Answers :

This is a hydraulic leak inside,the seals,or wear on the seal surface.When the transmission heats up,it expands just enough for fluid by pass.The transmission needs hydraulics to shift,and to shift properly.If you can shift the truck by hand and make it shift,then the valve body,or the governor would be the problem.But I bet it will not shift by hand will it?I have seen ,behind the front pump,where it bolts to the transmission,have a crack in the bolt thread and cause this problem also.But in this case,I believe the problem is in the seals,if all of them were not replaced when the drums were installed.Did you use recommended fluid?Check and make sure,if it takes the synthetic trans fluid,and you used dextron three,this could be the problem,the valve body will stick,every time.If you are able to shift the transmission by hand,and make it shift out all the gears,then this may be the problem.If you feel the valve body is still the problem,go to N A P A auto parts,and ask for Lube Guard,in the red bottle,and add this supplement to your transmission,this will correct the situation,if it is a stuck valve body.This additive treats the metal,not the fluid,and will stay in the transmission.
