Hello guys, I have a 89 toyota supra 5-speed. I have a problem with the transmission. Or related. Everything works fine. Shifting from gears 1-5 and the reverse works fine. The problem is, is that when I hit any higher than 2900 rpm, the transmission and the car itself vibrates. I just put in a new flywheel, and a Spec Stage 3+ kit. I assumed it might be the driveshaft. So I attempted to disengage the clutch by holding the pedal down. And by accelerating the gas pedal. And it didn't change at all. Anything above 3k rpm it would vibrate. I am stumped and lost. I tried swapping another transmission. And the problem still persist. I duno if it can be both transmission be bad or something else.

The motor mount is new. However. The tranny mount is used. I decided to swap with another transmission that used the old tranny mount. My old transmission never reported this issue before. Until I swap onto this new one.
