Well i bought a used tranny out of a 07 wrecked truck with 20k miles on it for $650...i've got it install and everything is hooked up...Tomorrow i will top of the fluids and take it for a test ride...(got my fingers crossed)..I sold the cut outs last yr so i will have to do some exhaust work b4 its completly finised...As far as the original tranny issue take a look at the pic of what broke ...I have no idea what could have caused the servo to put so much pressure that it actualy cracked the casting....Well take a look at the pic and tell me what you think...BTW i put atleast 20k miles on the tranny with the servo mod and im sure there was nothing out of the ordinary done to the tune..
