my friend has a 2003 honda foreman 450es that will shift from 2nd all the way up to 5th and back down to 2nd again but won't shift from 2nd down to 1st. the electronics keep trying to make it shift and the shaft with the manual lever on it looks like it shifts but will not go down into 1st. it looks like it rolls far enough to shift i don't know if something is cracked or broke under the front cover, as I've seen some people talk about gearshift plates or guide plates just looking for some ideas before tearing this thing apart.
