Worried about whining noise from trans
during cold weather only about 32 F outside, whining noise coming from somewhere (from trans it seems to be)
Usually after i've warmed up car it disappear, but yesterday it was to difficult to get it out.
Could it be just pilot bearing.. Or something more serious inside trans?
Low oil level?
Yesterday even in cruising in neutral it was... If i rembember right even with clutch pedal pressed down..... So pilot bearing should be cutted out in this situation

Oil would be the first thing to check.

Does it whine more when clutch is depressed, if so most likely TOB.
Is it a black tag or blue tag?
Usually the pilot bearing/bushing won't make any noise unless it's truly shot and from my experience it will be more of a grinding more than a whine and the only time the pilot bearing comes into play is when the clutch is depressed.

you salis "depressed clutch most likely TOB supposed to be Throw out bearing"
after you said "only time pilot bearing comes in play is when clutch is depressed"
you all right?
or did you mean something other?

If it does it in neutral and in gear, it could be the output shaft bearing.

can we please get some clarity here, my understanding, and it may be incorrect, is that a throw out bearing that needs to be replaced will make noise unless the clutch is being depressed. My understanding of a good test would be place the stick in neutral position, and do not depress the clutch. if the whining noise is present now it has the potential to be a throwout bearing. If you then deep press the clutch, push the clutch pedal in with your foot, disengaging the clutch plate, and the whining now stops. This would indicate a throw out bearing that needs replacement.
It is my understanding correct or am I off?

To me too. output shaft bearing or, or maybe bearings on synchros too, these should be parts that are rotating when in trans is cruising in neutral

Pilot bearing = it spins always when clutch is engaged (pedal depressed)
Thorow out bearing = it spinns only when clutch is disengaeged (pedal pressed to the floor)
If depressed pedal means release foot from pedal

Not sure how your clutch is engaged when you have depressed your pedal to the floor.
**edit, unless your hydraulic system is empty?
**edit 2, I think we have an english translation issue where maybe Christi@n is thinking that DEpress is the opposite of press.
in this instance its not. press/depress same thing. means pushing the pedal to teh floor.
cheers.
