Don't want to sound like an a$$ but Sun shell stripped means no shift at all. No planetary action from band grabbing in 2nd or 4th. The 3-4 clutches need to drive the Internal reaction carrier (front planet) and the sun shell cannot be driven at the same rate if the splines are stripped and would not drive the low planet at the same rate (since 3rd would be a direct 1:1). The band would still apply in 2nd and 4th but there would never be a progression in gear change. He is getting a shift but late. He said 2nd and 3rd but late -3500rpm or so.
