don't think it is shifting at the right time. 1-2 seems ok, good and firm, but seems to be a little late unless I manually shift from 1-2 then it's instant. Shortly after going into 2nd while either in D or shifting from 2 into D it seems to shift quickly to 3rd
Is this at part throttle or WOT? this might be too simple but would a weaker spring on the 1-2 shift valve let it move (shift) earlier and a stouter spring on the 2-3 shift valve so it would shift later. No expertise here just thinking out loud
