Art, the 2nd gear servo should be blocked .
The 2nd gear servo accumulator which is the small one between the two servos should be blocked between the case and the piston to its top most position.
Also make sure the 2nd servo top cover fits the pushrod closely . ...If its worn ,fluid loss will cause a slow 3rd shift, as 3rd clutch apply pressure also helps release the 2nd band ....A stiffer spring in the top of the 2nd servo might help ,but it sounds like you might have a fluid loss problem. ..
Direct clutch clearance should not be more than .060"
The 2nd band adjustment can have a slight effect in the 3rd shift timing.
I'd set the band @ 1 3/4 to 2 turns backed off from 72 lb.in.
