Customer Testimonials

If you're like me, you know that going to an auto repair shop can be extremely frustrating. Whether it's the rude and/or condescending attitude of the employees, the plethora or random, unorganized nuts, bolts and other various car parts, or the overall shady-ness of the place, it's no trip to Disneyland. Well now i have discovered that it CAN be like a trip to Disneyland! At DMC Transmissions, you find nothing but skillful and educated people. People who won't try to rob you or sell you something you don't need. Everything is neat, tidy and in order. I brought my car in a couple of days ago and was treated like a king. I got great quality service, friendly conversations/interaction, and a car that drives like never before. Big thanks to Donny, Susie and Nieves for all their help. You have yourselves a loyal customer with me.

I have a Chevy Silverado 5.3 (LM7) chipped with some centerline 20's, ive been breaking and fixing alot of things on this truck... one main thing i wanted to rebuild was the tranny so i had a shift kit and a shinny billet servo installed with everything else stock, come to find out WOT one to many times completley shredded my output shaft, and i even cracked the housing.. DMC was ready and set to help me with a new DMC 4L65E with my competition shift kit and Billet servos..She runs like a chanp beating ricers to fords...THANKS DMC!

I recently had my car examined at DMC after noticing a loud noise coming from the engine area. They discovered it was an expensive powertrain issue and the repair would be costly. Instead of trying to convince me to go ahead with the repair they advised me that I would be better off getting either a new or quality used car. They even provided me with a few contacts to help make the search easier. Their honesty is very refreshing and I will take any future car I may own there because I know they will be truthful with me.
Thanks DMC !

I own 2006 Sienna van with as I found out a notoriously troublesome transmission U151. After being told that it has to be rebuilt by virtually everyone I called. I was fortunate to talk with Donny at DMC. He had the knowledge and experience to test and see that a rebuild wasn't necessary. His honesty and skill level knowledge of the transmission saved me thousands and I can't be more satisfied.

The guys (and gals) at DMC are truly in it to help their customers. Fair and thorough, they really do go above and beyond to troubleshoot and solve problems! Thanks!!!

Friendly, professional, honest, quick, fair price, excellent work. Would certainly use again.
