Javi Trudeau, 06/25/2026

I had a very positive experiences with Tucson Transmission on three separate occasions. The office people and the mechanics were very friendly and knowledgeable and the turn a round time was reasonably quick. Even though I didn't have my transmission worked on, they did great with my alternator, water pump and tune-up. I recommend them highly.
