Ok I have read all the shift problem threads and cant seem to find one like mine. I just got this fourwheeler a couple weeks ago and guy told me it need the shift sensor that the shifting messed up ever now and then. Well just the last couple days every time I ride it down the rd and get up to 4 or 5th gear the gear will flash then go blank and wont down shift until i turn it off and back on. But it does fine going slow putting around the yard. I put a new angle sensor on it today and it didnt fix it. And the speedometer just reads 0 the whole time. Code that blinks i think is one long and one short... So whats my problem? any ideas?
