Comment 1
ok, checking my trans fluid and adding fluid to it will that help or hurt it? -
Comment 2
Check fluid with engine off and on level ground.......'d' light flashing means there is a trouble code stored in the trans. control module. Need to have that scanned (generic OBDII reader will NOT work) with a scanner capable of communicating with acura powertrains. -
