Expert Insight: As a technician with over 20 years of experience, I’ve seen countless hours wasted chasing symptoms caused by a failing PCM. A customer with a ’98 LeSabre came in with intermittent stalling and a transmission that shifted erratically after warming up. They had already replaced multiple sensors. We identified a failing PCM, installed one of our VIN-programmed units, and the car ran perfectly. The key is the programming—it ensures all the vehicle’s systems work in harmony from the moment you turn the key. This is why a pre-flashed Programmed PCM 9356741 is the smartest repair.
Frequently Asked Questions
Do I need to do any programming or flashing myself?
Absolutely not. This PCM is a complete plug-and-play solution. We handle all the programming to your specific VIN before we ship it. All you need to do is install it.
Where do I provide my vehicle’s VIN?
After you complete your purchase, we will contact you with simple instructions on how to provide us with your vehicle’s 17-digit VIN. We cannot ship your part until we receive this information.
How do I know if this is the right part for my car?
Please check the comprehensive compatibility list on this page. This module replaces several service numbers, including 09356741 and 16236757. If your vehicle and original part number are listed, this is the correct part for you.
Will this PCM require a security relearn procedure?
On many GM vehicles of this era, a simple security relearn procedure (often called a Passlock or VATS relearn) is required after installation. This procedure is straightforward, takes about 30 minutes, and can be done without any special tools. We include instructions to guide you through it.
Will this fix my specific check engine light code?
This Programmed PCM 9356741 is the guaranteed solution for internal module fault codes (e.g., P0601, P0605). If your check engine light is on for other reasons, such as a faulty sensor, you should diagnose and repair that issue first. A faulty PCM can sometimes cause false sensor codes, but it’s always best practice to rule out other components.
