Is Your Vehicle Running Rough, Stalling, or Refusing to Start?
Dealing with erratic engine behavior in your daily driver can be incredibly frustrating and stressful. Whether it’s a persistent Check Engine Light, poor fuel mileage, harsh shifting, or a no-start condition that leaves you stranded, the root cause is often a failing Powertrain Control Module (PCM). This isn’t just an inconvenience; it’s a critical issue that affects your vehicle’s performance, safety, and reliability. You need a solution that is both effective and straightforward, getting you back on the road without the hassle and expense of a dealership visit. The 1998 GM PCM 9356741 is that definitive solution.
Common Symptoms & Your Solution
If you’re experiencing any of the following, a faulty PCM is the likely culprit:

- Rough or unstable idling
- Noticeable decrease in fuel economy
- Hesitation or stumbling during acceleration
- Harsh or erratic automatic transmission shifting
- Engine stalling or complete failure to start

Expert Insight: The Junkyard Gamble vs. A Sure Thing
As a technician, I’ve seen countless drivers try to save a few dollars by pulling a computer from a salvage yard. It almost never ends well. You might get a module from a vehicle with different options, a different final drive ratio, or even a different security system (VATS/Passlock). This leads to a no-start condition that can be incredibly difficult to diagnose. You end up spending more on diagnostic fees and towing than you would have on the correct part in the first place. This 1998 GM PCM 9356741 is programmed specifically for your vehicle, eliminating all of those compatibility and security headaches. It’s the smart, professional repair that saves you time and money in the long run.

Frequently Asked Questions
Do I need to do any programming after I receive this part?
No. This is the primary benefit of our service. We program the module to the VIN you provide before shipping it. It will arrive ready for you to install, making it a true plug-and-play solution. In some GM vehicles, a simple security relearn procedure may be necessary, which takes 10-30 minutes and does not require any special tools.
How do I provide my VIN?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). You can typically add it as a note during checkout or send it to us in a message referencing your order number. We cannot ship your part until we receive the VIN.
Is this a new or used part?
This is a professionally prepared, tested, and verified original equipment part. Each unit undergoes a thorough inspection and programming process to ensure it meets or exceeds factory specifications for performance and reliability.
Will this fix my transmission shifting problems?
In many cases, yes. The PCM controls the electronic solenoids in the transmission that manage shifting. If the computer is sending faulty signals, it can cause harsh shifts, delayed engagement, or slipping. Replacing a bad PCM often resolves these issues, provided the transmission itself is mechanically sound.
What if my part number isn’t an exact match to 9356741?
Please check the list of compatible service numbers provided in the description (09356741, 16236757, 9357034, etc.). GM often uses multiple part numbers for the same component. As long as your original part number is on our cross-reference list, this unit will be a correct and compatible replacement for your vehicle.
