What\'s this bit of tin?

Underneath the gearbox there is a big old piece of tin. It looks like a undertray to provide some protection for the transmission, or to catch oil

Does it serve any particular purpose does anyone know?

if not, then I\'m going to get shut of it. It doesn\'t look strong enough to provide any bracing or strength - it is just a big ripped piece of steel. Runs from the bell housing back under the transmission.
Also, the scramer pipe (there\'s another noise problem for me to solve) has managed to burn a chunk of it off anyway

If memory serves me correctly with the undertray fitted it completes a tunnel type thing, so air going past the engine and down the tunnel has to go past the gearbox before going everywhere else.

Ah, I wonder if is using that airflow to help keep the gearbox cool, as the gearbox has ribs on it - a bit like the ribs or fins you see on an air cooled engine.
Thanks.

It is still heavy though - if it is useful I\'ll make up something in alloy sheet to do a similar job with les weight.
