Jasper Engines and Transmissions

This is by far the bottom of the barrel as far as engine rebuilders go! I own a Marine Service business and recently installed a Jasper 4.3 Litre Chevy Marine engine. It failed within a month! They did replace the engine after much headache. The second engine failed right at about a month after install as well. This time I told the Jasper rep that some cylinders were showing water intrusion so I was pulling the cylinder head! (They did not like this). After the head was pulled there was a 3 inch crack in the cylinder wall. Bottom line:: They said it was detonation (idiots). I was never paid a dime labor on either engine failure, Guess what, The boat is back again. Jasper engines are garbage, warranty is garbage, company is garbage!!!

Installed 3 rebuilt Jasper motors on my 2008 Subaru Outback through Jasper in the last year and a half. They said they would refund the money if they got the engine back. That would render the car useless. $4200.00 just for motor, reduced rate for labor, multiple failures, quality of product very disappointing. They said they would give us a $250.00 credit. Oh Wow then what? Take the bus with my tools... Can't even give it one star.

I replaced all the injectors on my 6.0 Super Duty with Jasper injectors. Less than 6 months one goes out. I was told when I replaced them I received a 2 year parts and labor warranty. I take my truck to the shop and was told I had a bad injector. I showed them the warranty and he said ok. They started repairs on my truck. They had to jump through many hoops to get the part then I was told Jasper will only cover $75.00 of the labor. WHAT? Where can you get a injector replaced for $75.00? Nowhere! I called Jasper and got nowhere with them. This warranty isn't worth the paper it's written on. I'll never buy anything from them as long as I live. Jasper can kiss my **!

Back in 2012, I had a 5.7 liter Jasper Engine installed in my 96 Impala SS. At the time the car had 269,000 miles. It now has 303,000 miles. The Jasper engine didn't even make it to 35,000 miles. Today it apparently blew a head gasket. It dumped a huge puddle of oil and coolant in the hospital parking lot. Today, I had it flat-bedded home. Called the Jasper tech and told him what happened. I said, "you sold me an engine that couldn't make it to 35,000 miles." He pointed out that it was installed back in November of 2012. So I am just out of luck. I asked if Jasper would step up with an extended or hidden warranty. The answer was short and to the point - "nope". Needless to say, I don't recommend buying an engine from Jasper. 35,000 miles after only 5.5 years and the engine failed. Garbage!

Very disappointed with my purchase of a 5.9 Cummins. Had fuel issues from the start. They blamed everything on fuel issues. The problem was injector pump. Sloppy rebuild pump was sucking air thru. The front shop who install engine had no clue lead me along till warranty was up. Took it to another diesel specialist who said it was a common problem with Jasper rebuilds. Would not recommend them to anyone.

Being familiar with the Jasper, IN area and some people who work at the Jasper engine and transmission factory, it was a no-brainer that I'd turn to them when a problem appeared in my daughter's 2006 Chevy Trailblazer 4.2L engine. With the first replacement, the engine was subject to dying at inopportune times, even after they said it would stop! Engine number two, about five weeks after the second oil change, I discovered the engine was about two qts low on oil. Took it to a different Jasper provider in town and explained the situation to them and after the normal initial inspection, was told there was compression loss in three of the cylinders.

1997 Chevy Silverado - My transmission failed on me while I was out of town about 5 years ago. I knew I wanted to keep my truck so I bought a JASPER. I like how they research the common issues and fix them to make it better than the original. My transmission had a long list of updates! Once I found out they are 100% employee owned and their factory is in the US... I was sold!

Engine (Cummins 5.9 diesel engine) bought Sep.2018. Installed in Las Vegas, NV. Cylinder head cracked, noticed in Yuma, AZ. Went back to LV, to replace. Found no. 1 piston installed backwards at Jasper the reason engine vibrated. Jasper paid for partial labor, & parts. Diesel Specialties replaced cyl head, & fixed piston, at no charge to me, except for 1,100.00 expenses for 2 trips Yuma to LV, motels, 4 nights car rental. Jasper made the mistake. They should make an adjustment for a refund for expenses. They said NO. Same with Diesel Specialties. Very dissatisfied.

When I take my truck to get oil change at my TRANSMISSION shop they discover a crack in my Jasper transfer case. Called Jasper, confirmed warranty is still good. Customer service confirms still under warranty, no problem. Following day, a different customer service rep calls and said I need $800 so that we can cover shipping and investigation. I burst out into laughter. I explained to the representative that from the back of the transfer case to the rear differential is perfect, from the front of the transfer case all the way to the front bumper of the truck is perfect but the transfer case in between has a crack in it. No investigation needed. Please stand behind your warranty.

Had a Jasper 5.9 Cummins diesel engine installed replacing OEM with 180,000 plus miles on it. 13 months later injector goes out. Call Jasper, they blamed me for using bad fuel. Also sorry warranty over for injectors at 12 months. Replaced injector and find out it was not properly torched to spec at 37 lbs. It was basically had tight (no quality control). 25 months rear freeze plug starts leaking. Call Jasper, "Sorry warranty up at 24 months". There is no end user customer service. They only protect their shops that use their product. Do not install a Jasper motor in your vehicle, they suck.

Like any company you don't know how good or bad they are until you have a problem. I am an ASE tech and an ACDelco master tech for 30 years now. I installed a 2005 Ford Escape engine from Jasper. On start up the lifter was making noise. I called Jasper immediately. I was told that the lifter noise was normal. What? I was told to drive for 100 miles it will go away. Then I had to explain to my customer that the new motor makes noise and it's normal? Plus pay me in full for a new motor with engine noise. That's a hard sell. But I did. Long time customer of mine so he understood. He drove it for 200 miles plus with still a lifter noise. He also called Jasper and they told him the same story. Lifter noise is normal for this engine. He was very patient but wanted the job fixed. Understandably. He paid a lot of money to fix his 2005 Escape.

Spent over $23,000 on new Jasper 6.0 diesel. Had it three weeks and left for Denver. The new engine blew and of course Jasper won't pay anything until they get the old block back! REALLY??? I'm stranded because of a new blown warrantied engine and now out motels and rental cars plus I have to pay labor out of my pocket and wait to get $70 per hour reimbursement. Of course nobody charges $70 per hour anymore so I'll be out money on a 3 week old engine. Even after spending $23,000 to begin with. Where is customer satisfaction these days??? Even tow bills for truck and 5th wheel. Come on!!

DO NOT "TRUST" that their, JASPER, "Installers" such as Lakewood Auto Inc are competent. Jasper lists business on their site and This "Jasper Installer" wrecked my vehicle, was driving my vehicle, had my vehicle for 17 months (though they were paid) took my car to a "d" BBB rated shop (found my car on the side of road) then refused to give car back! REALLY BAD HOSES on ENGINE, Cracked leaking hoses, parts invoiced "DO NOT FIT YOUR VEHICLE" - CHANGED PARTS I had just replaced without permission - QUOTED two different prices (one higher than the other by 1200.00) then charged 1000.00 Higher than the "higher quote". Car towed and towed and towed after Jasper Engine installed.

4 months ago OEM went out so I put a Jasper in instead of a used only 1000 difference. So at 3 months and 3000 miles take it in and they find a oil leak. So I cant take it back to original installer cause the engine went while on the road, over 300 miles away. So take to a local dealer who does Jasper engines. Plus a month more driving cause my other car went down. So I get that fixed and take this one in. 2 weeks later I call about mine. Mech got sick. Why it is taking so long but that is not my complaint

Bought a 6.4 Diesel engine from Jasper. Didn't even get 20000 miles out of it. The Jasper installer told me it had a 2 year warranty. 13 months after having it the crank goes out in it. Call on warranty. They said it was out a month ago. They do not stand by their warranty. They rob people of their money. Mine was 14320$. My advice is to never buy from them.

I purchased a Jasper engine at 157323, because my stock engine failed. The Jasper engine failed at 196232 miles and 41 months of service. Jasper pointed out that my warranty expired at 36 months and now the engine is "too old " to cover. I was also told that "41 months of service is an acceptable amount of life for a jasper re manufactured engine". I babied this motor, not allowing rpm's above 2500. Turns out something fell apart in the engine causing the #2 & #5 cylinders to have 25% compression. At this point it's cheaper to buy a new engine for me. Something caused the pistons to contact the valves.

I purchased a completely rebuilt Chevy 6.0 liter engine installed by a local garage. The engine runs perfectly. It's the first motor I've ever owned that idles perfectly without the expected miss now and again. Freeway mileage with my 2011 Silverado 2500 Crew Cab is 20+ mpg.

The block on the original 5.7L engine on my '93 Suburban cracked at around 225,000 miles; water in the oil = ruined engine. I arranged for a Jasper Engine from my local mechanic. That engine also had a crack in the block that was "repaired" with steel epoxy. It failed after only a hundred miles or so. Jasper completely covered the engine, and sent another engine within a week. I now have about 60,000 miles on that engine and it's running very well, doesn't use oil, doesn't leak, has plenty of compression, and I would trust it to drive across the USA.

I purchase a turbo for my F-350. My claim were not paid because of the turbo. The metal on the turbo came apart and ruin my engine. The engine only had 100,000 low miles for a diesel. The metal shaving from the turbo caused the problem. Scarring parts inside the engine. Now I have to replace my engine. Even though the turbo ruin my engine. I called Jasper. It didn't do any good. Please don’t purchase any parts from them unless you want to purchase a new engine. Turbo are garbage. DO NOT PUT YOURSELF THRU IT.

I bought a Jasper transmission through my local mechanic, who raved about them. It was significantly more expensive than my other options, but I was sold. The transmission failed, and since I was FIFTY MILES over the mandatory trans fluid replacement interval, they said no.

Jasper Engines & Transmissions are awful, awful engine rebuilders. DT466 Reman lasted 18 months before injector cup blew out, head needed to be pulled. 3 years in rear main started to leak. 4.5 years completely imploded. Asked for a discount on a new Reman. Would not give a nickel. Awful company, never again.

This is a rebuttal to Southern Cranes review and issues with a Jasper Engines unit. I am the shop that had to replace the Jasper unit you installed. The vehicle was towed to us from your customer with the engine running rough and smoking. Diagnosis found that there was a hole melted in one of the pistons. Tear down inspection of the engine found extreme heat evidenced by discolored exhaust piping and discolored turbo inlets from very high temps. Further diagnosis found that the truck had an aftermarket performance programmer installed on it at time of sale from you to your customer. Any search online of the Ford 6.4L diesel engine will show that engine is notorious for cracking or melting pistons when aggressive performance programmers are installed.

I own a 2006 Mazda MPV Mini Van which I purchased new. The trouble started when the MPV hit 110,000 miles, the engine died! I was sitting still in a construction zone and the MPV just quit, would not start back up. So off it goes to the Mazda dealer (Knoxville, TN). This dealership sucks, but it is the closest to where I live :( I have learned to dislike them as much as the junky jasper engine, that they put in my MPV at a cost of $6100.00! First the Mazda dealer told me they were putting in a "New" engine. Well its not new, it's refurbished!!! I had the choice of a "refurbished" for $3800, but I said no, that I would go with the "new" one, at $6100 hoping it would last a few years?

I purchased a 1976 Ford Bronco in July with under 3000 miles on a Jasper motor. Within 400 miles, the motor failed. I was advised to take 'Pearl' to a Jasper dealer which I did. Over a period of months, the motor was sent back to Indiana to be rebuilt, parts failed during testing there, delivery delays. Jasper refused to pay labor costs indicating that I was somehow to blame. It's my new company truck, I need it on the road, so I paid labor, $1800 and change. All the while thinking I'd have a NEW Jasper motor with another warranty. That's what Jasper is in the business of doing, right? WRONG.

Jasper Engine: I purchased a Jasper Engine for one of my customers and the engine was installed and ran for 6 months -- the engine locked up and Jasper says they have a 1 year parts and labor warranty -- they covered neither my customer is faced with installing another engine at his cost. They did nothing -- so now either he will have to take Jasper to court -- the problem is the time and money it takes to do that in the meantime his work vehicle is down and it is a $80,000 dollar vehicle -- that would cause hardship on him. Jasper Engines will not cover anything and it is the engine itself that broke or has a hole in it.

I have been doing business with Jasper Engines and Transmissions for over 20 years. Jasper supplies the highest quality products. I HIGHLY recommend them.

Excellent company to work with. Always very friendly and knowledgeable. Would highly recommend their products and services.

In July of 2014 I was on my way to Mount Rushmore in my 2002 Jeep Grand Cherokee when the cooling fan went out in Sparks, Nevada and ruined the engine. I took the car to Wayne's Automotive (who are super to do business with). They said the engine was shot and recommended a Jasper engine as a replacement. With all the parts and labor the cost was over 9000 dollars. The follow August a very loud racket started under the hood. I called Wayne's and they said no problem bring it in and they would fix it because it had a 100000 mile 36 month on the engine. They replaced the engine for no charge. I drove the car with the second new engine about 5000 and again the engine failed in Las Vegas.

I am looking for an engine for my 96 Chevy truck and when I read all reviews about Jasper Engines I see a big red flag. My best thought is to turn, run far and fast and hope the rest of us who are in the market for auto parts read the reviews first. You will save a ton of money. Less gray hair.

I bought a 2001 Chevy 3500 Express Cutaway in 2014 with supposedly 40,000 (original) miles. At 56,000 miles the transmission went out. The mechanic was under the impression it had a great warranty on it, and after checking, discovered it was a 3 year/100,000 mile warranty. In checking with Jasper, I found out that the transmission had been replaced in 2012, which meant that the transmission had to of gone out in less than 30,000 miles both times. I will never own a Jasper transmission, nor buy another vehicle with one in it. If a transmission can't last 100,000 miles, it is total junk and is faulty in all aspects of the word. Obviously they will not replace it in any way shape or form.
