well, the DualAction started with the belt drive Kenmores....maybe a marketing gimmick....but it was their best alternative to getting a bigger load in a machine, waaaaay before the larger capacities came about...
one thing about Kenmores was their agitators, or for most of them anyway, was the vanes were at the bottom, where all the cleaning happened, and you weren't getting use of the full capacity of these machines in favor of turnover...the dual action at the slower longer stroke was a great help....
I have never had isses with either drive method of using a DualAction....some others have had clothes torn, for one reason or another...
with your KA, is that the small or large base?......the larger base, even at medium water level, without the corkscrew, at medium or high speed, can turn that water into a tidal wave.....I put this larger base in all of my DD, at high speed, and have never had an issues with clothing or mechanics of the machine.....
