Great Auto Repair Shop!! Mechanic Frank was the best. He was honest, straight forward, gave reasonable estimates for costs, time, before each repair. I was charged $200 for a check engine light code check at another auto shop and had to wait overnight (Bauer's Auto Repair in Berkeley) when it cost me only $55 at Santa Rosa Transmissions to do the exact same thing in 1.5 hrs. They replaced my transmission at a good price and now it drives really well. I havent met everyone there but Frank was great. The operator lady was not very nice though... but she wasnt the mechanic so I dont give a rats ass. Recommended to all those who want great honest service at a reasonable cost.
