Yes it is a comprise to get a smooth operation, though when they are modded with a Transgo kit, they are not too bad, as long as the shift accumulator springs are not increased. They don’t do any thing for the line pressure.
The line pressure is a continuous flow of oil through the valve body, and mainshaft. It leaks oil through all the clutches and valve body drains. Instead of turning pressure on to a servo to move it, the drain is turned off, to allow the pressure to build up to move it. There is really no problem with the line pressure flow. As I have said before, that is solely a TCU control problem, made worse by the high final drive ratio.
