I recently had the transmission on my Ram 3500 fail and took it to this shop for the first time. Their team did an excellent job, listening carefully to my needs and rebuilding a reliable, well-performing transmission. The result is smoother and more precise shifting than stock. Their craftsmanship and attention to detail were impressive. I highly recommend this shop to anyone in need of quality transmission work.

Took my pick up truck, and told him the problems it was having. I’m happy with the work and the time it was done.10/10 would recommend. Everything went smooth.
Leroy Posas
Shoutout to Tello he doesn’t play around from the moment I got there everyone was busy working I told tello what I needed he confirmed that my car would be out by a certain time and the job got done by the time he told me. Even when I arrived to pick up my car everyone was still working and busy, I paid what I owed and Tello and another worker spotted me while I backed up to leave the shop to make sure I got out safely from oncoming traffic. I will definitely come back if I ever need or someone that I know needs a transmission worked on 💯
EJ De Leon
Excellent service was out less than an hour. Fixed the famous and common shuddering of GM issues and changed my engine oil. Friendly environment and he puts all the parts he tells you unlike other places I've gone. 100% recommended will be my shop to go for service on my trucks. Thank you Juan & your Crew!
Roberto Mendoza
