Manual control valve is ok , checked
Governor valve - I only checked downshift solenoid and vacuum modulator and they are ok although solenoid has has nothing to do with it . I cannot check anything inside the gearbox as it is now installed on the vehicle. Do you know how to check governor valve ?
New oil is in the system , and sufficient amount , there is no leakage
Transmission air check - I only checked vacuum that goes from engine and it is ok
Band brake is inside gearbox and cannot check
If you have any suggestion what I can do while the gearbox is assembled and on the car let me know !
