Now the car is out of production there probably are no new ones available any longer. A ZF rebuild (assuming it's a 6sp) will normally have all the major working parts replaced with just the case, shafts and gearsets from the original build unless they were damaged or badly worn.

Certainly my rebuild had everything such as valves, gaskets, clutches, hydraulic controls, bearings, torque converter, pumps, filters and fluids done. Even the additionally replaced mechatronics unit was a ZF refurb one (direct from Germany) and had to be 'taught' it was on an X5. I had to have a second rebuilt unit as the first attempt had a problem on the 1st - 3rd gearset (damaged) which was missed first time around so the tranny was completely changed out for a second rebuilt unit and is now absolutely fine.

The only advice I got was to take it easy for 1,000 miles, not to use 'Sport' and avoid high rpm (above 3,500 rpm as mine is a diesel) and kickdown if possible. It goes back at 6,000miles/6 months for a follow up service and fluid change.
