Thankfully, I was referred to your shop where I feel like I was treated far better than the shop I use here at home in Roseville. For That, I salute you and your crew for a job well done.

I wanted to thank you again for the work you did on our van's transmission. It has proven as reliable as your reputation for good auto transmission work and I assure you it has paid for itself at least ten times over.
