2008 RRS l320 TDV8, Transmission fault message appeared yesterday, drives fine in auto, however
when you select Sport/manual position it does not work & still shows D on the dash.
A couple of times I have travelled about ten miles in Auto mode, stopped, turn engine off, then restarted
and Sport mode worked ok. Today have done the same, but not working. appreciate any tips/ solutions regarding
this.

Have you had the Gearbox Oil changed at all ?

Hi is it regularly used or once in a while? i had transmission faults and other various ones it was down to the battery being low.

Read the fault codes

Hi, thanks for reply's, Gearbox oil has been changed, used every day, about 600-700 miles per week, New Yuasa 100AH
battery fitted 5 months ago, rear stop/ taillight bulbs changed, have been told to change brake light switch as often
causes silly faults? Have ordered Genuine switch to try!
