trans diff or torque tube noise
02Z, at track day missed shift, before that there had been some noise.
Then, in 3rd-6th, lots of noise as throttle applied. None on decel or at steady speed. Can hear / feel through shifter.
Local trans guy said it was trans.
R & R with used trans, supposedly 22k miles.
Same noise on re-install. In my mind it can't be trans, chances of same sound / problem slim, but symptoms do no indicate diff or torque tube.
Thought?

I had a vehicle with similar problem. Under hard acceleration and about 4K RPM, the shifter would vibrate and make contact with the torque tube. Found out it was the TT bushings coming apart. That is where I would start.

Thanks, was it mid/high pitched hum? Did it happen in all gears?
