JASPER Engines & Transmissions

“Give Your Vehicle a New Lease on Life with JASPER.”

If you have a big oil slick in your driveway or get strange noises from under your hood that does not have to mean you will be saddled with a new car payment soon. Instead, Auto Pro can drop in a completely remanufactured JASPER domestic or import engine, transmission or differential and get back on the road again quickly!

JASPER also offers a full line of transfer cases for both 4 wheel drive and all wheel drive applications. Most popular models are in stock for immediate availability and come with a 36 month/100,000 mile Nationwide Transferable Warranty — Parts and Labor. Off-road applications receive an 18 month/75,000 mile parts and labor warranty.
