Cuts out at WOT?

Hmm... I examined everything in the tranny, i noticed the idlers where really worn down, and that was about it. I looked at and hand-tested the peice that shifts gears (has those 2 nubs sticking out of each side), seemed function properly, in either gear. When i get home, I'm going to look and see how compressed the spring is on the shifting servo when in second gear, perhaps its not entirelly engaged... seems odd tho...
