46RH making noise in Park and Neutral

The torque spec for the filter screws on a 727 trans is 35 inch pounds.

I use a 5/16'' combination wrench [4'' center to center] and a fish scale. Hold the fish scale at a 90* angle to the wrench and pull to 18 pounds. [4'' x 18 pounds == 72 in-lbs] Then back off the bolt to the spec for YOUR trans.[usually about two turns]. Hold adjusting screw and tighten lock nut to 30 ft lbs. for front band and 25 ft lbs for rear band.

My trans also makes a light 'buzzing' sound. Same sound for 2 decades now.
