His expertise, advice, and generosity were beyond belief. Mike made sure we got back on the road as quickly as possible. Living in NC, I will probably never see Mike again, but I can truly say I have a friend in the transmission business.

I was hesitant to give the details of same day service in an emergency but it happened again! UNHEARD OF to have it fixed in one day! I believe my son said the woman's name was Leanne that fought with the warranty company for them and GOT IT! I thought that we had hospitality here in the south but MOUNT VERNON, ILLINOIS has a GEM!!!! If I could give this company TEN stars I would do it. As a Mom, I was actually crying because I am so grateful to this company of hard working employees which is so rare to find. They would have had to either leave the truck & trailer to come home for work in her car, stay in a hotel or we would have had to drive him back to Illinois then come back again to Virginia. M&M Transmission...you are the best!!

I took my 2005 Ford Escape in for rebuild July 2 2015 and was given a 3 yr warranty. I took my car…read morein on May 24, 2018 with reports that I had lost reverse and the other gears begin slipping. I received my car back on June 13 and was told the seal had been replaced. I return the car back to the shop on June 18 with reports that the slipping continued. I picked up the car, for the second time on June 27, being told that the bands had been adjusted. On June 28 , while driving on interstate 57, the transmission had a complete blowout, less than 24 hours after I pick it up from the shop. I called Clay's transmission and he told me to have it towed in there and He would see what was going on. The tow bill was $126. Six weeks later, on August 13, I receive my car back for the third time, having been told that the transmission had been completely re-built. I drove the car to St. Louis and back to Southern Illinois. When I parked the car everything had run fine. However, when I started the car up, there was a a clanking noise under the hood. I immediately shut the car off. My 32yr old son got out and looked under the car and had me restart it, the clanging noise stopped and one of the transmission bolts had fallen out. It was stripped and bent. I returned the car to clays Where he told me he could see oil leaking out and they would look at it again. August 22 I returned my car to the shop for the fourth time. It was not available to pick up until after Labor Day. When I picked up the car, the owner and I discussed the tow bill. After going back and forth he finally agreed he would pay the tow bill. It is now November 2. I called my towing company, who said clays transmission had called him and said he would be sending a check in the mail, but they had never received it. I contacted clays transmission and spoke with the owner who told me once again, " I will take care of it, but it just slipped my mind" I'm giving this company a 2 rating because they can do good transmission repair, but 1. The tow bill hasn't been taken care of and it had been 2 months since I picked up my car 2. The stripped transmission bolt was shoddy workmanship( it had been taken in and out too many times. 3. The drivers window will only go halfway down now, ( this happens because the door gets slammed to hard and breaks the plastic pieces on the inside. 4. I have not received one piece of paper ( receipt) showing the work done on my car. Now it's August 2019 and guess what!!!! My transmission slipping going into 3rd gear. I've babied this car so much trying to get it to last as long as possible. The other update is once I contacted the Better business bureau 3 months after I had gotten my car back, Scott( the manager of clays transmission ) did go over and take car of the tow bill.

Shortly after getting back on the highway, my "check engine" light came back on. I was debating whether or not I should go further, but pulled off the road at the next exit, which was Mattoon. After stopping at the first auto shop, which did not do transmission work, I was referred to CIT. After getting there, they quickly diagnosed the problem and gave me several options. I had to leave my vehicle behind and come back for it later. They did excellent work, and I was extremely happy with the quality of work done, and how they helped me. Very trustworthy people. Although I live several hours away, if I needed something done with my transmission, I would consider going the distance, knowing that it would be done right.
