Heavy Duty Vehicle Repairs

At Lou's Wolverine Transmission and Auto Repair, we understand that time is money, and if your heavy-duty vehicles aren't out working, then you aren't earning. With this in mind, our highly trained and dedicated workforce will quickly diagnose and repair any problems with your commercial vehicle's powertrain, hydraulics, electronics, braking systems, or any other component vital to the smooth operation of your business. While light-duty repair shops are common, it's harder to find technicians with experience in heavy-duty vehicle repair.

Another area of specialty at Lou's Wolverine Transmission and Auto Repair, is the work we perform on stricken tractor-trailers.

What Our Customers Are Saying

Lou and his team are unbelievable. Not only do they do incredible work but they are also incredibly fair and will have no problem telling you what should be done rather than what will make them the most money. They really care about the customer. That's why my family and I refuse to go anywhere else for service. Lou is the only place to go, in my opinion.


-Jonathan B.

Lou did a great job on my truck! He was very professional and punctual in working on my vehicle and getting it back to me in a very timely manner. I found his prices to be reasonable. I appreciate his keen insight in addressing all of my concerns, without any additional charge. I will be going back to him and highly recommend this place!


-J. C.

If you're looking for a good auto shop that specializes in transmissions and drivetrains, stop searching. Not only did they fit me in on a busy afternoon, but they returned my car same day, fixed the issue I was experiencing with my AWD subie, and did it all at a fair price. No surprises, no additional services, just a solid experience. I can see why Lou's has been an Ann Arbor institution for 20 years.


-L & J

Great prices and amazing service. Not just transmission work but all maintenance. Thanks again


-Stuart K.

Dan is a great guy who treats you fairly.


-Mike B.

Took my Buick there with transmission problems They were very upfront, helpful. They've been there forever and had great reviews. And with good reason. They do quality work and know what they are doing. Will try other things before overhauling if they have a chance to fix it. In my case a Trans flush & cooler (Very reasonable price to do it and I wanted to have one anyway). Trans was OK for a while but went back to not shifting right. The did a complete overhaul and at less than I feared. What are you gonna do? You can't throw away the car... Other repair places offered to do it but if I was going to do it I wanted someone that did it every day. Very happy with them and glad they are here in town. Oh, I didn't know as a Veteran I got a discount but they saw my Military licence plate and gave it to me without asking. That's Honest!


-Gary D.

Lou's staff from front end to back in the shop is PHENOMENAL. They treated me with the utmost respect and were nothing short of honest and transparent the entire time. Even after I paid for a complete transmission rebuild and still had problems with my 2009 Equinox, they held onto my car until they were sure they had made it right - free of charge. I would recommend their services to anyone with transmission issues.


-Kyle B.

Lou (and now Dan) always take care of me. Honest and quick. Thanks guys!


-Frank T.

I love the guys at Lou's! Dan always goes out of his way to help me save money and provides amazing service. Being a female, I have a hard time dealing with shops because people assume I don't know anything about cars and I've lost count how many times someone tried to pull the wool over my eyes. I know I can trust Don and the guys. They get you in and out and the pricing is beyond reasonable. I won't take my car anywhere else!!


-Leigh S.

Lou retired. The business is now owned by his Nephew, still out standing service and will still continue to use for repairs I'm unable to do myself or don't have the equipment to do. I had a second vehicle that had trans axle problems around January of 2018 and I took it into him. In 2013 I had the transmission for my 1998 ford ranger rebuilt. Two years latter, the transmission is still going strong.


-John N.

Had a catastrophic failure on the transmission of my old Explorer. It honestly looked like it might be totaled. Had it towed to Lou's, they jumped right on it (even though it was the Friday before Christmas). Replaced the leaking cooling lines, verified the tranny was still good and had me back on the road in just a few hours. Life savers.


-Kent K.

Lou got my trans replaced in my Super Duty in less than a week! My truck drives like a champ now, I cannot recommend him enough! Was straightforward, less expensive, and quicker than any other shop!


-Jeremy H.

Lou's has been GREAT to me every time Lucille (my car) has needed repairs. Courteous, friendly, knowledgeable & just good people work there. Rebuilt my transmission a year ago & she's still running good. No complaints whatsoever about Lou's.
