A++ My wife and I had recently bought our daughter her first car and my instant thought was to give Wally a shout. Being an older car, there was some work to be done. The turnaround time from drop-off to pick up was phenomenal. I am not a "car guy" so Wally and his team walked me through the process step by step explaining his teams findings along the way, which was invaluable for me. 10/10 recommend! Thank you DuPage Transmission Service! read more

From start to finish, this was the best car buying experience I've ever had. Eddie OLVERA is the best car salesman I've ever worked with!! read more

Dupage Transmission Service, Inc. - Husband at Huntley ford - Auto Repair Near Me - Lisle, Illinois

I can't explain how amazing this shop is, no matter what, you can be sure that you are being taken care of. Everyone is so on top of it, you can feel safe in the hands of dupage transmission. My car broke down on the Dan Ryan in Chicago, I was freaking out, it was smoking. I called dupage trans and they had me call AAA and send the car to them. The owner Wally took a look immediately, even sent me pictures of the problem. Fixed my car and it was ready the next day. Absolutely unreal. read more

Very nice got me in quickly and didn't over charge me for work. Attempted to find parts no one else could. Would definitely return

we took our car in on a Tuesday expecting to have it out on a Wednesday. We were told the problem was a tuneup when we already had it tuned up. We were hoping at this point that they would pull the car back in to re-diagnose, but were told that they already ordered plugs and that seemed to be the path they were sticking to so another day went by by now we are on Thursday. They then re-diagnosed it and said it would be ready Friday morning. We get another call on Friday morning saying another misdiagnosis. We lost 2 1/2 days. We finally pulled the car and took it to our local mechanic. Very disappointed in how this was all handled. read more

Had a timing belt replaced on my 2007 Subaru Forester ($1200). Less than 10,000 later, the belt broke, destroying the motor. The owner refused to stand by his work, resulting in my having to donate the vehicle. Especially disappointing because I had previously had work done at their garage. I would never recommend them. read more

High quality run business. Great communication and highly knowledgeable. Scott and Wally are honest and efficient.

I have a manual transmission car. You might think they are easier to fix than an automatic transmission car but they are far less common so the body of experience fixing them is not as great and the availability of parts is much less. I had my transmission rebuilt and the clutch replaced at 190,000 miles. It shifts as nicely as when I first bought it. Thank you DuPage Transmission Service. read more

Scott and the guys at DuPage Transmission did a great on my Toyota and working with the warranty company I would work with them again for sure. Steve Quinn read more

Wanted to thank Scott and DuPage Transmissions for an outstanding service experience. My 2007 Mustang GT had a new onset transmission problem and from the minute I spoke with Scott he gave me an honest breakdown as to what would need to be done and a very accurate quote. I was kept in the loop throughout the repair. This is a business I highly recommend to anyone who is in need of Trans repair or any other mechanical issue. You guys are top notch !!!! Ken read more

Serviced my transmission, 2008 Sienna, 2013, 100k miles later, more trouble! Not the transmission. Broken axle. Rebuilt transmission still going strong, 260k miles. Great shop, friendly and responsive. We have many high mileage cars. And a great repair service. Ted read more

I have another wonderful experience dealing with DuPage Transmission of Naperville. My daughter left for Iowa City on Friday for a friends graduation weekend. While enroute to Iowa she stopped at the Decalb Oasis for fuel. Uppon leaving the fuel pump the car started bringing and would not shift into park and the car was inoperable. She called in a panic and told us what was hapening. Our daughter doesn't deal with these situations awesomely and threw up. I told here to engage parking brake and turn on the hazards. I would be on my way and will be there in less than 30 mins. As I got there I see she is stopped in the middle of the driveway parking lot and causing a backup at the oasis. I approach the car and ask her to turn off the ignition. "DAD I CAN'T" is her response. I show her how the shift lock over ride is used and get the vehicle into neutral. We push the vehicle into a parking spot and remove her personal items, leave the vehicle unlocked and head back to Naperville. While driving back to Naperville I call Dupage Transmission and speak with Scott. I explain the situation and he gives a suggestion of a flat bed tow company. "Get it towed and we will get it fixed today" Wow a shop willing to stop their other projects to get me back on the road asap! The vehicle waswas back on the road same day and my daughter was able to not cancel her weekend. A true mom & pop establishment that only cares about their customers. This was such a pleasurable experience that I had them complete a few other maintenance items I've been putting off. The vehicle is ready for another 90k. If you want an experience like this with your vehicle repairs I suggest using DuPage Transmission of Naperville. Many thank yous to Scott and his team read more

Wally goes above and beyond when it comes to repairing my car. A notch above the rest! Thanks for the good work, great price and awesome customer service. We were very pleased with the job Dupage Transmission did. We will be back! read more

Wally is great!!!! He treats his customers fair and with respect. Great prices and the turn around was quick. Will definitely be back!

Love this place!!!! I changed the front brakes on my fiancés car and she was convinced that I had done something wrong because she heard a "noise" that was't there before. I called Wally and asked if I could bring the car in for him to take a look. I was on a tight schedule as I only have 1 day off per week. Wally had me drop the car off and I went out to grab lunch in the meantime. The place was packed and had a car on every rack and I thought it was going to be there for more than a day for sure. I got a call from Wally no more than 3 hours later letting me know he had taken a look at the car already. He had quickly diagnosed a loose hub cap and a dented rim. He even took time to lube the back of the new brake pads I put on. He is a great guy and runs a great business. I would refer any friends or family to him for ALL automotive needs. The name might say Dupage trans, but they do everything!!!!! read more

Scott, Wally and gang have always come through with flying colors when it comes to servicing our cars for the past 15 or so years. They are always right on top of the service and communicating with us about exactly what they are doing. Quick, courteous and honest. What more can you ask for. Kudos to Dupage Transmission! Thanks. read more

I have used Wally and Dupage Transmission (countless times) for 12 years for all of my auto repair needs. He and his guys are honest, attentive and clean. I have referred them to all of my friends.

If you are looking for great people who provide expert advice and service, this shop is the place to go. The Service Mgr. (Scott) is one of the most down to earth, sharpest, and most honest guys you will ever meet, and his expertise is impressive. In an industry filled with incompetent and not trustworthy people, Scott and DuPage Transmissions rise way above the pack among auto repair and transmission shops. I highly recommend them. read more

The service here is impeccable. My summer schedule is very hectic and caused me to be out of town for about 3 weeks. All the while the kept my car and didn't charge me a storage fee. If you have any issues with your car and live in the Naperville area take it here. I will for sure be a repeat customer, hopefully just not for a new transmission. read more

Wally always goes out if his way to provide great service!

Wally and his team at DuPage Transmission are courteous and professional. They provide excellent, quality service and make sure that you're satisfied with the work they have done on your vehicle. read more

Brought our car in yesterday to have a few things looked at. Scott was prompt efficient and just generally a nice guy that took care of everything for a fair price. It didn't hurt that I had purchased the $25 off coupon before paying to help offset some of the cost. Would most definitely return for service again if necessary. read more

Scott was awesome! He checked out my car and explained everything that needed to be done and what the cost was going to be... He was super patient answering all my questions (and there were a lot of questions) ! I feel like they were honest in telling me what was wrong with my car and what needed to be fixed now and what could wait a little while. I will recommend them anytime I get s chance! read more

Outstanding service. Wally the owner and Scott are the best. They were very fair in their assessment and their pricing. Highly recommend to anyone that has a car. read more

Had taken my wife's '05 Explorer in for a trans rebuild. It had a 2 year warranty that expired in November of 2017. Had some problem with trans in January 2018 and learned that trans needs to be rebuilt again. What a disappointment. 2 months out of warranty...and POOF. And a lot of money was spent here since I had two cars with trans problems done here within 2 months of each other. read more

Wally and his team have done exceptional work for me and my fleet of painting vehicles, as well as my 67 Oldsmobile Toronado....when Wally got done with it, i was confident to drive it to Arizona! Oh, btw, he says, we painted your engine and trans while we had it torn apart, in the original colors, thanks for going the extra mile Dupage Transmission! read more

BUYER BEWARE! we spent $2k Nov 09 for a transmission overhaul and was given a 2yr/24 k warranty we took car in several months ago because while we were having tires put on our friend pointed out that the plug from the transfer was missing; we had never had any work done prior to this and took it back to DuPage trans ; they put in the plug that wasnt there! and charged us for part and time; now transmission is doing the same thing again; wont shfit from 2nd to 3rd and we contacted Wally (owner) he said to bring it in; then he had one of his workers call to say since it is out of warranty and past the miles he can't do anything about it; except Overhaul it AGAIN!!! and charge us another 2 THOUSAND DOLLARS!!! so in a nutshell.... its going to cost us 4 plus thousand dollars in less than 3 years thanks to DuPAge Transmission! we took the car to AMOCO and they willl do quality work for the same amount with a 3 year warranty. Wally obviosly does not care about his customers or stand behind his work.I will also be reporting this to Better Business Bureau read more

Excellent and fast service, accurate quote (actually, came out a few bucks cheaper than the estimate!), and all around great service!

Prompt, thorough, honest and excellent service. I also appreciated the recommendations and things to look out for. Terrific customer service. I will be back. read more
