An Expert Mechanic’s Tip
Before you replace your PCM, take a moment to double-check your vehicle’s battery terminals and primary ground connections. A loose or corroded ground wire can cause erratic voltage and mimic the symptoms of a failing computer. Cleaning the connection points at the battery, engine block, and chassis is a quick, free step that can save you a lot of diagnostic headaches. A solid foundation is key to reliable electronics.
Frequently Asked Questions
Do I need to send you my old computer?
No, there is no core charge or need to send in your old module. This is a direct purchase.
What information do you need from me?
After you place your order, you must provide us with your vehicle’s 17-digit Vehicle Identification Number (VIN). We cannot ship your 2004 Savana 2500 PCM 89017739 until we have this information to program it correctly.
Is this part difficult to install?
The physical installation is straightforward for anyone with basic mechanical skills. It involves disconnecting the battery, unplugging the electrical connectors, and unbolting the old module.

Instructions can be readily found online for your specific vehicle.
Will this fix my specific problem?
This PCM is a direct solution for failures within the computer itself, which cause a wide range of engine and transmission issues.
