Can't say what I don't know.
Fluid was 2 quarts over full and looked fresh ?
It's a 4WD but no idea of the trans model. 130,000 miles. So far on other forums advise to disconnect battery cables and clean all connections, short them together to reset computer, check both shaft speed sensors.
I am 1500 miles away until the 25th when I go to Fl and might get to see this rig. Have never been inside an auto tranny. Will pursue needed info,Thanks
