Yeah the early TH700 only had electronic on or off for lock up.
A PWM soft lockup came later for GM.
If you can't really feel it shift then there is some electronic or hydraulic trickery going on.
By all accounts I have been able to find soft grocery getter shifts ruin transmissions faster as it wears clutches faster than hard shifts.
