john deere 444h

I have a 444H the park brake will not release no forward or reverse the bucket functions all work and it steers the fuses are good and the switch is new and tests ok and powers through the switch I’m waiting on john Deere to send someone out but it could be over a week or more to work on the unit. The input bearing on the converter is making noise but I don’t want to pull the engine until I know the Trans is ok
