I have a 9770 that the dealer just swapped 4WD from 07 9760 last week, and now when 4WD is engaged in high and you either turn right or get on the hydro a little it automaticaly shifts to low speed 4WD and then sends an error code( cc#204 left motor high refer to diagnostics and repair) I've called the dealer but have got no reply as to why it is doing this, any suggestions maybe a hose in the wrong spot? they say it has been calibrated also. TIA Azcutter

Re: 9770 4WD

sounds like you have a pinched wire. if your high and low work correctly part of the time, that means that the hoses are good
