help: auto tranny doesn't upshift when cold...

[Son Nguyen <snguyen@hydra.acs.uci.edu>]

Hi,

Just a couple of days ago, my '90 90 automatic tranny
doesn't seem to want to upshift when cold.  It would
stay in first and/or second a longggg time, even
if the revs are up to 4000rpm.  It takes about
a minute or two then everything would be fine again.

So on Saturday, I took it to a shop and had the tranny
fluid replaced.  It's still doing it.

Pls help,
