Sigh, I buggered up the outer seal lands on the servo piston prying it out of the case (expensive lesson, CK billet servo), however the larger seal (closest to the band side) had a 3/4" tear. Not sure if I did that or it was already torn. My question is would that tear have resulted in the 2-3 bind that suddenly appeared? I have a new servo on the way, along with CK's book.
Here's how the problem progressed.
~1500 miles since install everything is well, firm, positive shifts with negligible bind on 2-3 at very light throttle. WOT had crisp shifts
One day after track outting I noticed the 2-3 bind at light throttle, went away as trans gets up to temp (start to notice 15-20* increase in coolant temps, I have in rad cooler then external)
Drop pan and retorque valvebody, now 2-3 bind doesn't go away when trans up to temp. Feel drag after 2-3 shift, have to let off throttle for drag to go away.
Lose 2nd gear, shifts 1 to 3, pull servo.
