Rolling Stop 4l60e Slip
 

I'm having trouble with the tranny in my 99 Jimmy 4x4. For example, when I roll through a stop the tranny will slip up about 500 rpm for about 2 seconds. If I come to a complete stop and wait about a second or so, then accelerate then it's fine. It seems to be worse when it's cold. Fluid is clean and up to level.

Thanks
