Levers are common to fail, but as you lost both directions, check the transmission fuse in the dash.

check you have oil pressure in case the pump has failed, do the main hydraulics work? damper coupling between gearbox and engine fail sometimes.

When the battery transmission fuse (40A) is disconnected and exchanged for the same, the machine works, but once hot, the problem returns, the working hydraulics work. I don't have a user guide for the machine, so I can't identify the fuse. Do you have a schematic or manual of the machine? Thanks

The big 40amp fuse under the cab does not supply just the transmission, if its blowing or bad connection you need to fix it but otherwise it will not have any effect on the transmission.

if your loosing drive only when the transmission is hot then the transmission clutch packs are simply worn out or down on pressure due to leaking seals and transmission pump worn.

I dont have any info no, see if there is a manual behind the seat, that will tell you want fuses are what.
