Post 700R4 losses reverse after towing on a dolly?

Last week in my haste to get to a hybrid event at my local track I rented a tow dolly..I know that you were supposed to pull the driveshaft to prevent tranny damage but i didnt have any fluid and was plain cheap/lazy..When i arrived at the track the car wouldnt move in reverse..It was like it was there and then went away..Now back at the house i have to rev it way up to get reverse wich is really weird..All the forward gears work great and it even shifts automatically fine..Im not sure if the trans was in netural when i pulled it and im thinking just a band is worn out..Possibly backfeeding pressure through the fluid while towing..Any insight would help..

Automatics are not self lubricating like manual transmissions. They are lubricated by the front pump which is turned by the engine...yup, you broke it.

Without the engine running to turn the front pump there would be no lubercation to the clutches or bands. it's just a matter of time with all those parts spinning around that things will burn out. There's probably isn't any friction material left on the reverse clutches. All you can do it rebuild it.
