Transmission shifts to early after rear end gear change.

Question I have that may help out the OP... Does adjusting the line pressure on the valve body affect the shift points? I just put a TF-2 kit in my 904 and I've had to adjust my throttle pressure cable (Lokar) wayy down to get it to not shift too late. When I got the VB back together I gave the line pressure screw about 3/4-1 turn in from where the spring seat was touching the plate (fully "out"). Y'know, just because I thought a little extra wouldn't hurt...?
