Hi everyone, new to this. Spent days researching to make sure I don't double up.
I have a 2011 fg mk1 xr6 tray ute dedicated gas with the 6 speed. Just recently it has started to play up. It has my mechanic / transmission joint scratching their heads. Up until 100 car is perfect as can be. Go over 100 it goes from 6th back to 4th. If I put cruise on at 110 it is fine. Take it off and it drops back gears. Can manually select 6th. Mechanics have checked everything they can think of including changing lhs front bearing, abs sensors etc etc. Anyone have same issue.. thanks in advance. Rob
