I was quickly informed of the issue and was quoted a price and set up with an appointment. I took my car back a few days later as planned. I took it at 7 just as they opened. I was unsure how long it would take because the mechanic, Rich, told me he'd work on it between jobs the last time I was there. I went home and they called me about an hour later that my car was all set and good to go. It was faster than I expected and not too much damage on my wallet. Very pleased with the prompt service.

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

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.

Here is an interesting story to show the absolute professionalism and expert work this repair shop…read moredoes. We were traveling in our 35' motor home from South Bend, Indiana toward the Chicago area on a Friday near the end of July 2017. The day before we noticed the transmission not upshifting properly and decided to have a Ford (it has a Ford V-10 engine) truck shop look at it. The closest shop recommended AC Transmission. We pulled into AC Transmission at approximately 10AM and talked with Tony the owner. He painted a glum picture after his men checked out the transmission and said we could possibly be back on the road the following Tuesday! We had to get my wife's brother and his wife back to Iowa where we'd met them two weeks prior, and we had to do it ASAP for them to be back home by the following Monday. After frantically arranging for a rental car, the wives began packing up all the clothes, etc., but little did they know they were being raised off the ground by the lift in the shop! In the meantime, Tony approached me and said that just maybe they could get us back on the road by the afternoon - amazing. He even loaned us his errand car to go out to get something to eat while they did the work. By 3:00PM the work was finished and we were ready to get back on the road. Oh yeah, the wives had been returned to earth after we contacted them via cell phone! But Tony and company were our saviors for the day and we are forever indebted to him and his crew. A repaired transmission in a 10 ton vehicle is no easy task. When we were leaving several of his workers came out to wish us fair voyage for the rest of our trip. What a touch. Those guys are the best. And the price was reasonable too.
