GS 2 8 0 9 3 = INCORRECT TRANSMISSION TYPE

Can't interpret what that may mean, maybe should ask a "real" expert, i.e. Rob Pickering or a Merces dealer that specialises in recent Unimogs.

And , does anybody know why it jumps out of gear when driving? you can be going along in 8th and all of a sudden it will go into neutral, then it will start doing it in all the gears, to get it home you have to put it into emergency mode.
Leaving it until it goes cold and it is fine until it gets hot again, obviously it seems temperature related, but all fluids are fine, no warning lights, no error codes.

You might have a speed sensor going out. There are 2 or 3 located in several places. I am guessing its the one on the side transmission. They are shaped like a shotgun shell and about the same size. they have 2 or 3 wires going to them and its a simple unplug, screw out and repeat procedure.
