Hi,
I'm having the above issue and before that it will not drive in second gear, showing a F on the gear indicator screen. If you park the coach up and isolate it for an hour or 2 it will start but once hot will do it again. Here is a video of the service light and warning sound https://youtube.com/shorts/-6Cb7MhhXFQ
This is my first ultrashift and I'm a bit lost,there seems to be limited mechanics in my country who are experts. I'm thinking it must be some sort of sensor but how do I determine which one or do I replace the lot?
Eaton Ultrashift engine will not start in neutral when hot

Try unhooking the main battery, let it sit for a couple of minutes then restart it. Sometimes it's a sensor, sometimes automatic trucks hang themselves in gear, sometimes it's a bad harness, it could be anything. The last time I drove an Eaton, the F came up on the dash and it would hang itself in gear.
