Shift kits generally up line pressure, it reduces friction of the clutches, by reducing clutch slip. That is why you get the hard shift. You get longer clutch life but depending on the transmission you can get broken hard parts.
It effectively takes the overlap out of shift so you lose the smooth soft shifts.
It is generally installed in the valve body.
Automatic transmissions have clutch packs and that is generally the first thing to wear out.
A torque converter is fluid coupler. It allows the engine to spin almost independently of the transmission. It is responsible for pressurizing automatic transmission fluid, the pressure supplies the force necessary to the clutches and bands. So as you apply gas the torque converter spins and the pressure comes up moving the vehicle.
On newer vehicles you maybe able to get away with a tune to change it, but stuff like the 4L80E and 4l60E can still have it installed in the valve body.
