About Competition Transmissions

In 2001, after many years of transmission repair experience, Carlos Hernandez started Competition Transmissions. Today, the shop is the favorite Santa Clarita transmission repair shop in the valley and surrounding areas. We have such a strong reputation, we have customers who come to us from as far south as San Diego for their transmission repair and transmission service.

We’re proud to serve the community and we appreciate your referrals. We believe the best way to grow our business is give you the best and most affordable service available! With our large inventory of transmissions and transmission repair parts, we have become the trusted go-to source for transmission repairs and rebuilding for numerous Southern California automotive service companies.

Competition Transmissions is one of the largest transmission repair shops in Southern California. With over 10 years at this location, the Santa Clarita Valley community has been good to us and we like to give back. We sponsor the Canyon High School Baseball team and each season, we sponsor a team in the Parks & Recreation little league program!

"Carlos and the team were more than accommodating. They fixed our Rodeo and a few days later it broke down. They towed it to the shop, found out it was not related to the transmission, but they fixed it anyway! They let me use a loaner car, too. Great guys!" Donna M
