I recently went to AAMCO in Marietta, GA with a Trailblazer that was leaking transmission fluid. The tech took a look at it for about 5 minutes and gave me a quote of $629 for the repair. I told him I might return, then went to a locally owned shop named Certified Transmissions. They fixed it for $369. My advice for anyone is to check around a few places before authorizing any work. It could save you a bundle.
