transmission issue on my charger?

Question

i've got another question for all of you tonight about my project 1970 dodge charger. today we started it up, and it fired right up, sounded great, everything was cool. then after idling for roughly 8 seconds or so, the car started rolling forward and fell off the front jack stands and started rolling into our garage from the driveway with me standing in front of it. it scared me. when i bought the car, the guy said it supposedly has a 727 torqueflight trans, but the linkage when i looked at it, is all messed the hell up. my dad told me the car wouldnt start if its stuck in drive, now... whats going on here? it didnt start moving until like, just a few seconds later and it did fire right up, we are all so confused. how can i get this all fixed right? i dont own a manual and i just wondered if anyone on here knew. thanks for the feedback. i love you guys. you people have helped me alot. and here's a link for the youtube video of it, so u can see. http://www.youtube.com/watch?v=k9r8i5Z6Vww

Answer 1

It could be one of two things one your linkage is messed up and it is causing your reverse and third band to engage or second you have a bad neutral safety switch or a wiring issue with your neutral safety switch.Both problems should be fairly easy to resolve.I watched your video it looks like you have a big job a head of you as far as bodywork goes but I've seen far worse looking cars restored.

Answer 2

If it has been sitting for a long period of time, the clutches and bands may have rusted and are sticking.
I had basically the same problem after a rebuild because the intermediate clutch plates were too thick. The vehicle would start and drive away in neutral.
Start it up again holding the brake and shift through the gears and see if it will come loose.
If the neutral-start switch is working properly, it should only start in Park or Neutral.
