727 Hard to Roll backwards

Just noticed I forgot to link the thread I found on here with another person. I the same situation. Sounded like they had a washer that fell out while putting their transmission back together. Laptop I found that thread on is the in shop and I’m not going back out and seeing the gobs of work in front of me right before the car heads out for the final assembly (body shop left the front clip off to make re wiring and engine install easier).
