While driving home from work yesterday I happen to look down at my radio and saw my OD light flashing. I was doing about 65-70 and did not notice and shift problems until i got off the exit and noticed a very slight bump when it was going into 2nd and then third gear. I pulled over shut it off then back on and no more light or bump i drove around for another hour and it never happened again. then again this morning at the same speed it did it again so i again cut it off and started it back up and it went away i have been driving all day with no issues. where are the codes stored from the tranny? i went to auto zone and got the cel scanned and got a code p0401 and something about bank one oxygen sensor. any ideas?????
