Transmission was going out on my husbands car. Called and got me in quickly and installed new transmission and now runs like a dream. Prices was fair and if I need transmission work in the future I will go back . Definitely recommend. Thank you

Great place to take your vehicle if your transmission is having issues. They put their diagnostic fee towards your final bill if you decide to have them do the work. beforeThey rebuilt an F-150 transmission for a friend of mine more than 5 years ago, and he's never had an issue. They are more than competitive when it comes to pricing and service.

Honest and excellent! I've had them check out a couple of vehicles over the years - one just needed a part replaced and the other was a full rebuild. In both cases they were surprisingly faster than anticipated. Fair pricing as well.
