Do not purchase from this company. Years ago they were great, had a quality product and stood behind what they sold. In the last couple years their quality has gone down and their so called tech support has you perform tests to prove product has failed and when sent back they state there is nothing wrong and deny claims. Have reached out to field rep and asked for upper management to return calls and no contact.

Absolutely terrible company. Workmanship is atrocious and the warranty is a joke. Stay far far away from this company at all cost.

I have to tell you. I was not sure about replacing my engine on my ford. I talked to Randy at Jasper Engines usa. He took the time to answer all my questions. I even called him back 3 times and talked with me. Gave me no pressure. Jasper is a outstanding company.

OK so I had a local shop (Brothers 4X4) purchase a Jasper engine, after they installed it, it smoked every time I started it up. Jasper had the shop run tests and finally changed out the PCV valve. Drove it another 1,000 miles still smoked. Finally a new engine was ordered because one of the cylinders was leaking oil into my exhaust. So after several trips back and forth to get my jeep diagnosed and fixed, costing me several hundred dollars in tows and time it now has a new engine. this one smoke at startup much less than the previous one I believe maybe there is residual oil from the first engine. But my concern and worry is how has this effected my catalytic converters? Will I have failed smog checks and should I get a smog check now to rule out the failed first engine? Catalytic converters are not cheap and I have already spent hundreds in tows and wasted time for what I thought was a good engine Jasper. So if Jasper reads this please respond with what responsibility Jasper has if my Catalytic converters are bad? Thanks Richard Lopez

One of the best companies for a brand new or rebuilt transmission. I was recommended by Rapid Transmission to this company. Would have cost way more if I was to bring it to another shop out in town. I saved so much time and effort with the convince of Jaspers service. The staff was amazingly helpful and friendly when calling them with my vehicle information, payments and their policies for transmission warranty. Could not ask for better service or affordable coverage.

PLEASE READ: About a year and a half ago I decided to not rebuild my 1990 Ford Bronco engine. I was told about Jasper Engines and that they have the right engine for me "0 miles, brand new, should drive just like it first came out from the lot back in 1990" well, its far from that. This is a truck I plan on having forever. I've already invested about $11,000 into my truck. About $5000.00 in the end just for the engine and labor. ENGINE #1- I got the first engine in 2019 April, a little over a year later, I notice the smell of coolant but never saw it. I went under my truck and saw so many coolant stains. I contacted the shop where I got it done, they ran a test and told me "you need a new engine, warranty covers it" even though warranty covered it, I still was out a few hundred dollars for a rental vehicle. Finally, get the engine up and running. ENGINE #2 - I have the new engine installed, about 2k miles later, I see a small puddle of coolant towards the middle, near the transmission/ rear-main seal.???? I go underneath to check while I'm at work and noticed coolant coming from the engine block AGAIN!! Going onto engine #3 in less than 2yrs!!! I'm currently trying to decide how to go about it. The process will start 01/11 on Monday. I work 16hrs a day, I dont have the time to be going from place to place, don't know how I'm going to get a rental and drop off my truck. Especially since the rental shop is closed on Sundays and work at 5am Monday. Now, is it bad engines or bad mechanics at the shop? The shop I get my work done say they've never dealt with an issue like this the many years they've been working with Jasper Engines.. Thank god I also didn't get a transmission. Jasper engine, please, please please, make the 3rd one work, you guys are causing me nothing but trouble and even though the warranty covers it, I still lose out on money cause I need a rental and I have to leave work early to be able to get a rental. Its so sad that I'm getting jse to having to take my truck to the shop over your engines. Over and over again!

So my utility van broke down while driving up the state of California headed to a job site.A service repair shop ordered the transmission from Jasper and I can tell you from experience and being a business owner with multiple vehicles that this transmission is not only the smoothest but also the most reliable backed with the best warranty I have seen. I would recommend these guys to anybody over the random mom and pop shop rebuilds. Their warranty says it all

If I would be able to give this business a 0 star I would. Our company M&M coach specialist has been doing business with Jasper for years. They have always paid us 110.00 HR labor rate. On the last job that we did they turned back around and paid us only 35/HR labor rate. I guess they must be on something good because no shop will ever survive on 35/HR. We learned our lesson and we advise anyone that is planning on doing business with Jasper to turn around and look for another supplier. We are a small business that depends on jobs like this and paying us that low of an amount is an insult Please do not do business with Jasper

So far so good in terms of both transmissions and engines; haven't had a customer claim a warranty as of yet; our small family owned shop (D&S Automotive) tries to look for the best prices/warranties for our customers and with a 3 year/100,000 mile nationwide warranty plus super convenient drop off and pickup schedules - Can't go wrong, give Jasper a call and see if the price/warranty is a good fit for your budget.

So far nothing has been right, on second motor now and still having problems. Mechanic keeps replacing parts that were good before motor was replaced, can't get oil pressure up so engine light keeps coming on, just replaced radiator to make sure oil cooler wasn't blocked.

Terrible promised id have my engine with in 4 weeks. 8 months later still nothing. They lied for 7 months saying it was a parts delay only to find out that they never started it even though i paid them in full when i placed my order.

What impressed me about Jasper is their pursuit to fix inherent flaws in a system, be it Engines or Transmissions.. As a performance engine builder myself I can respect and applaud Jasper Engines an Transmissions for their striving to go above an beyond to supply an promote Quality....👍🏻👍🏻
