Empire Transmission was built on a simple promise: treat every customer's vehicle like it was our own. We specialize in transmissions, so when you bring your car in, you talk to the people actually doing the work — no middleman, no upsells, no guesswork.
Gustavo built this business on his own and has kept the doors open for 15 years — backed by over 25 years of hands-on experience. Self-taught, self-sufficient, and driven by the belief that hard work and honest service speak louder than anything else.
