slushbox woes

[Mike Mulholland <meyeke@netinc.ca>]

during our recent cold snap the dil's 5ks has developed an annoying problem
with the auto tranny. it shifts smoothly at all times but when cold will not
shift from 2 to 3 until driven a few kilometers. i imagine this means..until
the tranny has warmed up. once the magic temp is reached, it will smoothly
shift into 3rd, and downshift smoothly when slowing. further acceleration
results in a smooth shift from 2-3 from then on. once warm, there is never
any hesitation or delay or lack of smoothness when shifting in all gears.
any ideas? i have changed the tranny fluid twice, so it's nice and clean. i
also changed the filter and cleaned the pan.
