Is Your Truck or Van Running Rough?
If your reliable GM workhorse is suddenly stalling, shifting erratically, or refusing to start, the problem often lies with a failing Powertrain Control Module (PCM). A faulty engine computer can cause a cascade of frustrating issues, leaving you stranded and costing you valuable time. Don’t let a bad module sideline your vehicle. This is the straightforward, reliable fix you need to get back on the road with confidence.
Common Failure Symptoms & Your Direct-Fit Solution
A failing PCM can manifest in many ways, often mimicking other sensor or component failures. If you’re experiencing any of the following, a faulty module is the likely culprit:
- Engine stalling or cutting out intermittently
- Harsh or unpredictable automatic transmission shifting
- Complete no-start condition where the engine cranks but won’t fire
- Persistent Check Engine Light (CEL) with communication error codes (like P0601, P0605)
- Poor fuel economy and reduced engine power
- Inability for a scan tool to communicate with the module
This fully programmed 9355699 PCM is the definitive solution. We take a reliable, tested OEM computer and flash it with the latest GM software updates specifically for your vehicle’s VIN. This ensures that all factory parameters for your engine, transmission, and accessories are perfectly matched, restoring the performance and dependability you count on.

An Expert’s Note on GM Security Systems
Many of the GM trucks and vans from this era use a Passlock or VATS security system that is tied directly to the PCM. This is why you can’t just swap in a module from another vehicle. The security data won’t match, and the vehicle will not start. Our VIN programming service correctly syncs the module to your vehicle’s specific systems, bypassing this common roadblock and ensuring a successful, stress-free installation.
Don’t let a bad computer keep your vehicle down. This programmed 9355699 PCM is your ticket to a fast, effective, and lasting repair. Order today and restore the heart of your GM truck or van.
Frequently Asked Questions
Do I need to do any programming myself?
No. This PCM comes fully programmed to the VIN you provide during checkout. In most cases, it is a plug-and-play installation, though some vehicles may require a simple, key-on/key-off security relearn procedure that takes about 30 minutes and requires no special tools.
What information do you need from me?
After you place your order, we will need the 17-digit Vehicle Identification Number (VIN) from your truck or van. You can typically find this on your driver’s side dashboard (visible through the windshield) or on the sticker in the driver’s side door jamb.
Is this a new part?
No, this is a thoroughly tested, used OEM (Original Equipment Manufacturer) computer sourced from a salvaged vehicle. This ensures you get a genuine GM part with proven durability at a great value.
Will this fix my check engine light?
If the check engine light is on due to an internal fault within your original PCM (such as code P0601), then this part will solve the problem. It is crucial to properly diagnose your vehicle to ensure the PCM is the root cause of your issues before ordering.
How can I be sure this fits my vehicle?
This module replaces service ID 9355699 and a range of other part numbers. The best way to confirm fitment is to check the part number on your original computer and compare it to the list in our description. If you are unsure, please provide us with your VIN, and we can verify compatibility for you.
