John sold me a transmission with a year warranty and it broke and he told me I broke it so it wasn't under warranty..... What the hell is a warranty for exactly?? If it breaks it's fixed by the shop.. I had to haggle for a day just to get him to cover half the cost.. Beware a warranty at the mustang shop is not a warranty. Oh yea and he sold me a 5.0 engine that had the lowest compression that I've ever seen and almost didn't take it back. 40psi was the highest measurement I got on cylinder 2.if you want good mustang parts go else ware!
