as the title indicates, i have a problem which started tonight - truck ran pretty well for the past 2K or so that i've had it - 182K on the clock. stopped for groceries, came out and truck will not shift. moves though, 3K rpms = 20 mph or so ...

need help ! fluid could be changed, but is up to level when warm. drove in 4wd this past sunday for a few minutes and that worked good too ...

any suggestions would be great. thanks.

 

did yo have it in 4x4 on dry pavement?

 

no in 2H

 

update - this morning it works ! i am having a fluid and filter change today. hopefully that will cure what ails it for some time.

 

You could have a shift solenoid thats starting to go bad.
