Hello
I have been finding it difficult to select 1st & 2nd gears for a wile but thought that was normal anyway I have not driven the patrol for 8weeks jumped into it yesterday to go for a spin and noticed I couldn't select 1st 2nd gears took it for a spin around the block to try to see what was wrong and there are no strange noises just cant select 1st and 2nd gears not sure if I can access the top of the gearbox without removing it or does anyone know of a simple fix. my patrol is a 2005 ddti and has had everything repaired 12months ago for a cape trip including new engine and clutch.

Hoping its not going to be te expensive to fix
