Audi B7 2.0 TDI PD BLB with Multitronic transmission, code GYJ.

Transmission is going to die soon so I want to explore if I can swap 5HP or 6HP tiptronic in its place.

Can someone make 2.0 TDI 16v engine get along with either Tiptronic transmissions?

What would be involved in this?

I'm willing to pay if necessary of course.
