I got a 92 mack with 2070A trans. I have lost ALL gears, the pto still works was able to dump load at quarry after being loaded. No previous problems at all. I can push shifter into all gears WITHOUT clutch pedal being pushed down, and you can hear the gears slow down before shifter goes into gear. When I do let clutch out you can hear it engage and lug engine for split second. Absolutely no noise chatter or nothing. I backed up to pile to get loaded and that was it would not move. Thanks in advance
