"I had the transmission go out on my Ford Escape and luckily it broke down next to this shop. Steve gave me a free evaluation and helped me keep my cool in this stressful situation. It ended up needing some internal fixes and like with any transmission with internal issues it was going to be costly. I was never pressured into getting it rebuilt there and quoted prices that he held his word on. My car was taken care of, I can tell the shop took the time to do the job right. My car is running great again and it's nice to have a warranty for an additional peace of mind. Would recommend to anyone looking for a professional transmission shop with honest service."
"These guys fixed our transmission. They did a great job and saved us over $1,000! My husband and I are very happy with them. We will return for other auto maintenance."
"Cottman did a great job replacing my clutch. Best price in town and could not have been more thorough."
"I had my engine oil & transmission fluid changed at a local Round Rock oil change business. I saw the manager and technicians fumbling around, so I asked what was wrong. The manager told me they were trying to remove the "change transmission fluid" message from my Saturn information display. After 45 min. of fumbling around, they told me my car was ready, and that they could not clear the message. The manager's advice was to go to a transmission shop to have it cleared. I went to COTTMAN of Round Rock, and Steve found quickly the technical data to clear the message, at no charge. I believe next time I will see Steve about further transmission service."
"Our SUV broke down on a cross-state family trip. We basically glided into this transmission shop. They were able to diagnose and repair the serpentine belt (pretty obvious since it was completely missing, haha) and repair it for a fair price. John, the manager, was very courteous and didn't mind our two little girls making a raucous in the waiting area. Plenty of shops would have tried to take advantage, but I feel that they were completely fair and got the job done as quickly as they could for us. Thank you so much for helping us out! It could have been so much worse if we didn't break down right where we did! :-)"
