I actually had a trans filter plug up with debris on a Dodge demon I used to own. The symptoms were start up cold and vehicle drives normal for about 300 feet the goes to neutral. Still had reverse and made many runs to the beer store in reverse lol. It was actually a friend of mines car. Well the friend gave it to me and I serviced the transmission. Had sludge and what looked like leaves in the pan. New filter and clean pan the car ran and shifted like new. I drove it on trips out of town after that till i sold the car.
