Hey everyone I'm new I just got a 1996 deville three days ago all was good then I got a service Transmission warning and I got a Diagnostic Trouble Code of PC0717 current well when I reset everything now it reads PC0717 History what should I do.

Sorry for the bad english lol

well you can buy a code book to look up your trouble code.but if i had to guess the owner be fore you cleared the trans code because a modual inside transmition is bad 94.00 for modual and 1,500 in labor if done by dealer.
