hi i hope i posted this correctlly. my sport light started blinking and it will not take off in d4, so i tried manualy shifting and no 1st or 4th gear it will drive but taking off in 2nd & then driving in 3rd. I also tried to pull the codes by jumping the wire under front right passenger floor board and two short blinks from sport light , i heard the d4 light is for the tcu & check engine light for the ecu, if this is true why is the sport light giving me the two short flashes? the d4 light works when i put in 4th gear so i think the light should work for codes . can someone help me please thanks
