolve these problems by restoring the critical link between your vehicle’s engine and transmission.
- Persistent Check Engine Light (CEL)
- Engine misfires or rough idle
- Poor acceleration and loss of power
- Reduced fuel economy
- Harsh or incorrect automatic transmission shifting
- Complete no-start condition where the engine cranks but won’t fire
- Communication error codes (U-codes) with scan tools
Installing our Programmed 16263494 PCM is the most effective way to permanently fix these issues. We take the guesswork out of the repair by flashing the module with your vehicle’s specific VIN and the latest GM software before it even ships.

A Veteran Technician’s Insight: For over 20 years, I’ve seen these GM workhorses come in with all sorts of confusing symptoms. More often than not, the root cause is a failing PCM. The old ‘black box’ loses its mind, causing phantom misfires or transmission issues that mechanics chase for days. Swapping in a properly Programmed 16263494 PCM isn’t just a repair; it’s like giving the truck’s central nervous system a fresh start. This isn’t just about fixing a Check Engine Light; it’s about restoring the core dependability you rely on every single day.

Frequently Asked Questions
How do I provide my VIN number?
After you complete your purchase, you will receive an email with instructions on how to send us your vehicle’s 17-digit VIN. You can also add it to the ‘notes’ section during checkout. We cannot program and ship your module without the correct VIN.
Will I need to do anything after installing this PCM?
In many cases, this is a plug-and-play installation. However, some GM vehicles of this era may require a Security Relearn Procedure and/or a Crankshaft Position Sensor Relearn. These are simple procedures that can be done without a scan tool and instructions can be found online or in a service manual.
How do I confirm my old PCM is the problem?
First, check all fuses and ensure your battery and alternator are in good condition. If the vehicle has multiple symptoms like a no-start, erratic shifting, and communication codes, the PCM is a very likely cause. A definitive diagnosis can be made by a qualified technician, but replacing the PCM is a common and effective repair for these issues.
Is this a brand new module?
This is a high-quality replacement Powertrain Control Module that has been thoroughly inspected and tested to ensure it meets or exceeds original equipment specifications. It is loaded with the latest GM software for your vehicle to provide optimal performance and reliability.
Will this fix my specific Check Engine Light code?
This module is designed to correct a wide range of diagnostic trouble codes related to engine management, transmission control, and module communication. If the code points to a faulty computer or internal processor error, this Programmed 16263494 PCM is the correct solution.
