I would highly recommend a 2002-2008 trans. According to ATSG, starting with some 4L60E in 2001 and all in 2002, the Sun Shell, Thrust bearing and Reaction Carrier Shaft were updated/strengthened to handle the increase torque of LS2 engines. This seems to have solved most of the problems of pre-2001 transmissions destroying their sun shells.
(2009 and later transmissions are incompatible with earlier PCMs.)

I'm no transmission expert, just my opinion.
