If there are no faults in memory then its probably the range switch. It can be dismantled to verify. It sits on top of the box. Undo shift lever (10mm spanner) Remove switch (30TX) Leave loom. Remove cover (10TX) press out wiper and inspect contacts if OK clean out grease from surfaces, polish and smear light grease on. reasemble. adjust in N there should be continuity on the exposed terminals.
