5.9MAG/trans into 65 Valiant

Just about all of the threads i seem to have dug up that mention a Magnum swap, dont seem to give any info on if the trans out of the same donor vehicle can be used. lots of info on mating the Mag upto the 904 that currently resides in the car. If there is a thread out there, then please, by all means, direct me towards it.I am buying a 2000 Durango 5.9 4X4 for $1000, Mainly buying for the motor/harnesses and the trans core ( it has no reverse), and parting out the rest. My car needs a trans to be rebulit one way or the other so i figure if i can, i'll rebuild the trans that goes with the motor and have O.D.Will the tranny from this 2000 Durango work in a swap into my Valiant?
