AODE guys can swap to M-V if the system is completely drained and refilled. But the MV is a synthetic blend and helps with shudder control with regard to the AODE - I dont see the need for it in an AOD.
A trans cooler is a better way to extend the life of the fluid.
Curt's number sounds nice to me. The pan drop will probably lose 3-5 quarts (the converter has half the fluid in the system).
