G50 Gearbox Casting Shape

[bodmin]

I've often wondered what the reason for the three lugged casting shape is on a G50 gearbox.

Can anyone explain what it is and why it is there?

That's very interesting, thanks. Although hard to believe that the flange was cast in anticipation of 996 oil pump being able to fit it 10 years after the event!

I think most 911 gearboxes 901, 915 and G50 had some casting provisions for an oil pump in the gearbox..some gearboxes actually had an oil pump too. Helpful for sustained high speed driving on the Autobahn.

Aren't G50's just the "cats meow"? So glad I have one.

That all depends on what you are looking for in a transaxle.....

Anyone got a picture of the pump which would attach to this flange?

What else do you need? They handle over a 1000hp, shift great, and 5 speeds.

Not everyone needs or wants a transaxle that handles 1000 HP. There are cost, mass, and spinning mass penalties some don't want to pay.
