Power Shuttle failure - code 78? What\'s that?
Does anyone have their TN series service manual handy? I was out doing some work in deep mud/muck yesterday, and all of sudden the tractor decided it wasn't going anywhere. The Power Shuttle failure indicator showed a code 78, and the transmission disabled warning light stayed on - and we just weren't going anywhere anytime soon. I'm thinking that I was so deep in the muck that something got wet - and that's what I'm hoping happened. I checked all fluid levels, and looked around to see if I tore any wires loose, and everything looks fine.
After cycling through a few shut-downs and start-ups, the transmission controller reset itself and I was able to drive to dry land - but I sure would like to know what possibly went awry. Thanks in advance to anyone who has that code and any ideas handy!
