Restore Your Vehicle’s Performance and Reliability
Are you struggling with a persistent Check Engine Light, unpredictable stalling, or poor engine performance in your GM vehicle? A failing Powertrain Control Module (PCM) is often the culprit behind these frustrating and complex issues. This isn’t just an inconvenience; it affects your vehicle’s reliability, fuel economy, and overall driving experience. We offer the definitive solution: a professionally programmed PCM that gets you back on the road with confidence.

An Expert’s Note on VIN Programming
As a technician with over 20 years of experience, I can’t stress this enough: proper VIN programming is not optional. It’s the critical step that tells the module about your car’s specific configurationโfrom the engine and transmission type to anti-theft systems and even tire size. A generic or improperly flashed module can lead to a no-start condition or a cascade of new error codes. We handle this complex process for you, ensuring the 1998 Monte Carlo PCM 9356741 you receive is a perfect match, saving you time, money, and immense frustration.
Frequently Asked Questions
Do I need to do any programming or flashing myself?
No. This PCM is sold as a plug-and-play solution. We flash the unit with the latest GM software using the VIN you provide, so it’s ready for installation as soon as you receive it.
How do I provide my vehicle’s VIN?
After you complete your purchase, simply send us a message with your 17-digit Vehicle Identification Number (VIN). You can also add it as a note during the checkout process. We cannot ship your part until we have this information.
My original part number is different. Will this still work?
Yes, as long as your original part number is on our compatible service number list (e.g., 16236757, 9357034). This single unit is designed to supersede and replace a range of original part numbers for the listed GM vehicles.
Will I need to perform a CASE Relearn procedure?
In some GM vehicles, a Crankshaft Variation (CASE) Relearn procedure is recommended after replacing the PCM to prevent a P1336 trouble code. This procedure requires a compatible professional scan tool and calibrates the new module to the engine’s crankshaft position sensor for optimal timing and misfire detection.
Is this the correct part for my vehicle?
This 1998 Monte Carlo PCM 9356741 fits a wide range of GM models from 1998-1999, including the Grand Prix, LeSabre, Lumina, and many others. Please review the detailed fitment list in our description to confirm compatibility with your specific make, model, and engine.
