I went for a tour this morning and blew a heater hose the hard one to replace under the power steering pump after fixing it I continued on and my supra started to shift hard by thr time I got it home I had to shut off the car to get it gear the clutch pedal is on the floor it made a few swishing sounds and thats it....My question is this the clutch pressure plate or a slave cylinder screwing up ....Thanks for looking Barry
