I am in need of your expertise again as I have an issue I have never
run across before. The car is a bone stock 1995 mustang GT with 5
speed trans, ~85k on the clock. When I start the car with clutch pedal
depressed, it starts instantly and sounds great. Every once in a
while, I get this horrible howling sound which at first I thought was
the serpentine belt so I replaced belt, tensioner and idler pulley.
Now I notice that if I let off the clutch the howling goes away and if
I depress the clutch the noise usually comes back. This howling is
only when the car has sat for a few hours, outside ambient temp is less
than 70 degrees and usually lasts 2-10 seconds. I have no drivability
issues and the howling is definitely intermittent. To me this sounds
like a clutch issue so I am thinking it's possibly the throwout
bearing? Are those prone to issues on this model? Am I way off
actually other than the clutch pedal connection, I've run into a few of the
94-95 that "howl" when first started usually it traces back to the fan. but
in your case I'd probably check the pilot bushing and/or level of gear lube
in the trans. Sometimes the synchros can get a little dry and howl/whine
until the lube spreads out. Especially if the car has hit a few deep water
puddles, sometimes the self sealing vents don't. The pilot bushings
(actually a bearing on your car) are know for running a little dry. they are
a pain to lubricate. time to drop the tranny, any rear main seal issues
while your at it, or O2 sensors?
Thanks for the info guys. I haven't gotten to the trans fluid yet as I
am waiting on a factory service manual. Maybe you can tell me what I
need to know? What type of lube does the 5 speed use, 90 weight? How
much does it hold? Does it have the drainbolt and checkbolt
