ok so here is the problem
my transmission makes a nasty whine. happens when moving and stationary. in nutral with the clutch out the whine is there but as soon as the clutch is down the whine goes away. same deal when driving. what does this tell me?
i've broken it down to this:
-when in nutral and the clutch is up only the main shaft is spinning but no gears are engaged (obviously)
- when the clutch is down the main shaft stops and the clutch and throwout are still spinning meaning they are eliminated as the problem.
- so in my mind it would point towards a main shaft bearing
- here's the kicker. i JUST picked up the transmission from a tranny shop that just replaced all the bearings. i sent it in because it was making the noise before the tranny refresh.
- the shifting is smooth so syncros seem to be fine
- clutch is new, trow out is new, pilot is new,
in the vid clip
- don't mind the footage, focus on the sound
- you hear it at start up plus in the vid you will hear the whine pulsing which is me depressing and releasing the clutch not the whine just pulsing on its own, its a steady whine, louder under load
the phone is right over the shifter housing with no shift boot or rubber boot, i find the sound is loudest there.
help?
