Transmission Problems? Ask a Mechanic for Answers ASAP
You will need a scantool to retrieve the codes from the TCM.. A code reader will only retrieve the P0700 which only tell's you that you have additional codes in the TCM that need to be read. Once you have the codes post them here so i can see what's going on..
Then you will need to see if your local Advanced Auto or parts store will read them free of charge and post them here.. You can't repair your transmisison until you know what's wrong..
