Last December, my transmission started having problems and a friend referred us to Auto Dynamics. We took my car there, and they first tried to replace the valve body. When that didn't work, they recommended that the transmission be rebuilt. Since they were going to rebuild it, they didn't charge for the work they'd already put into it when replacing the valve body. Also, the price they quoted us for rebuilding the transmission included labor and taxes and when we picked it up, the price they quoted us was exactly how much we paid. (We all know how some shops try to tack on additional/hidden fees.)It's now been almost 7 months since they rebuilt the transmission and everything is working GREAT!
