hey guys my wifes s13 when we drive it sometimes it works fine and sometimes it wont shift out of first. if you are driving and it doesnt shift you put it in nuetral shut it off start it back up (while moving or stopped doesnt matter) then put it in drive and it works fine. sometimes you will be driving and it will shift down and wont shift up until you shut off and restart etc. im curious if this could be the auto control box?
