auto uses a flexplate.... manual uses a flywheel
the 999 is a 3-spd auto (no overdrive). To my knowledge, lockup TCs are usually (or only?) found in overdrive trans like the AW-4, 700r4, 4L60E, etc.
You can check places like Quadratec, Summit Racing, Jegs, etc for TC options (if there are any "options" for the 999). TCs usually last darn near forever. why do you want (or think you need to) change out the TC?
