I am just looking for an explanation on this. Its a 98 yukon with freshly rebuild auto trans. When I'm cruising over sixty it starts to slip out of OD up to 2000rpm. If I gas it a lil the darn thing drops back down to about 1400rpm where it should be. There is plenty of fluid in her. (Maybe to much?) It does not make any sense to me! You would think that it would slip worse under load...What am I missing here.
Anybody?
