Auto trans query

["Stephen Bigelow" <sbigelow@sprint.ca>]

After a four and a half hour thrash at 80-85 mph (4000 rpm), I stuck Audrey
in reverse to back into my parking space and goosed the throttle.

She barely moved. Oh dear.
Managed to idle her back into place, and let her rest.

She had a differential replacement last week, and of course the trans was
corrupted with nasty gear oil, and who knows, bits of seals?

I've swapped out three or four quarts of trans fluid to ease the gear oil
pollution.

Anyone have any ideas what's going on? It was about 4C out, although I'm not
discounting heat.

Stuck valve? Messed up first/reverse clutch?
