Notjustair... I am buy no JD mechanic, worked on dozers and other brand tractors all my 73 years. To me by it doing it when started to me it may be a hydraulic or mechanical problem rather than electrical. That thought is also reinforced by it not giving you a error code. You may have (1) a weak supply pump (2) clogged strainer (3 ) sucking air some where. The fact that it started in the higher gears then has worked its way down also indicates weak or low hydraulic pressure to close the clutch packs. Now JD seller can probably come on here and help you better but that was just my first thoughts.

Today's Featured Article - Listening to Your Tractor - by Curtis Von Fange. Years ago there was a TV show about a talking car. Unless you are from another planet, physically or otherwise, I don’t think our internal combustion buddies will talk and tell us their problems. But, on the other hand, there is a secret language that our mechanical companions readily do speak. It is an interesting form of communication that involves all the senses of the listener. In this series we are going to investigate and learn the basic rudimentary skills of understanding this lingo. ... [Read Article]
