I'm sure you don't have a linkage issue. When you pull the shift selector out of park you go to reverse. Then to neutral, drive 1, drive 2 and low. If all the other positions work normally the linkage is fine.
The fluid could be fine looking and still have an internal problem. A broken sprag clutch could cause your problem. These can break without warning and no slipping. Bad looking fluid is caused from slipping clutches which overheats the fluid. The burnt clutch facing also discolors the fluid.
