Replace TCM in Altima

Do NOT use this shop. I had my Altima in for a shifting issue. After $1200 ($500 in Labor) I got it back with MORE ISSUES. I picked my car up and it not only had the Check Engine Light on - which was NEW, but it was drivable when I went back about a week later after the work to mention a newly developed problem. After less than a 5 mins drive Dominic comes back telling me I need a whole new transmission. I ask how they originally got to the diagnosis - Dominic very soon was telling me to "Take him to court" - I hadn't even asked for ANY refund yet! All I wanted was a correct diagnosis. Very quick and expensive, thoughtless work. They are a "Parts Changer" not a mechanic.
