2004 Dodge caravan
The transmission down shifted and then mad a clunking noise. I pulled over
and it seamed to go into park but shifter was in drive. When it wouldn't
change to neutral when stopped, so I could push it off the road. I had to jack
it up and play with the wheel and shifter to get it to move. I had a wrecker
take it to the house .now when you put it in gear it it will jump ahead but never
move when accelerate. What could be the problem?
