I have a TKO, but its the older version before there was a 500/600. It was either 3550 or TKO...what is the difference
between the older TKO and the newer 500/600 ones? I bought mine back around 03 and cant remember spit about it. lol
There is more to it but the short and sweet is :

3550: 350 ft/lbs torque rating, 10 spline input shaft, 28 spline output shaft.
TKO: 375 ft/lbs torque rating, 26 spline input shaft, 31 spline output shaft.
TKO-500 500 ft/lbs torque rating,
TKO-600 500-600 ft/lbs torque and has a different gear ratio than the 500

other than the splines/ratios, the 500/600 added provisions for multiple shifter locations. thats really about it other than maybe some production-line upgrades/tweaks/cost cutting.

So just called apt to get an update, apparently tremec hasnt shipped a tkx yet. not sure if because of covid or other production problems. was also told tko production is done so whatever is in stock at the dealers/wholesalers is it. were originally supposed to start shipping out last week or two of november. t56's seem to be unaffected though (dont know if they come out of the same plant).
