We have a 1998 Cat 140H 2Zk. We have lost all gears over 3rd in both forward and reverse. We have ohmed all the shift coils and all are around 31. Anyone have any idea as to what else we should look for? Also changed the filter, does seem to have some metallic residue in the filter. Local dealer had three solenoids in stock and we are going to swap them out and see if we can solve it this way.
Cat finally came and it turned out to be the shifter.
Cool that that's all it was.
