I took my mechanic for a ride last night, and his first words were that the transmission input shaft bearing is whining and needs to be replaced. I was already a bit worried about the clutch, it seems to be engaging awfully high in the pedal throw, but there's no slipping. I could really do without the bearing being trashed though.
My questions are:
Is a transmission whine normal or is it indicative of a problem with the ZF6?
Does the ZF require a specialist to work on it or can we do the bearing ourselves?
I've been reading here about using the Castrol TWS for trans lube. My assumption is that the car has the original lube in the trans & diff, both of which I intended to change ASAP. Is it possible that changing the lube will quiet the noise down? What is the trans fluid capacity?
How about the clutch, I assume the high engagement isn't normal. Any recommendations on a bulletproof replacement?
TIA

A few years back I needed A tranny so I bought A reman blue tag from A dealer for I think $1100.I installed it and the first thing I noticed was A whine
from the input shaft bearing,I ended up returning it to the dealer.A couple of months later I get A call from the same dealer saying that they are selling it to A scrap guy and if I wanted to buy it from him,so I agreed to purchase it
for $250.00
I bring to the shop knowing that this transmission made noise I disassemble
it and found that cluster gears where burnt/dark as if it overheated and the other thing I didn't like about it were the gears and how the meshed.
So I changed out the cluster gears and different transmission housings
same bearings though.
So if you take out the transmission check out the gears and the cluster gears.
