Have a 2013 Buick Lacrosse that developed transmission problems. After a detailed diagnostic test Cory explained every code in detail and what it would take to fix. The transmission had to be rebuilt. After tear down he called me with a firm quote giving me the price and the down time. I received the car back two days sooner than expected and the cost was to the penny. After a long search I think I have found a shop that does quality work and one that can be trusted.
