JASPER Engines & Transmissions Reviews

I wish they 0 stars because all of their motors are scrap motors from the junkyard. Including transmissions. Their staff doesn't reply or answer calls. If you use this company plan on lawyer fees along with the expensive scrap they sell.

We purchased a motor from Jasper for a 2005 Ford Explorer. It lasted about 2 months and then we had to replace it. We reported it to Jasper. They told me what would be covered. My mechanic removed the bad motor and replaced it with a new one that Jasper sent. They sent the bad motor back. Jasper checked it out and reported back to me that the issue with the motor was not on their end. It was on ours. My mechanic explained to Jasper that the problem was due to the motor. They agreed to replace the motor but would not pay for the labor.

A Jasper remanufactured engine installed in 2022 leaked coolant through faulty head gaskets that blew right out the exhaust, untraceable. At no time did the engine overheat according to the gauges, the heat tab was on the engine, and the vehicle was only driven about 13,000 miles in the last three years. The mechanic said it was a faulty remanufacturing, but Jasper was defensive and unsympathetic. They said it doesn't matter how little the car was driven if it was past the warranty, but the remanufactured engine was faulty. Strange things happened after the company representative contacted the mechanic. Using the Jasper remanufactured engine cost us about $9000 in 2022, and it's gonna cost us about $10,000 to replace it. Parts just can't fail in under 13,000 miles, unless they were defective to begin with. I cannot recommend a Jasper remanufactured engine or transmission and will never use them again.

Bought a motor a while back from them. 18k miles later it shot a rod out of the block. 4 months passed. 3yr warranty. Best they can do is give me 8% discount on my 6400 dollar motor which is a whopping 440 bucks off. I feel they should have done better that. Might have better things to say about them if they could fix the issue and be more fair after just buying a 5k motor from them.

I live in the suburbs of Houston, Tx and had a local mechanics shop install a Jasper remanufactured engine in my classic 1998 Chevy Silverado with 397,000 miles on it. The new engine now has over 300 miles on it and runs perfectly. The only issue I have found so far is the paint is scraped off of the oil pan pretty badly leaving a sizable bare spot. I had to sand and paint the bare spot to prevent rust.

I recently purchased a replacement engine for my 2011 GMC Sierra (5.3L with DOD delete) from Jasper Motors out of Jasper, Indiana. I was thoroughly impressed by the speed of service—ordered on a Tuesday, delivered to my doorstep by Thursday. That’s exceptional. The engine itself has performed well so far, and the build quality appears solid. I appreciated the clarity of instructions and how smoothly the swap went on my end. However, I did run into frustration with the $2,050 core deposit refund process. I quickly returned my original engine (properly palletized) the following Thursday. A week later, I called to check on the refund and was told that the engine had already been inspected, certified free of cracks or holes, and approved for a full refund—on the same day it was received. But I was also informed that no refund had been issued because I hadn’t specifically called to request that it be sent.

The WORSE engine company, do NOT buy any of their products! In three years we went through three of their POS motors for my 2013 F150. This all started during COVID. Ford had a 8 month backlog for a factory motor-replacement and Jasper was the only one around when I called that had a motor. Day one it had a valve or crank tick from the moment I picked it up from the shop. They said it would probably go away during the break in periods. I kept that motor in hoping it would go away for about a year and maybe 12k miles, well the tick never did go away.

I'd leave ZERO STARS FOR THIS GARBAGE BUILD if I could... Wrong pushrods, Galley Plugs found in oil pan (QC check?), Not an easy access on a 96 F-150 to find. Short pushrods (QC check?) caused chewed up camshaft with less than 5k miles on it but a year over time limit on warranty. ALL issues from build and they don't care. I'm not a wealthy man and just wanted my father's truck to be able to be driven around, have some good memories of him but I'm $10k into an engine that still doesn't run right. WOULD NOT RECOMMEND THIS COMPANY TO MY WORST ENEMY!!!!

I purchased a Jasper Rebuilt Engine early 2024. The check engine light went on and the engine had to be replaced 7 months later, under warranty. The second Jasper engine failed 6 months later. After much negotiations Jasper sent a replacement engine no warranty as a year had passed since the first engine replacement. I signed a waiver that the engine would be no charge, but I would be responsible for labor to replace. They don’t warranty each engine for a year, but only give one year warranty from the time of the first replacement. The third engine misfires and two cylinders at 2500 RPM. Not one of the replacement engines went 25,000, let alone 100,000 miles per their warranty. I sent my report to the BBB. Based on the three rebuilt engines Jasper sent, all of which had significant problems, I would never recommend Jasper Engines.

I was recently looking for a transmission for my brother's truck Ford f-150 looking on Facebook Marketplace. I found tons of ads placed by different people but all were connected to Jasper auto sales. 90% of them were from another country and it was frustrating to deal with. I had to cancel my credit card due to a bad feeling of being scammed, been there before, not with them though. I just couldn’t trust the deal. I called more than one of them, maybe 10 different times, different people, prices changed over and over, never the same. I will never deal or recommend them to anyone. I know not trustworthy like I said, I had to cancel my credit card for a new one, Dammit.

Bought a Jasper Engine for my 2012 Jeep Grand Cherokee Limited back in 2021. Just before the warranty ran out, had to replace the engine. Had put on less than 20,000 miles on it. Really?! Got a new engine put in and now the engine is failing again and they say, even though it is a new engine, the warranty was only on the original engine, so this one is not covered. Are you kidding me!! You are not going to cover an engine that is not even a year old??? And we had to have 3 different transmissions put in for different reasons, including the one of the new. Ones had shavings in the transmission. What kind of company does not stand behind their $10,000 engine that is less than a year old!! Basically they are making it so my Jeep is no longer drivable and to put another $10,000 into it is a waste of time!!

What a crock of crap. Jasper Engines is not a company I would recommend to anyone after the experience I'm having with a warranty claim. I paid 3k for a 4.3l. It lasted 16k mile and blew a head gasket the day before I was to start a $6000 job that I had to cancel. Now they are telling me they won't renew the 3yr warranty I paid for on the first engine that failed. By all rights and logic they should renew the warranty on the replacement engine. Logic says that would be showing respect and commitment to customers. Sadly Jasper Engines does not respect their customers So If you're looking for a new engine DO NOT BUY A JASPER'S.

So I purchased the 68rfe with a triple disc torque converter, yesterday my vehicle had a problem and wouldn’t shift….. They offered me nothing basically, told to go pound sand. Go buy a fire punk 68rfe before you waste your money on their transmission assembly. I also pulled my transmission apart today and found the valve body was loose and not torqued properly. I found all bolts installed finger “snug”.

If I could leave a 0 star review, I would. I purchased a 6.4 hemi Jasper motor (June of '23) after the stock motor dropped a cylinder at 160k miles. The first motor made it less than 2k miles before it started burning 1 quart of oil every 500-700 miles. That motor was replaced under warranty, although it took almost a year of oil consumption documentation before Jasper agreed to replace it. The 2nd motor lasted less than 5000 miles before it started knocking in cylinder #8.

Had a Jasper transmission installed in my 18 Sierra. The first transmission went 30 miles, had my vehicle towed back to the repair shop. The second transmission was installed and in less than 500 miles it started to heat, shift at high RPM's and would not shift into 6th gear. Rebuilding with cheap Chinese parts?

Very Poor Quality Engines and Warranty. Just had a Customer whom I recommended Jasper for their Quality. Also Customer Paid for Additional Warranty Coverage. New Engine was NO Good, Rattling on Start-Up. Got Jasper to send another engine and it had the exact same problem. Tried to get Problem Solved with Jasper, Only Now they say Customer drove first Engine in to water Ruining it. Which was a lie, Engine was never in water and Ran normally after the start-up rattle went away. Again, 2nd Engine does the EXCACT Same thing, from 1st start. Jasper Refuses to take care of customer or the shop they under paid. Stay Away from Jasper Engines and Transmissions.

Jasper engine for my 1990 Toyota 4- runner. Had for 4 months and head gasket leaked. They fixed it right away. Now 7,000 miles later 3 valves on the left all failed, and Jasper has not honored their 3 year/100,000 mile warranty. I keep my car meticulous and have every record since the day I bought the car. This is my third rebuild engine (576,000 miles) so not a newbie to the rebuilt engine idea. My last two engines lasted much longer than 3 years and 100,00. If Jasper does not honor the warranty - it has been 1 month, I will take legal action against them and file a formal complaint with the state.

Jasper used to be good. Not anymore. Their quality of products and customer service has dropped to a new low. We put in two Jasper motors this past summer 2024 and both are leaking all over. We reached out to the warranty department and told them that there was a leak between timing cover and block. He didn't believe us and told us that it was probably coming from not properly installed valve covers, which he said was a known problem area that needed to be redone before they would pay for any repairs because he said it was our fault. So we redid that repair knowing that that was not the problem to appease Jasper. What do you know, but it was still leaking in the same spot.

I don't usually write reviews but I really feel that future consumers should beware of this company. In November of 2023 we had the original transmission replaced with a Jasper transmission. That transmission failed after only 3 1/2 months. Jasper replaced that transmission but we were out of the labor cost, replacement of the cost of the other engine parts that were damaged because of the failure and missed work. Only to have that transmission fail in August.

Worst garbage engine I have ever bought. Jasper worst customer service. They do not give a rat's butt about you or the quality of their rebuilds. First time and last time I will ever use Jasper. 100 miles clicking, ticking upper end piston rod bearing making noise. Try to get Jasper to help. Ha ha ha. Good luck.

I overpaid to get a Jasper transmission for the warranty to find out they only pay so much. I put 200mi on when I started having issues. It's been in the shop 5 times for the same problem. I went to the shop they sent me to and ended up paying 500 out of pocket because they only pay so much labor. Then why send me there if they knew it wasn't going to be covered

I bought a Jasper Motor and it imploded, after an expensive tow job and an expensive diagnosis and paying $100 a day rental about $3,000 they sent a new motor. Then 3 months it fails. After an expensive tow and diagnostic tests and $100 a day rental they sent another motor. After 6 months the motor failed. After an expensive tow, and expensive diagnostic a new motor was sent. Keep in mind Jasper doesn't cover towing, it doesn't cover the mechanic checking multiple parts, it requires many new parts for the warranty to be covered. It doesn't cover rental. If I had advanced knowledge I would have bought a $30,000 truck rather than suffer their crap. And Jasper used to be a credible company.

I needed an engine last year for my Trailblazer 5.3. I got the DOD delete and had it installed. I was very satisfied with the engine. It had more power than my old engine and ran better than new. This year, the engine failed. The installer checked it and it seems that the timing chain failed with 11,000 miles. They contacted Jasper and Jasper did right by me. They didn't try to patch it. They warranted the engine and the Installer had a new Engine in like 5 days. The engine is in and I am rolling again. I was inconvenienced but being an old gear head, I am aware that any part, even a brand new part can fail.

BUYER BEWARE‼ Two of the last three motors have had significant issues. Takes weeks for core pick up and even longer to get paid for the warranty labor. One of the last three motors we got didn't even have the rocker arms torqued down. On an engine that was ran for 50 hours?! I think not.... That was super fun after getting the job done and don't forget you have to wait 8-12 weeks and cross your fingers the next guy decided to do via job when he was working on it. Customer service is nonexistent. Good luck!!

Would give ZERO stars if possible. Completely disappointed in customer service and quality of their products. For anyone wondering if they should give this company a chance, DON'T. A 1.4 star rating is being GENEROUS considering they do not even warranty their products as stated.

The second transmission that was already installed in our 2015 GMC Yukon XL Denali when we purchased it in March of 2023. That transmission failed before 30k miles. We just had another Jasper trans installed last week, which it is already failing with less than 200 miles on it. It slips between gears, going uphill it sounds like it is eating itself, and it drinks fuel now. You can actually watch the gas gauge move toward E. We had to pay the shop $1,866 of which Jasper is only going to refund $800. The vehicle is how we get back and forth to work, it is our only vehicle. And time is money. We are going to have to be without the vehicle again, only to be given another giant paperweight from Jasper and lose even more money and time. Jasper should really think about going into a line of work that doesn't involve engines, mechanisms, or transmissions.

Do not buy from these guys. 2 transmission in less than 150 miles. Second transmission did not work. Carried to transmission shop and gave Jasper the number to the shop. Jasper did contact shop. Diagnosed as bad torque converter. Shop replaced. I paid repair bill and called Jasper about repair bill and they denied.

Purchased a Jasper in lieu of a new or used one for my wife's Lincoln Navigator. It didn't make it even a 100miles before failing. They WILL NOT give a full warranty, costing $1000+ more to get the replacement installed. There's just no value here. You're better sourcing one on eBay or such for real savings as you're rolling the dice with Jasper also.

In July 2021, my Duramax, 6.6 L diesel broke its crankshaft. I had to replace the engine with a Jasper short block. In February 2024 the engine dropped a valve into the cylinder. Jasper warrants their diesel engines for two years, unlimited mileage. This happened just over two years. The engine only had a little over 12,000 miles on it. Jasper would not even help a little to repair the $24,000 engine. Now my 2008 GMC 2500 HD truck is DOA and I have no recourse but to take the truck to the boneyard. I will never purchase another Jasper engine again.

Purchased a Jasper Transmission. After about 4 weeks of use I totally lost reverse. I purchased a 3 year/100,000 miles warranty. (Parts and Labor). I was told that Jasper only covers up to 90 dollars a hour on labor and doesn’t cover fluids. So now after purchasing a s 6500 transmission and paying to have it installed. I will now have to pay an additional 45.00 dollars a hour per hour of repair and an additional 190.00 worth of fluids. At my own expense because if the transmission failure that is a 100 percent defect from Jasper.. Buyer Beware…. I’d give zero stars if possible.
