Actually, since deep diving into the MTX75, and finding that the IB6 is the 6 speed version of the IB5 with the Zetec bolt pattern, it appears that the MMT6 is the 6 speed version of the MTX75, although I have yet to see whether it has the Duratec bolt pattern - but given they were available when the Duratecs were still running (prior to Ecoboost) it is likely. The dude from SiCo developments in the UK did attempt a partial MMT6 swap in the past, but only got as far as doing a test fit before moving onto projects for newer models. It does appear that the MMT6 will fit. Those transmissions could be found in some Mondeo's in Australia, and possibly some higher spec non XR5T Focii. As they are in newer models, however, they'll still be a bit expensive at the moment.

Here is a thread on the subject - there's no detail, but there is a small pic. All the same custom work I'm currently doing for the MTX75 would have to be done for the MMT6.
