my d7 17a with a cable blade has the forward and reverse lever frozen in forward position-the gearshift is frozen also-this has happened two or thee time before and for some reason just started working fine-I have removed the floorboards and see no reason for the problem-any help on what to do next appreciated.
Sounds like the transmission interlock is not adjusted correctly on the linkages. Adjust them to the Cat specs and see what happens. Ken
