My '83 Avant sometimes sticks in 1st gear when cold. It has been doing
this intermittently for two years now. About 3 years ago, I had to
get a recon dif as I suddenly lost huge amounts of ATF fluid and I was
told that the dif had a very chewed-up bearing and shaft. The
mechanic told me that the auto box appeared ok as the fluid was clean
(this was probably because the only way I could drive the car to the
work shop was to put in a couple of pints of new ATF).
I have noticed that this intermittent sticking in 1st gear usually gets
much worse the day after a long trip. This points to hardened (and
less effective) seals. On rare occasions, under hard acceleration
when warm, the gearbox feels as if it is leaping backwards and
forwards between 1st and second. Also, sometimes the change between
1st and 2nd feels as if something is slipping and I have to wait until
3rd comes along before the soggy feeling goes away.

Level for me is OK. However, fluid looks dirty, not black, but
definitely dirty.

I thought cleaning the screen was OK. Do I need to replace it?
I asked the list about this before - one suggestion I got was to clean
the governor. The day before I was due to do this, the problem went
away (but only for 6 months or so - typical).

I'm not Stephen, but I would be very interested in more information on this.
