I just picked up a 2009 lancer gts from the auction and it's throwing codes p1773, p0776, p0868. I know they all seem to relate to the valve body. It seems to shift ok, occasionally if it's like floored from a start it'll act a little iffy on first to second but not really noticeable. Would replacing the valve body and fluid and filter help? Also what year transmission would work, it's a 2009 lancer gts auto with paddle shifters 2.4 engine. I'm finding it might be cheaper to buy a used trans and just take the valve body for mine! Thanks for any insight you can offer!
