So recently my automatic 4cyl 04 mazda 6 has had issues shifting from 1st to 2nd and from 2nd to first. it sounds like its just hagning up but what could be causing this? I have the manumatic option the tranny works fine in that setting its just a problem in auto-mode. I have done extensive searching and cant seem to put my finger on what it might be. PLEASE HELP!!!!!!!!!!!!!
