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!

I went to the shop for a transmission fluid change. They charge me 225. I look under my truck after…read morethe service, its bone dry. Doesnt look like they touched it or cleaned it or changed the washers. I go back to ask what they did and why the plugs dont have any new washers. Because they dont look like theyve been touched. Transmission fluid leaves residue and even cleaning with brake cleaner would leave evidence. The tech told me he filled it and drained it from the level plug. Which makes no sense because the level plug indicates its full and isnt a low point to drain the pan. He said he has special tools to drain and fill from the level plug. In my mind im thinking BS. I wanted a refund. I dont think they did the service but they charged me anyway. Dont go here if you value honesty and integrity. The feeded me bs saying the level plug which indicates is full is where they drained it. You can see from my pictures none of the bolts look cleaned or even touched. No residue of oil, or cleaner because it looks like nothing was done to it.

Had some major issues with my Jeep. Took it to 2 different places before Supreme. The first place was a scam. Second place the guy wasn't sure he could fix. This place charged less than the two others and fixed it all. Yippeee. Drives like new. Shout out to the mechanic Ronnie. I appreciate all your hard work! Highly recommend. Ten stars

Very disappointing experience with my Tesla Model Y. I specifically brought the vehicle in for a…read morecontrol arm noise coming from the driver side and clearly explained that upon arrival. The shop diagnosed and recommended replacement of both the driver and passenger lower control arms. I ultimately approved repair of only the side making noise for approximately $697 (versus the $1,394 they recommended for both sides). What bothered me most was that after the repair was completed, the technician test drove the vehicle, yet nobody informed me before making payment that the exact same noise was still present. I personally discovered it myself within less than 10 feet of driving out of the shop and immediately returned. The lack of communication regarding the unresolved issue felt very misleading and frustrating. Instead of taking ownership of the failed diagnosis or communication issue, the owner Elvis became defensive and stated the reason the noise remained was because I was "too cheap" to do all the work (both side, $1,397). He also suggested I should have replaced the upper control arm as well, despite the fact that they never diagnosed or recommended prior to the repair. I ultimately took the vehicle to the Tesla dealership, where the upper control arm issue was addressed at a significantly lower cost. While the lower control arms may have shown signs of wear, replacing worn parts that are not actually causing the customer's complaint makes little sense from a diagnostic standpoint. Based on my experience, the process felt more like guesswork than properly isolating the actual issue. Customer service was ultimately arrogant and unprofessional. Based on my experience, I would be very cautious bringing a Tesla here.

If I could give more than 5 stars, I would. KCC Auto and Elvis are the gold standard of what an…read moreauto shop should be--honest, knowledgeable, detail-oriented, and deeply experienced, especially with luxury brands like Porsche. After being let down time and time again by the dealership, I finally found a team I can trust. Elvis didn't just save me a huge amount of money--he saved me the typical headaches that come with Porsche service. I even stayed nearby for three days while they worked on my $100K vehicle because I knew it was in the right hands. This shop is a rare find. If you care about quality, professionalism, and people who truly know what they're doing, KCC Auto is it.
