Can someone please explain how the oil level in the 430 series gearbox seems to defy logic almost, and lose volume as it gets hotter?
There was obviously a percieved problem, when you look at the official rigmarole involved in checking it.
Make sure it is above the 'Safe' mark before you start, drive at least 3 miles, reverse a bit, make sure it's up to temperature on the guage, let it idle for a few minutes at certain revs. then dip it.
If the level is then correct, why can't that level, when cooled down, be marked on the dipstick for checking when cold?
I obviously haven't been letting the oil get hot enough when I check it, because after an hour or more of use, our gearbox starts to show a reluctance to change up, a bit worrying to my mechanically sympathetic ears!

Any thoughts out there?
