As an auto repair technician and business owner, I have learned that quality parts are always in my company's best interest. Sometimes this lesson has been both painful and expensive. JASPER engines and transmissions are the only components I offer to my customers. The commitment to excellence and perfection of the final product is without question. This gives me great confidence when selling the JASPER product line to my clients, friends and family. Also, I chose to install a JASPER engine and transmission in my personal vehicle over all other manufacturers. I neither asked for, nor received any discounts, but instead based my decision on quality of product and warranty of product. In my personal opinion, JASPER is the only way to go for quality drivetrain components. - Ricky E.

Your facilities show tremendous high quality in workmanship. I was impressed with the number of people with ASE certifications. Also your compassion and support to your employees has given me a better outlook on my employees. - Walter K.

This impressive tour really shows me JASPER’s old-fashioned values of quality work, positive work environment and treating customers #1 really is the bedrock foundation of a successful business. - Roger L.

Just wanted to drop you a quick note of thanks. My staff and I thoroughly enjoyed the tours of your facilities last week. I believe that the trip will help facilitate a shift in our "engine mentality." Engine replacement has been a service that we have avoided in the past. The confidence that my service advisors now have in your product will make their sale tasks easier and also more frequent. - Lynn A.

Hello, I had a JASPER engine put in my son’s Wagoneer (AMC Jeep 360) and I think the feeling of dependability of a new engine is super. Knowing my son’s Jeep is reliable. - Stephen L.

I am writing to let you know how happy we have been since we started using JASPER at the beginning of year. We have installed a number of your engines and transmissions and have found your product to be of the highest quality available to us as an independent auto repair shop in the Houston Metro area. - Scooter O.

Just wanted to drop a note letting you know how much of an enjoyment it to do business with a company such as yours. Everyone from your inside sales to your area sales rep, Troy Pourciau are very knowledgeable and professional every time we come in contact. Thanks again for the unmatched service and keep up the GREAT Work !! - T.J. K.

Nothing wrong with Japser re-mans. One of the more highly regarded re-man outfits. It's also always a good pick as they are pretty much used everywhere and are real good with their warranties. As others have mentioned, if you have a good local machine shop and have the time to keep the car down, getting your old engine rebuilt can be a more cost-effective way to go and allow you to have some "fun" while it's out. On that note, if you have a Fiero, shouldn't you be doing an engine swap anyway? I've seen them with everything from a Cadillac North Star V8 to the ubiquitous supercharged 3800 V6. If you want to have some fun with it, the s/c'd 3800 is a great engine to add some fun and is dirt cheap to boot. - NJgoat (Review found on City-Data)

I've installed Jasper GM 305's and 350's before for a buddy and he was very satisfied with them. I have another buddy that bought a Ford 302 that is still sitting on an engine stand in his garage. For me I rebuild my original because of the matching numbers issues along with originality. That isn't a concern usually in a modern run of the mill vehicle though and the Jasper makes more sense. - 2ruggedforyou (Review found on City-Data)

I recently completed a tour of your facility in Jasper and just wanted you to know how impressed I was with your operation and more importantly your team. I want to thank you for spending time with me and answering all of my questions. I have been studying the principles of continuous improvement and was amazed by some of your results. Some of the improvements that you have made have given me ideas for my own operation. I would very much enjoy seeing your facility in a few years to see how it has progressed. I realize that the changes you are implementing are the direct result of the input from your people. I know that any organization is only as good as its folks and judging by the high caliber people I met, I can clearly understand why Jasper Engines & Transmissions is a first class operation! - Jeffrey W.

For those who keep cars and re-power them Jasper is the only way to go for a job without grief. As a retired diesel engine engineer I think so highly of Jasper's remanufacturing process that I plan to re-power my '93 Suburban, when the time comes, with a Jasper engine & transmission. - Grandpa (review found on City-Data)

I want to express my appreciation to you and all the Jasper associates who participated in giving their time in making last Friday's tour of your facilities a success for me. The entire operation at both locations is first class in all respects. As a new employee of Douglas Automotive and to the auto repair business, I can see how little I really know about today's automotive industry. Having assembled (a very loose term) a few small block Chevy engines for personal projects almost 30 years ago, I thought I knew something of the process---an incorrect assumption on my part! Having seen how the drivetrain components are remanufactured, in some instances better than O.E.M.'s did originally, has provided a tremendous appreciation of the quality behind the Jasper name. The associates I spoke with share your enthusiasm of total customer focus---I came away knowing the sense of pride each person showed in doing their respective job! Thank you again for the hospitality and courtesy extended to our group during the visit and I look forward to a continued, profitable business partnership between Jasper Engines and Douglas Automotive. - Pat M.

My father had a Jasper engine installed in his station car a couple of years ago, when the original engine blew somewhere around 200k miles. There were no problems with the Jasper engine, and the mechanic who installed it has a great reputation, so he would not use junk. The engine was still going strong when the car was totaled, while parked, during a mild snowstorm. The replacement engine survived, though, and was transferred to a car that was being fixed for a low income family, so it's probably still going strong somewhere. - BMWguy (Review found on City-Data)

We wanted to thank you for letting us participate in such a wonderful tour of your factories. The plane flight, food, facilities, and people were all enjoyed. You have definitely completed your goal of showing us your remanufacturing procedures firsthand. For a company to spend the money and effort on showing us "how you do it", anyone can see that you are doing your absolute best to produce the perfect product. Seeing the factories has definitely given us the extra confidence to help make a Jasper product sale. Thank you again. As long as you are holding your standards this high, we will continue to make your product our first option for customers. - Brad H.

My friend is a mechanic and highly recommends them. - John F (5 star review found on City-Data

In 40 years of being a mechanic, fleet manager, and District Manager for Heritage Propane I have never had a good experience with a rebuilder until now. WOW, what a team! I envy you having so many competent people working for you. After this experience you have all of my business. - R.W. K.

I was amazed by the technology involved in the plants. A star note goes to cleanliness, I still have wonderment on how your people keep the shop areas so clean. We work on this in my shop all the time and we don't compare to your plants. It is great news to have a business that takes such pride in building engines and transmissions the way you do! - Miller B.

This is a note to tell you guys how great you are! I drive a 1991 Pontiac Firebird here in Memphis, Tennessee. I had an engine installed that I bought from you all back in April of 2001. I've been driving my car EVERYDAY since then. It's a 3.1 V6 that runs like I just drove it off the showroom floor. I've got 240,357 miles on the car now... 113,507 on your engine. Most of the miles are city, but I do take a few road trips when I can. I keep the oil changed, just one set of plugs and wires, and I couldn't be more pleased with the way it runs. It never "misses" or gives me trouble whatsoever. The best part is out on the open road... 70, 80, 90 is a smooth as a Cadillac. I guess I just wanted to tell you that you're pretty good at your jobs. Jasper Rules!!!

We at J.R.'s Auto Clinic now have a better understanding of what goes into your finished products, and for us there will be no other. - Donald M.

I just wanted to share my experience with your product. I had a Jasper engine and transmission installed in my 1989 Chrysler Le Baron. Within two months of installation my son and I put your product to an extreme test by driving from Chattanooga, Tennessee to Prudhoe Bay, Alaska and then back home via California in only three weeks time. Your engine and transmission performed flawlessly whether operating in the snows of Antiqa Pass (with its 12% grade) or in the deserts of California, Nevada, and Utah. We went from sea level to several thousand feet in elevation without using a drop of oil or experiencing any problems during the almost 11,000 miles we traveled. All I did was change the oil and filter every 3 or 4 thousand miles (depending on how handy a service center was) and changed the air filter. I bought your product because of the good experience I had with my 1970 Camaro's Jasper engine. Instead of buying a new car I saved thousands of dollars which could be used on such things as trips to Alaska. I'm hoping to repeat the drive to Alaska in the next few years but this time take the Camaro. - Steve L.

There is nothing better than selling a product I know is top notch. When I sell a JASPER product the customer is best served in value and quality. Thanks JASPER for the attention to detail and the unrivaled customer service. Both of these create a sale time and time again. - Bryan K.

I have depended on Jasper for heavy duty truck, bus transmission and rear end rebuilds for many years. I can say that I have never seen any defects in workmanship on any work they have done for me. Jasper was very dependable in these items, B 400R, 4R100, Dana 60,70 series, 6V92TT. The factory tour was great, wish it was longer, talked to many factory associates while I was there, they were the best, you have a wonderful group of caring people, no wonder you have great products to offer. Your products would rank the best. Your plants are the cleanest I have ever seen. Housekeeping is 100%. All people that do any kind of work in the Auto, Truck, Bus related fields should come to your plants to see first hand, on what a good product you have to offer. Would you please see that he gets it, as this is my hobby. I am a rail car owner and operator. I would like to come back to you plants soon if I could. - John M.

We here at Dura-Bilt/Sonora Transmissions would like to take the time to thank you for your commitment to excellence, and as Jasper calls it the "Perfect Product". It is truly refreshing to do business with a company that stands by their word to deliver a quality product with a GREAT one hundred thousand mile warranty, on time, when promised. The commitment to customer satisfaction is unsurpassed. We look forward to continued success with Jasper Engines & Transmissions. To other companies that are looking to improve their bottom line also, consider these facts.  - Dura-Bilt

I do business with Jasper because the quality of their parts is second to none, or that they always say yes to my requests or that they give me free stuff. I do business with Jasper because they are good people. They work hard. They call me back. They do what they say and when they make a mistake or don't deliver what they said, they call me and tell me. From the folks who take in the cores and disassemble them to the delivery truck driver, each and everyone we've met over the last few years, acts like the kind of person who clearly knows right from wrong and has our best interests in front of their own. As a shop owner and media personality for the last 30 some years, I can tell what the administration of a repair shop is like, by reading their response to a written complaint I've been asked to arbitrate. As Sister Mary used to say in Catholic school, "if the top is rotten, so is the bottom." Or "If the bottom is rotten, it is because the top is too.". Most of us can identify with that. So because we interface with only the mid and lower levels of Jasper staff, I can promise that the top is fair, ethical and honorable and those ideals, those processes, those skills filter all the way to the bottom. Yea, I like what Jasper produces, that makes us look good to our Customers, but I do business with them, because of their staff, their employees are simply better than the others. - Mark S.

I would like to extend my gratitude and thanks to you, your associates, and your company for your hospitality during your factory tour. It gives me great pleasure to have been invited to join your family of associates for a day touring both your Indiana facilities. I gained not only a huge amount of knowledge from your tour about some of the processes and attention to detail that your company has value added to your product, but also an additional amount of respect for the commitment your company has to product quality, employees, community, and of course your customers. I have been in business myself for over 30 years. I have always strived for similar commitments as Jasper, however on a different scale. I must also commend the commitment, ingenuity, and resolve to keep a huge operation running with the efficiencies that are evident in every aspect of your operations. I totally enjoyed myself, and brought back with me more than I expected and would have ever hoped for. It is a great pleasure doing business with Jasper and its family of associates. - Daniel B.

I own a shop here in Plano TX and have installed many engines over the last 27 years. Engine replacement is a large job by any reasonable person’s standards. There are many things that can and do go wrong. That is why when you choose an engine builder, you really need to understand what you are getting. Jasper focuses on high quality products, and so do we. We stand behind our work, and I am glad to report that Jasper does as well. I recently had an issue with an engine replacement, and that issue was not discovered until the engine was completely installed into the vehicle. The issue required a complete re-do of the engine replacement. Jasper stood behind their product, accepted fault, and paid me the 20 hours it took to re-install another engine. They felt so strongly about their error that they even paid me my normal shop rate of $110.00 per hour. Jasper has re-stored my faith in their product, and I won’t hesitate to use them again. As a matter of fact, I ordered another engine from them this week. Thanks Jasper, you really impressed me. - Google Review

Best company. The atmosphere is nice, and their quality is unbelievable. I loved it. – Kaitlin A.

I have been doing business with Jasper for over 5 years. I have installed lots of transmissions and engines. The warranty department is helpful, and I have never had a problem with them. Great products and customer service. – Pedro E.

I recently installed a HD transmission in my F350. I currently have about 3000 miles on it pulling a 12000 lb. trailer and have had zero problems. So far, I have no complaints. – Robert M.  

I had a local transmission shop install a Jasper transmission in my 2004 Chevrolet Silverado Z-71. No more slipping and no more harsh shifts...it really drives nice! Thanks for a great product at an affordable price!! – Paul D.

I have run a transmission shop for 37 years. I have used Jasper for about ten years regularly. Generally, no problems and when there is, they jump right on it. – Rick D.

I have had the opportunity to work with the team at JASPER Engines and at every level of this company have found that they care about their product quality, their individual shop owner-installers and their customers. This company has been around since 1942 because they are unique in that specifically. It's why they work so hard to constantly improve their products and customer service and why they spend more time trying to earn that good review. It's also why I'm writing this review. If ever there was a GOOD investment, it is JASPER who provides a nationwide 3 year | 100,000-mile parts & labor warranty on most of their products. Also, you can readily talk to someone at the company where it is impossible to do so anywhere else. They are vested in doing it right and it shows. Look at their Facebook page and see what those who use their products are saying before you make a judgement based on a few reviews here online. Then look at the company website to find out more about the product or talk to one of the many-many shops out there who install JASPER and stand firmly behind it. - That many shop owners who work on cars all day long can't be wrong. – Marion M.

They rock! Always feel great after installing their product because my customers will be happy! – Mark L.

Have purchased many units from Jasper. If there has ever been an issue, they take care of it right away. Highly recommend. – Alexander M.

I am a Jasper installer and have had great success out of their product! True, occasionally, something will go wrong, but that will happen with anyone. Customer service is great if you do have a problem, so it is definitely a good investment. – Marcus M.  

We have been a proud installer of Jasper products for over 2 decades. We have always been very pleased with the products, service, and support they offer to us the installer. The best attribute they have is the Warranty. It is very comforting to us that when we sell their product, we KNOW it is backed 3yrs. or 100k miles. Also, that is nationwide and fully transferable. Now my customers have something they can count on. – Scott M.

Our shop has been an exclusive installer of Jasper products since 1998. We had experienced the products from the competition prior, lured by their lower prices and burnt by their lack of integrity as well as excessive warranty issues. We simply can't imagine a better alignment for our company. We highly recommend Jasper Engines and Transmissions products to anyone looking for the best quality backed by a real warranty. - American Pride Automotive

We are proud Jasper installers, we have used their manual transmissions, in medium duty applications, automatic transmissions in bus and motor homes as well as in light duty pickups and S U V as well as in both domestic and import vehicles. We install both gasoline and diesel engines. We have on several occasions done both engine and transmission replacements as a package. As with anything made by man, you can have complications arise. Jasper in these events takes care of whatever it takes to resolve the issue. Jasper is a "Great Partner " to have in today's complex market. I can proudly "Quote" a complete install with the needed components for as close to a like new, in the repair area. Cheap is not what we are installing. Quality and durability for the long haul is the real "Value". We have also sent in "Custom" part rebuilds, engine, transmission and differentials, that were not stocked items. – Ken D.

We have sold Jasper engine, transmissions, differentials and transfer cases for 16 years. These folks not only produce 1st rate products but they are professional AND pleasant to work with, they stand behind their products and their prices are very reasonable. We have rarely, if ever, had a problem with any of the many remanufactured parts we have bought over the years. Their technical service and help are also invaluable. Jasper blows away the competition at every level. – Jim R.

Great place to work for. Loving people who care about you and your future. – Josh S.

Been using Jasper for about 10 years, they have always taken care of warranty issues in a timely manner the few times I have had them. I have been to many different machine shops in our area and can safely say after seeing Jasper's plant that no one in my area has the equipment or testing procedures they do. Get a good reputable shop to do your work and they will have no problem dealing with any issues that might arise. – Emile G.

Happy to be an associate owner as we celebrate our 75th year of continuous improvement! – Ken W.

They have a great warranty, and they back it up with a nationwide parts and labor full warranty. – Kenny F.

Great products and great nationwide warranty! – R. K.

This is an upstanding company easy to work with, I have purchased other reman engines before, but it was not a good experience. I took a tour of this place and was impressed with their work ethic and commitment to quality. – Jerry A.

Great product, high quality, great value. – Jerry K.

Great company, great product! They stand behind their product and the warranty is awesome! – Paul D.

Great products for keeping my car running!!! – Stove S.

75 years of re-made in the USA. I have toured their facility and seen their process. If you’re in the area come and see what they do and why! – Dave B.
