I Got It!!!!

[Shadow350Z]

actually no
cuz i adjusted the servo horn on my shifter to make 1st gear into center position of the 3rd channel 3P function
then adjusted the travel on the 3rd servo 3P function(FN3+) to 180(which is max) to shift to 2nd gear

you jus have to hold the transmitter a lil bit different to use the second gear right... if not you might let go of 3rd channel button and mess up the tranny gears or even worst.... DROP the spektrum DX3
