if you are condsidering a 200r ( god knows why) I would use a AOD. when built right they are durable an reliable. The 200r has nylon clutches and is prown to failure. The E4OD is a great tranny, and uses spring pressure as well as fluid to hold on OD so heat wont cause failure. You may also consider the 4r110w it is the next gen e4od, then comes the 5r... which is the torque shift. That is a 6 speed auto.
