Dealer has requested NH Assist on a code 81. Says the tranny is fine, but cannot clear the code 81 from the computer, which prevents tranny from working.

Any ideas?

There was a previous discussion on this back in Feb. Not sure if you saw it - Do a search on code 81

You will most likely have a faulty Charge Pressure Switch (part#82031395). It is located on the left hand side of the tractor and is accessible fairly easily. Your dealer should be able to supply you with one and giv eyou additional info. Good Luck......tractorman
