Default t-maxx shift problems

my t-maxx 2.5 will not shift into 2nd, even when i let it rev to its limit, it doesnt shift. i have adjusted the screw for the shift point, and it does nothing! the thing was, i was driving it a few days ago, and the shifter worked! am i going to have to take the transmission out, and fiddle around with the gears? i have not overtightened or overloosened the screw.

thanks!

i just ripped the tranny apart, for the first time, and this isnt as complex as i thought it would be. i see the gears, the smaller one is supposed to move freely, right? i checked the spring on the 2nd gear , and it looks fine. what would happen if i removed the screw/spring completely? would it cause both gears to engage, and shred eachother? i havnt tried tuning it to its best, but i rev it MUCH higher than it usually took to shift, but it doesnt. i am puzzled.

if there is anyone who is experienced with these trannsmisions, i may trade this stock one , with another working stock one, for a deal! i am tired of this!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

while you have it apart clean the oneway bearing in there and then replace the 2 speed clutch there like $18 and they come pre set. if that dosent do it you are not pulling the high rpm's needed to shift it!
