The transmission has no effect on agitation or spin speeds. Speeds are in the motor RPM, not in the mechanicals of the transmission.
There are no electronics or circuit boards involved. The timer is mechanical.
Your Estate probably has a 1-speed motor and simulates gentler agitation by running the motor intermittently on the Gentle or Delicate cycle.
I can't find a tech sheet for the KA 560 but I did find a user guide. It doesn't state any agitation or spin speeds for the three cycles. The illustration of the timer doesn't show any wash times, just soil level references. There are wash time references in the written cycle descriptions.
Regular/Heavy
Normal (or Heavy) = 10 mins
Light (or Normal) = 6 mins
Permanent Press
Normal = 7 mins
Light = 4 mins
Knits/Delicate
Normal = 1 min agitation, 2 mins soak, 1 min agitation
The descriptions lead me to conjecture that, regards to having the larger agitator and a 2-speed motor, it runs the motor at low speed for all agitation. Possibly at high for spin on Regular/Heavy and at low for spin on Perm Press and Knits/Delicate ... or possibly stepped on Perm Press .... or maybe at high for all spins.
