Usually, transmission repairs are necessary because of a problem with one or more of the following systems:

"Excellent service! We are on a road trip, in a Jetta, and needed work done ASAP to make it in time for a wedding. We called a bunch of places, no luck. So we stop at autozone down the street and a nice man recommended Mr. Cool, and we’re so glad he did. We were a little lost on where to go not being from around here. We were back on the road within a couple hours. Thank you!"

"This was my first time here. I got my back light bulb replaced and it was fast and a good price. Everyone was nice and polite. The owner and her son were really nice as well. Definitely will be back."
"Mr. Cool is the place to go for my Auto A/C service needs! The floorboard on the passenger side of my car had been flooded all summer long and they took the time to unclog my drain not once, but twice within a two day period… and it only cost me the initial 1/2 hour of labor they originally had charged me. Definitely will be bringing back all my vehicles for any Auto A/C needs!"
"Best in town. I have been going to then for years. I have even bought a vehicle from them and it was in excellent condition. The service is great. Aaron is very knowledgeable and very detailed about his work. If you're looking for honest people that won't just push stuff on you. This is your place."
"Awesome place. I would recommend it to anyone needing any sort of AC work. They found my problems and replaced the parts same day for a great price."
