You have a problem with low pressure at cold temps.  This is usually caused
by a clogged screen, bad pump, or internal leakage in the transmission.  Try
checking the screen first.  If it is clogged, that is an indication that the
clutches are shot.  Even if replacing the screen fixes the problem for now,
you will need to overhaul the Trans in the near future.  Most of the auto
Trans parts are available at a local transmission shop.  When overhauling
the Trans, I recommend replacing the torque converter as all that crap in
the screen is stuck in there also.
