Does anyone know if its possible to fit a later MB lockup torque convertor to work with a 722.xxx series transmission?(or modify any other lockup convertor to work) If so - whats involved in the conversion? The application is for a MB diesel/tranny combo in a non-MB vehicle - I'm interested in the lockup convertor for compression braking more than for highway use.

Not possible due to fluid flow & mechanical design of older transmissions.

can you be more specific about exactly what wouldn't work? I'd expect fluid flow to be as per a standard convertor when past 'stall' speed, and the 722.xxx series transmissions have a rear pump anyway, so seals/lubrication/fluid flow aren't an issue. Automatic control isn't a factor either - as I'm more interested in synching it with the compression brake for my application, it can be as simple as a contact switch in the lever that controls airflow to the jake. (its a 240D, BTW, and has already had a custom turbocharger added)
Perhaps you'd care to describe exactly how the MB lockup convertor is different to the standard convertor - I understood that while they potentially had different dimensions, the lockup convertor was essentially teh same unit with an electrically actuated clutch inside...

TIA

It has an elecrically and hydraulic actuated clutch. I don't think you would be able to make it work either.
