I just had a rear main seal replaced on my engine at Autotron in Pleasanton, Ca. It was the best service I've ever had at a shop and that includes toyota dealers and private mechanics. They called me all the time to ask questions to get to the root of various problems and they kept me informed of what was happening.

They were very knowledgable, friendly and specialize in Toyota, Nissan, Mazda and Mitsubishi. I highly recommend this shop.
