Transmission slipping when cold, then stops
 

I have a 1996 JGC 4.0L with AT.

The other morning the transmission started slipping between 2nd to 3rd
gear. It stopped after driving a few minutes which I figured was due
to it warming up. It won't due it for the rest of the day, only
mornings after sitting throuogh the night.

Any idea what's causing it? Is the trans doomed???

Please post response to group. Thanks
