What an amazing group. Where do I start. Punctuality and communication with fixes over the Holidays 5 🌟. Friendliness 5 🌟. Work ethic 5 🌟. Thank you for going above and beyond to fix my parents Yukon. If you are in need of transmission work. I highly recommend ATSI of Lawrence.

Great shop! ATSI replaced the transmission in my car over a year ago and shes still running strong. They stand by their work and are willing to go above and beyond to make sure the customer is satisfied.

Hands-down the best transmission shop in Lawrence Kansas!!!I have a 1986 GMC Vandura Short Bus,And Dwayne has kept my bus running throughout the years he was the only one that can fix the transmission so perfectly thank you so much ATSI!!

Duane is really great. Had a problem that he went out of his way to make sure was fixed, and fixed right. Even called me up a few weeks later to make sure it was good. Amazing to find good service, make that great service this day and age.

Great guys doing great work

These guys are awesome. Had a tricky problem and they kept on it till it was done perfectly without flaw. Very nice, and even called in later to see that it was still functioning properly

I received a referral from Midwest mustang for transmission service .

Great work and fast job!

I had no idea what a CVT was; they explained it, priced a new one for my vehicle and helped determine that the condition of my car was worth repairing instead of replacing. They are wonderful. Cheryl was super patient in answering all of my questions and keeping in contact as replacing a CVT isnt a quick thing to do.

Very knowledgeable & friendly

Took my sons truck in to check what was wrong with transmission. Transmission had a warranty from another company wanted ATSI to look at it to tell me whats up before i contacted the people i had an warranty with. Duane found what was wrong with it same day. He never once tried to sell me a transmission until I asked him what he would charge to rebuild it. Waited a week for the company i had a warranty with to call me never got a call back. Said the hell with it. Send it to Duane he got us fixed up with a rebuilt one at a reasonable price and fast. Thanks Duane!

Best customer service in the automotive industry and the quality of work is top tier.

Friendly service. Actually honest that service on my vehicle wasnt necessary. Only got a 4/5 because they didnt call me when my vehicle was ready; potentially because of a miscommunication.

Good service,

They are upfront and honest from the start. Theyve got some of the most reasonable prices and they have the best warranty around. Couldnt be happier with their work!

These guys are amazing!! Went way out of their way to find the parts for our Mazda CX-9. They were calling dealers and parts centers all over the country. Calling us with regular updates. Car was delivered clean and drove like new!! Prices are also reasonable. My first stop now for auto needs!

Highly recommend! Lost a gear over the weekend while traveling and they had me back on the road with a new transmission by Tuesday afternoon, which is less than 2 full days of work! Super friendly, great prices, answered all of my questions, honest and kept my truck safe while it was at their shop.

I have taken my vehicles to Duane, the owner of ATSI, for nearly 15 years and have recommended them to all my clients, friends, neighbors and family. Not one person, NOT ONE, in all that time has ever had a poor experience. They go above and beyond in terms of service and quality. I cannot say enough good things about them. Duanes honesty and integrity are above reproach. He may not always tell you what you want to hear but it will always be the truth. What more can you ask for!

They are really good people. Great transmission work. Would reccomend them to everyone.

I have been going to ATSI for 10 years now and I have been very happy with their service. I was recommended by a friend. I am a business owner myself and understand good service. These guys have it!! Keep in mind good service isnt always perfect service. These guys make mistakes but they stand behind their work and thats what counts. I will always use them. keep up the good work Duane. Thanks Jacob.

Decent place. Honest people. They replaced my car transmission solenoid very professionally. However, they moved my drivers seat backward and now I cant move it backward.

These guys rock! Saved us when everyone else said it would be a week. Got us up and running. Got home thanks to these guys. Honest and straightforward. Go here.

Terry has serviced every car my husband and I have owned for the last 35 years. He is a brliant master mechanic! Each of our 4 children shared the same 1990 Honda during high school - a span of 10 years of teenage wear and tear - and it is still driveable today thanks to Terry. He and Dwayne, the owner, are experts, professional and take the time to answer my questions so I have a thorough understanding of my cars condition. They are the best. Its rare to find people that have such longevity of trustworthy service. They can fix anything.

What in the hey! They have had my car A WEEK. For a sensor. I can’t call them and get information because I have a loan out on the car. So they have to talk with the dealer “they don’t answer to me they answer to the dealer”. I don’t honestly understand how that’s even a thing?? They kept it passed my thirty day warranty with the dealer so I’m sure I’m screwed there. It’s ridiculous. I call the dealer he tells me one thing I call the shop they tell me another. I honestly am just annoyed at the process.

Ive taken several vehicles to ATSI for repair. The repairs have always come in below the estimate. They have the best warranty in town. They are easy to work with, if you have an issue with a repair. Their integrity is top notch.

Good Honest Mechanics - Always Get the Job Done Right!

Great service highly recommend

Best repair facility within fifty mile radius

We had a total transmission job done. The cost was exactly what was quoted and was completed as scheduled. The staff were all friendly and helpful.A few days later I had unrelated car trouble at the gas station next door and they came to my rescue with a smile.Highly recommended!

Very rude. Does not do gd work or stand by it

Wonderful great fast service called and told him did I have a problem with my vehicle they said bringing in early will fit you in they got it all done in one day cannot ask for anything more than that great people working there definitely recommend them

If you dont feel you get five star service you should just talk to Duane. Its so much more productive than posting a bunch of half truth stuff on the internet . 3 years 50,000 mile warranty on all repairs. 3 year 100,000 mile warranty on all transmission overhauls or replacements. Just ask your friends and neighbors. Its real.

Delivered before promised and under budget! They took the time to discuss the issues with me and to help me understand what was going on.

Great shop! They do good work and they are trustworthy. Thanks!

ATSI helped me when my 2003 Chevy Avalanche transmission failed in 2012. They were exceptionally professional and worked with me to understand the costs and what they were going to do in the work. When it was all said and done, they actually charged me a bit less than the original estimate. They could easily have charged me the estimated price and I wouldnt have know a difference but they showed their clear ethics by charging me what it actually cost. This is a very refreshing way of dealing with your customers that I wish all auto dealers and repair shows would hold. The transmission has been doing phenomenal and havent had any issues in the five years since their repairs. They are a great company. Thank you for all your help ATSI.

Great guys. Fixed my speedometer issue, very reasonable.

Very Poor Attitude. That best describes the man who works 80 hours a week at the counter with whom I spoke today. Very unprofessional. I asked for advice and help with the transmission Im putting in my kit car and he got angry with me for no reason. I have never been treated so disrespectfully. I had a couple questions and he treated me like a piece of crap. I nearly walked out in the middle of what I wont refer to as a conversation. This was my first trip to ATSI and I will never return because of his disrespectful and poor professional attitude. Im disappointed. I strongly recommend taking your car and questions elsewhere.

Great staff! Thanks for all of your help!

Went here to diagnose a transmission problem. Left it overnight and they said they would go into the transmission and find out what the problem was and come back the next day. I came back and they gave a recommendation without actually going in and looking at the transmission. Wouldnt recommend.

They know your tranny inside and out. They will fix or be honest with you

Great service and great overall experience, always recommend them to anyone who needs quality work done, Duanenand his crew knock stuff out and keep alot of people happy they have built 2 transmissions for my family and im very impressed

Good place to get car fixed reasonable and friendly

I took my car to a reputable dealership to work on it in the automotive department and they told me I had a cracked cellinoid block and wanted to charge me 1000 to fix it. I took it to ATSI and found out that cracked cellinoid blocks would spray oil all over. These guys were fair, honest, and well priced. ATSI are the only people I will let work on my car.

GreatServicesGood people.They tell you everythingThat needs done to be done before doing the work. Very professional.

Duane and the guys are organized and get it done. Having a technician at the front desk makes a big difference to me, Thanks Mike!

They did a full transmission rebuild on my 1986 GMC short bus for around $2100 they did excellent work the transmission rides like a dream good job ATSI

Mike and Terry are great. Fast, friendly, efficient service.

I needed my transmission replaced on my 2000 Toyota Celica and brought it in to ATSI after it sat parked for almost 2 years. After all the sitting (and the miles 220k with most parts still OEM), I had some cracked hoses, a bad thermostat, a leaking rear main seal on the engine AND needed my transmission rebuilt! And yes, it sounds like a lot, but I did know that all of those things were needing to be done, its an old car.Because I did decide to tackle all the work at once, they were able to give me a great price on the rebuild and all the other work, saving me cost on the labor. They were also the only shop in town willing to do a rebuild and not just install a brand new transmission, which saved me more money.Car is running great now and even when I thought I had an issue creep back up with it 2 years later, they checked it out for me at no cost. Ive been very happy with the team at ATSI and would definitely recommend them to anyone needing auto work.

Great friendly service! Had my car back in two days, they fixed the problem and didnt charge me an arm and leg for it!

Knowledgeable staff and good to work with.

Today I am one happy customer Dwayne and the ATSI team really went the extra mile literally & they absolutely 100% stood by their three-year 60,000 mile warranty on my transmission rebuild, please allow me to explain why Iam so excited and pleased with ATSIs transmission service .OK here we go .... So about lets say two weeks or so ago my front brakes on my 1986 GMC short bus locked up on me while I was driving down E. 23rd St. almost towards Haskell Avenue I was in a rush that day so I left the vehicle on the side of the road the very next day I believe it was Saturday or Sunday I think it was a Sunday I couldnt find any other shop that was open so I called around and lo and behold the shop that was relatively super close to where I was broke down at was open on the weekend its called Harris Auto Great folks there as well, so I take my vehicle to Harris auto and they perform a full frontal brake job I mean they replace entire breaking mechanisms cost$1300,on the front and while they were doing that they located a transmission fluid leak was leaking red transmission fluid, i told Harris that I had recently gotten my transmission rebuilt at ATSI transmission specialist about a year or so prior, & when I told ATSI about my leak they immediately & without any trouble,any grief or hassle or runaround told me that they would come down to my house and take a look at the leak when they got to my house they noticed a leak in took my vehicle to their shop & fixed the leak without any charge after they fixed the leak, hears the good part while test driving my vehicle the front brakes locked up on them, Dwayne called me and told me that the transmission fluid leak was all fixed free of charge because it was covered under my warranty and that the brakes had locked up on them and they bled the brakes to unlock them and would go the extra mile & take my vehicle to back to Harris automotive shop so that they repair whatever wrong with the front brakes because they had just redid the brakes in the front . ATSI did all that extra work and did not charge me one penny so Im here today to say that I am very pleased and I want to think Dwayne & the team at ATSI transmission specialist .

Great staff, fast and good service

Awesome!

The best of the best!

Good service,
