I’ve got a 99 R/T with a disconnected transmission cable. I traded for this truck a couple of years ago and have had no major issues with it since. One day I crawl underneath it and discover the cable has been disconnected. So I hook it back up. Then the trans won’t shift out of first. I redisconnect it and everything shifts out fine. Now I start reading that’s a big no no! I’m pretty good with most mechanical things but transmissions are a little foreign to me. Any help would be greatly appreciated.
