Engine Repair Rebuild Replacement

Auto Pro is one of Maryland leaders in replacement of engines and rebuilt engines with ones made by JASPER.  Install a completely remanufactured JASPER gas engine in your vehicle and get the best of both worlds.

Remember, this is a completely remanufactured engine with all new wear parts, tight tolerances and run-tested reliability.

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.

Two Helpful Tips from the Maryland Department of Transportation to save Gasoline and reduce your Fuel Bill:

1. Maintain your Car

  • Get regular tune ups
  • Replace dirty air and fuel filters
  • Use proper grade of oil
  • Do not overfill your gas tank
  • Properly inflate your tires
  • Do not buy "aggressive" tread tires if your car does not require them

2. Use your car's engine wisely

  • Avoid excessive idling
  • Use cruise control on the highway
  • Shift up as quickly as possible when using a manual transmission
  • Run air conditioner when traveling over 40 mph (It is more efficient than with windows down)
