i have a 96 lsi and i had a truble code 14 for the trany, bad wire so i fixed the wire. now i have more codes. has this happend to anyone else? dose this mean i have a bad TCM? i realy dont want to chase all of the codes and find out that its just the tcm. the new codes are 12,13 and 23. i have a good manual so i know what they are and how to trouble shoot them but would rather just know first.
