Jasper Engines And Transmissions - So the nightmare begins
Cheap gaskets in installation kits. 30 thousand miles and a leaking oil cooler gasket. Low and behold not covered under warranty. I have never heard of a gasket failing this fast. Theory is cheap part. Now out 6 hours in labor to replace it.
Last year I took My 1999 F-350 with 186k on it’s 7.3 Power Stroke Diesel in to Bills Garage in Taylor MI. It took until April to get a Jasper engine and until Almost July to finally get it done. The replacement is knocking louder and has less power and performance than...Read more
Well it had been quite a few years since I had tried Jasper Injectors. The injector wiring off the injector had bare wires that could touch and short out. So my sales guy kept telling me about all the updates that they do and how great they are so we bought 8...Read more
I didn't like
- Quality of parts and customer service
Back in 2011, I had a Jasper transmission installed in my 2005 Ford E-250 van with a 5.4 liter engine. I was working at the time and had the work done in Virginia (I lived in Michigan) and the mechanic was unknown to me. I still run the vehicle with 730,000 miles on...Read more
I purchased the transmission from American Pride in York County, VA. An authorized Jasper dealer. The original transmission was slipping in reverse after 87k miles. All other gears worked fine. I paid an extra 1000 for a total of 4800 to install a Jasper replacement to...Read more

Jasper Engines And Transmissions - Warranty scams
Replaced engine after 6k miles because fuel injector pump exploded. Jasper sent the motor but would not cover install cost. Jasper said water in fuel caused part to fail. As a certified mechanic myself and 2nd opinions. This would be 1 chance in a million cause. Jasper would not look at injectors themselves to verifie finding. Out 2250 for install and 6500 for 2 weeks expenses in CA. +lost wages

Jasper Engines And Transmissions - Leaks oil from every seal and o ring
From intial install leaked oil and fuel from every fitting. Replaced every o ring on the Injectors. Every oil seal. Front seal 4 times. Not jasper fault their seal but they didn't install. 2700 miles leaking oil like the valdez. Shop says rear main only seal that hasn't been changed. Pan bolts were all loose missing two bolts. Rear main should be replaced tomorrow will see if warranty pays and leaks are cured. Would not recommend this motor. 2001 dodge Cummins 5.9

Don't waste your time and money. Bought a Ford Triton engine, Failed in the first 6 months and less then 20,000 miles. They would not take care of the warranty. I had to pay upfront to have it removed and then installed again. Jasper would only pay if they found that...Read more
