Gen6 724 not selecting speed range

Problem: Gen6 724
'The neutral selector of the speed range is faulty'
'The selected travel speed range is not recognised'
'The range switch is in the neutral position or the neutral position is engaged'

Was onto the tech and he directed me to the red lever to select 1-N-2 which held it in 2nd all week but dropped into Neutral again this morning, anyone know the cause or fix? (Awaiting a service) Cheers

Was a potentiometer failed on mine,up beside the diesel tank,it couldn’t tell what range it was in so defaulted to neutral.
