Clutch pilot bearing or something else?

Just listened again. I got it backwards - not the throwout bearing (sorry bout that). It whines the 1st 2 revs (clutch out, transmission spinning), quieter with the pedal pressed (trans. not turning). That indicates something in the trans. (bearing or gear?) when the input shaft is spinning.
Also, the pilot bearing and tranny shaft would not be spinning relative to each other with the clutch pedal released (up, not pressed) so I would say the pilot bearing would not be the cause. These are usually just a bronze sleeve anyway (no noise).

So what do you think? Maybe the output shaft bearing, i know i had to replace the rear tranny seal as it had been leaking for what looks like quite a while based on the amount of fluid that came out of the tranny when i drained it (about a quart and a half came out) so maybe the output shaft bearing wasnt being properly lubricated leading it to start wearing down? Just trying to get a list of things together for the mechanic to take a look at.

Depending on how low on oil and for how many miles the damage could be very extensive or not too bad. From what I heard on your vid, the input shaft was turning (and whining) when you engaged the clutch so definitely some worn parts there. Output shaft, who knows? That was not turning while you're sitting there.

I don't want to mislead you, I'm not a trans. expert and it would take an expert to give you a better idea of the possible extent of the damage. To really know, the trans. needs to be opened up and inspected by a pro.

Good luck with your repairs.
