Customer ReviewsforJasper Engines & Transmissions

I have been through two motors in less than 3 years. these motors are junk period. The second motor I told them I want a full refund which they quickly agreed to but nothing for my time. I will never get another remand engine ever. I will junk the vehicle first. wish i could give them negative stars cause it would be negative 10 for sure.

pure junk 2 engines in my truck and both failed in less than 2 thousand miles

Great product! My 2003 highlander has 320000 on their engine.

We had the original transmission replaced in our 2015 Ram 3500 in November 2023 with a Jasper transmission after a catastrophic failure, only to have the new Jasper transmission fail just 3 1/2 months later in March 2024. Jasper covered the cost for a new transmission but not the cost of the labor, damage done to other engine parts or the time off work (we use our truck for our hotshot business). So after being out of $9,620.00, not including missed work, the transmission failed again in August 2024. We chose a transmission specialist to look at it. There was metal chards in the pan, a loose bolt and a broken rod. It cost us $7000 to have the transmission rebuilt. Jasper says that because we didn't do a warranty replacement with them AGAIN that there is nothing to be done. Why would I have another Jasper transmission installed after 2 failures. They didn't fully cover the expenses of the last one as promised and we cannot afford to keep doing this. Their product has cost us 10's of thousands of dollars and they could care less. Horrible product and customer service.

Spent over $4500 on engine plus new parts from Quality Automotive biggest stupidest mistake of my life. The motor had no power made a lot of ticking noise took back every 3 months Jasper and Quality Automotive did nothing to make it right so don't be fooled by Jasper having good rebuilds stay as far away as possible look for 5-7 year no fault warranties from good reliable honest rebuilders and find a good honest shop to do the works. I called Jasper directly with the receipt they do not give a crap about there quality there customers. I pleaded with them is there anything you can do to help me out I need a new motor the customer service rep practically laughed. JASPER IS NOT A GOOD RELIABLE REBUILDER, don't be fooled like I was.

Wouldnt put one of there motors in anything.....3 years 72,000 miles on the third p.o.s jasper motor....

Purchased a replacement 5.7l HEMI Engine for my 2013 Ram 1500 at 101,000 miles. At 128,000 miles or 27,000 Miles on replacement engine, I noticed extreme oil consumption. Took back to my mechanic and he varified the extreme oil usage. They contacted Jasper and wanted a new replacement engine. After some hagling, Jasper said they were having some issues with the valve seals on that particular model engine. They sent my mechanic the improved valve seals and reimbursed them the installation cost. Although, not at the hourly rate they normally charge. So I was without my truck for about two weeks. I now have 61,000 on the remanufactured engine and it is doing fine so far. It is warranted for 100,000 miles or 3 years. So i'm statisfied that they stood behind their product. My mechanic is still kinda of upset that they did not just replace the engine or pay their mormal rate, but all in all in worked out in the end.

Very very angry, our remanufactured engine from these people threw a rod at 33,000 miles, 4 1/2 years later so they won’t touch it! I wouldn’t want another one of their crap engines again anyway! That engine should have lasted a lot longer than that...we are now out $6000 for engine and labor!!! They are not putting out quality workmanship ... I will tell my mechanic he should never buy from them again! I wish we had checked them out before he bought from them! ??????????

1 STAR is to many! Like many others I purchased a replacement transmission from Jasper and the warranty. Well less than 1200 miles later, most of the miles getting home from two different dealerships. Transmission is shot. Only to find out that yes even with the additional coverage that I purchased on the labor I will still be paying about $60 an hour out of my pocket for the replacement of the new transmission because the original one sent was crap. Typical, they do anything they can to avoid covering their sub par workmanship. Spend the extra money and purchase from a company that stands behind their product. Jasper is not that company! DO NOT BUY from JASPER. Crappy product and even worse customer service. Run as fast as you can if the shop recommends a Jasper product!

We have been dealing with Jasper since August of 2022. We ordered an engine core for our truck, received it, installed it and it lasted 29 miles. The truck was towed to our GMC dealer to confirm it had blown a rod. We contacted Jasper and they sent another engine core out and the defective one was shipped back to them. The dealer installed the engine core. This one lasted 989 miles. At this point we have lost all faith in Jasper Engines. In talking to customer service they will not refund us our money unless we pull the defective engine out and ship it back to them and they will send us yet another engine core we don’t want, plus we would have to pay labor costs to pull the defective engine. They are asking too much of the customer and not being held accountable for their inferior products. It’s time for the DOJ to step in, especially after reading complaints one right after the other with the same exact issue. We are an elderly couple on a limited income and this has been a financial burden. We will be filing a complaint with the DOJ. This needs to stop. I believe any of the 5-Star ratings on here are written by people who work at Jasper trying to bring their rating up. Terrible company! Don’t buy anything from them.
