Restore Peak Performance to Your Classic Cadillac
Is your Cadillac Eldorado, DeVille, or Seville suffering from frustrating and unpredictable electronic issues?

Expert Insight: The Heart of Your Northstar
The PCM in these mid-90s Cadillacs is more than just an engine computer; it’s the central nervous system for the legendary Northstar V8 and the 4T80-E transmission. It manages a complex web of data from dozens of sensors to control fuel delivery, spark timing, and shift points with precision. This is why a generic, non-programmed module from a salvage yard simply won’t work. Our VIN-specific programming ensures that the computer’s logic perfectly matches your car’s unique configuration, from its gear ratios to its specific emissions equipment, reviving its true character.
By choosing this expertly prepared 1996-1999 Cadillac Eldorado PCM, you’re not just buying a part; you’re investing in a reliable and complete solution that will have your classic luxury car running its best for years to come. This module is also the correct fit for the Oldsmobile Aurora and other Cadillac models listed, providing the same level of restoration.
Frequently Asked Questions
Why do you need my VIN?
Your Vehicle Identification Number (VIN) is essential because it contains specific information about your car’s engine, transmission, and factory options. We use the VIN to load the exact GM-certified software your vehicle requires, ensuring perfect compatibility and preventing any system conflicts.
Is any additional programming required after installation?
No. This PCM is shipped fully programmed and ready for installation. In most cases, it is a true plug-and-play solution. You will not need to take it to a dealer or mechanic for further programming.
Will this fix my Check Engine Light?
If the Check Engine Light is caused by a faulty PCM or related communication errors, this part is the correct solution. However, it’s always recommended to have your vehicle scanned for codes to ensure there aren’t other underlying issues, such as a bad sensor, that also need to be addressed.
Is this part difficult to install?
The PCM on these models is typically located in the engine compartment or under the dash and is held in place by a few bolts with electrical connectors. For someone with basic mechanical skills, it is a straightforward process. Always remember to disconnect the battery before beginning the installation.
