so i just got my diff and trans fluid flush with red line fluids.. still makes the sounds.. putted the car back on the lift and and started the car and did 1st - 3rd 2500-3500k slow shifts and the sound seems to be coming from between the driveshaft and the transmission... hmm no clue whats wrong at this point.. when they were under the car they said it makes the sound when clutch engages when the shaft stops and go.. also got the solid z1 motor mounts installed and dont no if that have anything to do with it either...
