So me and my buddy was driving the supra today and it was running/shifting great. Then after about 50 miles the transmission just stopped working. We did get on it at times. We were running 15lbs boost, and probably pushing 325hp. The car still runs fine and everything, but when you put it into Drive, 2nd, or Low, it doesnt move when you give it gas. It acts like its in neutral. We have changed fluid and filter in tranny also. Anyone had this problem before ? Thanks
