I purchased a Jasper transmission for my “custom” jeep (as they put it) in I believe August 2019. It last less than 2000 miles. I took the vehicle back to the “authorized dealer” and it was replaced. I was told a gear burned up. That should have been my first clue The second transmission was out in and at the time I asked the shop manager if a trans cooker should be installed and he told me no. Second mistake. That transmission did not last very long either. That was replaced with Jasper transmission #3 in July of 2021 with a trans cooler. It lasted until last month and gave out. I contact the shop that installed the transmission and the same shop manager said he would contact the Jasper sales rep and see what could be done. I will add that I took my jeep to the shop that I had been doing business with for several years.

The next day my jeep was dropped at my residence with no word on what the problem was and when I called the shop I was told by the shop manager that his father had looked at the transmission and would call me back. I never got a call that day so I called back the next day and the shop manager became annoyed and raised his voice Dayi g his father would call back. Once again no call. After 2 weeks of no answer I contacted Jasper via email and received a call from the sales rep who told me that the transmission was out of warranty and that there was not a problem with the transmission but it was a problem with the valve throttle cable not being adjusted properly.

I called the sales rep the next day and asked for the declination in writing but he just referred me to their website where the warranty was located. I then asked him to confirm it was the throttle cable that caused the failure and he changed his story stating that it was mere “speculation” on his part based off the failure of the previous two transmissions. At this point I file a report with the BBB on Jasper and their reply denied any blame on their company but blamed the authorized dealer for the improperly adjusted throttle cable and they have refused to make any amends on their transmission. But rest assured I will never buy another product from Jasper. Their attitude towards their customers is that they could care less.

I purchased an engine block for a 7.4 liter engine in my boat. I paid top dollar for this engine. My boat was now running for about 6 miles out in to Lake Erie. That was when my Jasper engine blew. That was on May 10th. I finally got my warranty engine on July 28th. They lied about not being contacted until July 3rd. This was peculiar because they sent a person in late May to do a check to see if I got the engine hot, so they could void my warranty I'm sure. I warn anyone not to buy anything from this company. Pitiful service to say the least.

    My original Chevy Silverado transmission was replaced 3 times in under $100,000 miles total, with a Jasper Transmission and should've been replaced again. The 1st replacement lasted approx. 36,000 miles. The 2nd replacement had a fluid leak and was replaced without question. The 3rd replacement had approximately 40,000 miles on it and had a bad throw out clutch to the torque converter and was replaced...again. The 4th and latest Jasper Transmission developed a whine, hence a bad torque converter, with only 9,000 miles on it. Jasper refused to replace this one, because it went above and beyond the warranty. I make sure I tell all my customers and mechanic friends to NEVER get a Jasper Transmission!! I'm not a mechanical expert, but I own a business and know cheap parts when used. I would've selected 0 stars given the opportunity.

    Hotshot hauling (based in Baltimore Md) with 2010 Dodge Ram 3500 Dually pulling no more than 10k at any time. My OEM transmission failed at just under 186k miles. 1/7/2021 I replaced it with the 1st Jasper transmission and it lasted about 3 months failure to a broken input shaft and left me on the side of the road in VA. It Stayed in the shop approximately one month. Second transmission failed about 5-month failure value body left on side of the highway in NC. Stayed in the shop for a little over a month. 3rd transmission broken at about 6 months failure to fifth gear, left me on the side of the highway in North Carolina, again Truck stayed in the shop for about 1 month. 4th transmission failure at about 6 months left me on the side of the road iN SC. Failure to the overdrive. Stayed in the shop almost 3 months.

    I was told there were no transmissions available at that time and was waiting. NOW at 256k, we are on the 5th transmission. I retrieve the truck from the shop and within the first week the transmission is showing signs of failure, not even towing just daily, driving, extremely hard downshift and throwing the check engine light with codes P.O. 845 reverse gear ratio, P.O. 746 transmission over temperature. No, the transmission has not filled yet, but I’m sure it’s on its way. Jasper's customer service is friendly and helpful but their product is TOTAL TRASH. I'm being told I'm running it too hard and or towing too heavy.

    We put in a Jasper transmission in our Suburban. Within 5000 miles the torque convertor went bad and they replaced it with another transmission under the warranty. That torque convertor went bad within 3000 miles and they replaced it again. We just recently got the Suburban back from the 3rd transmission being replaced and it has been less than 1000 miles and 3 weeks and the torque convertor is bad again. We will be putting in a fourth transmission within a year. It is ridiculous and we are going to be discussing other options at this point. I would never recommend Jasper to anyone. This is the worst experience we have ever had with any automotive parts.

    Had a brand new rebuilt transmission from Jasper installed on a 2006 Ram 2500. The transmission only lasted 3000 miles. They do replace the transmission but they do not cover any parts and they say how long it will take to take out and put in in the end after spending $7,000 on a new one. It end up costing me another $2,000 to replace one with 3,000 miles on it. The manufacturer themselves could not care less that is their warranty. You end up getting screwed in the end stay away from their transmissions and their company. I am in line with all the other terrible reviews about this company.

    Stay away from Jasper. Especially the transmissions. I guess they can't find good help or have any quality control. I bought a rebuilt E40D for my F350 and the torque converter failed after 5000 miles. They did replace it and the second one has almost 20,000 but I'm having trouble with it now and it's out of warranty. You're basically screwed if you spend your hard earned money on any of their products.

    Paid some good $$$ for Jasper to build me a lightly modified old school 350 to go in my 75 Camaro. Engine was rated at 350hp and lasted under 1200 miles before a flat spot formed on cam. They only gave me a 12 month warranty, and of course this happened at 14 months. I called them and they refused to stand behind the engine. Never again Jasper. Find someone else to buy from if you want an engine... Jasper is sub-par at best.

    Had a Jasper replacement engine in a 2012 Chevrolet Suburban and it failed just outside of the warranty time frame, but not even close to the mileage limit. Jasper did not warranty, but instead offered a discounted replacement engine at a reduced price, but with no warranty. The 2nd Jasper engine failed in under $15k miles. They refused to help on the replacement or with any parts. Terrible product. I highly recommend that you find another solution. We purchased through them because of their reputation, but as I've dug deeper I've found that their product and customer service have taken a sharp nose dive. DO NOT BUY A JASPER ENGINE.

    This company sucks. First they tell you a story that they have your parts in stock until they charge you and then they call you to let you know that your parts are not available and that your parts are going to be deliver in weeks while you sold the job and gave the customer a timeframe... Very embarrassing for shops due to negligence of Jasper. The worst part is you have to wait 3-7 business days to get your money back. Very bad business.
