After a while of fruitless searching on the interwebz I come to you with a question. What transmissions work with a m60b30?

The ZF S5D-310/20, 5 speed with the V8 bell housing, only used on E34 530 cars in the US market. Same transmission as the E36 M3 5 speed, different bell housing.

The Getrag Type D (BMW internally calls it the S6S-420g), 6 speed with the V8 bellhousing, used on E34/E39 V8 6 speed cars including the E39 M5 (which is supposedly slightly stronger).

Thanks
