I just bought a g3wd gradall excavator and now it occasionally doesn't shift like it should, more into reverse....any input??
G3WD used a funk transmission and torque with electric shift. These machines did have some electrial problems first thing check the connectors for the electrics then ALL the grounds.
Holy electrical connections!!! I just unplugged and plugged in some things and it all seems to be working now....thanks for the guidence
get some good dielectric grease and go back over those connectors too
