I figured this was a no-brainer...NOT! I looked up the correct cable in Rock Auto and they say NOT for TH400. I've got an automatic in my 1970 GS 455. There is no listing for the cable WITH auto. I went to the Wagner, Raybestos, and AC Delco sites and nothing. My spring is rotted off and the cable is not looking too good either. Any suggestions? Is there really a different cable for automatic trans?
