Is Your Truck or SUV Running Rough?
There’s nothing more frustrating than a vehicle you can’t rely on. If your GMC Yukon, Chevy Silverado, or other GM truck is suffering from a persistent Check Engine Light, erratic shifting, a rough idle, or even a no-start condition, the problem often points directly to a failing Powertrain Control Module (PCM). Don’t let a faulty computer keep your dependable workhorse off the road. This is the straightforward, reliable solution to restore your vehicle’s performance and your peace of mind.
Common Symptoms & Your Direct-Fit Solution
A failing PCM can cause a host of confusing issues. You might be experiencing one or more of the following:
- Check Engine Light (CEL) with communication-related codes like P0601, P0602, or P0606.
- Engine Performance Problems: Stalling, hesitation, rough idling, or a sudden drop in fuel economy.
- Transmission Issues: Harsh or delayed shifting, or getting stuck in one gear.
- No-Start Condition: The engine cranks but won’t start, even with a good battery and starter.
- Failed Emissions Test: Inability to pass smog checks due to persistent fault codes.

An Expert’s Insight on PCM Failure
As a technician with over two decades of experience, I’ve seen countless GMT800-platform trucks and SUVs come into the shop with these exact symptoms. The original PCMs are tough, but after years of heat cycles under the hood and constant vibration, the internal solder joints and processors can begin to fail. It often starts as an intermittent issue—a weird shift here, a random stall there—before becoming a persistent headache. Replacing the unit with a correctly flashed module like this Programmed GM PCM 28042802 isn’t just swapping a part; it’s installing a fresh brain with updated logic that gets these legendary trucks back to work, day in and day out.
Frequently Asked Questions
What do I need to do after installing this PCM?
In most cases, you will need to perform a simple security relearn procedure (also known as a CASE relearn). This can typically be done without special tools and involves a sequence of key turns. Instructions are readily available online for your specific model, or your mechanic can perform it in minutes.
How do I provide my vehicle’s VIN?
Simply enter your 17-digit Vehicle Identification Number (VIN) in the designated field on the checkout page. We cannot program and ship your module without it, so please double-check it for accuracy.
Is this the correct part for my truck?
This PCM is compatible with a wide range of GM vehicles. Please review the detailed fitment list on this page and match the service number (e.g., 28042802, 12602802) to your original unit. If you’re unsure, contact us with your VIN, and we’ll be happy to verify compatibility.
What causes a PCM to fail?
The most common causes are heat, vibration, and age. Over time, these factors can cause internal electronic components and connections to degrade. Voltage spikes from a bad alternator or improper jump-starting can also damage the module.
Will this fix my Check Engine Light?
If the Check Engine Light is caused by an internal PCM fault (like a P0601 code), this replacement will solve the issue. However, if the light is on due to a faulty sensor or another component on the vehicle, that separate issue will still need to be addressed.
What is the warranty on this part?
This unit is backed by our one-year replacement warranty, giving you confidence in your purchase.
