trying to up my trans knowledge and figure out what effect different spring rates have on 2nd gear servo operation.
There a 3 holes in the front servo bore.
im assuming the oil comes in through the top hole and pushes down on the top of the piston pushing against spring tension causing the center pin to push down on the band strut and causing the band to tighten.
question is where does the oil come from? where does it go?
from there what causes the servo to release tension and what are the 2 bottom holes for?
I’m assuming a stiffer spring would cause a reduction in pressure on the servo center pin…
or does a spring that has to much tension make the servo release the band faster causing a potential flare 2-3 shift?
