Thanks for chastising me on this one. Getting a little cranky are we? =
I know that the owners manual specifies motor oil, I didn't choose to =
have it filled with 90 weight. What I wanted to know was if the use of =
the gear oil is causing my problem. I intend to drain the gearbox and =
overdrive, and refill with motor oil. I have one vote for 20W50, and =
one for 30 weight. What do you recommend? Do I need to flush out the =
box (if so, what should I use?), or is simply draining and refilling =
going to be O.K. =20
I also know what a dipstick is for, and in general how they work. =
Specifically how low is the tranny when the oil drops to the low mark? =
A pint? A quart? No marks that I have seen give me a clue, and seeing =
that it's already a pain in the ass to get oil into the transmission (as =
opposed to in the interior of the car, I would prefer to have some idea =
of how much oil to put in so that I don't have to keep pulling the hose =
out to check the level during the filling operation.

Chris....if the factory had felt it was OK to run the gearbox low on =
oil,
they'd probably have fitted a longer dipstick. Also, if they hadn't =
wanted
you to use engine oil, they'd have said so.
I think you just proved why it's so important to read the owner's manual
and do what it tells you!

It seems that the gears in the tranny have a ceramic like coating on =
the
taper that the synchro ring rides on. The bond between the coating and =
the
2nd gear failed, and the coating fell of, rendering the synchro useless. =
This occured very suddenly, one gearchange was fine, the next was
accomapnied by a crunch of gears, all of which resulted in the re-build,
after which everything seemed fine for several months.

I
noted that the 3rd gear synchro seems to be acting up. It was fine when
the car was put into storage. All new synchros were fitted during the
rebuild. =20

mark - I don't know how much down this mark signifies. The mechanic who

in
all trannies, and this is what he filled my box with. Also, when I =

the car, the temperature was quite a bit lower than in the summer when =

How
about the low oil level? Anyone have a feel for how low the =

is if the oil drops below the low mark on the dipstick?
