LOUD Transmission drone at 58-62MPH

New to the forum, sorry if it's on the wrong section. I googled keywords about the issue and came up a thread on this site but no one answered on it.

Issue: Loud tranny drone that's equivalent to having your brains lasered through your ear canal

At speed between and near 58-62 where 60 is the peak.

It's NOT engine related, i've ruled it out.

It's NOT tires.

Source of sound is the tranny because i hear it next to me just behind the dog house and drilling through my right ear.

It's only under load, IE, part throttle or full in that MPH range. Goes away if you let off accelerator within those ranges.

Will also note, sound is not existant when decelerating in those ranges downhill.

Vehicle:

1994 P30 Chevy 454 TBI.
Don't know what type of tranny but gear selector is 1,2,D and D with circle around it.

52k Miles.
