Leakage needs to be traced to pinpoint if origin . If its really the plug a little permatex number 2 on the plug before insertion wit the plug and hole clean will do the job. You could have leakage from the torque tube or housing mating joints . Snug all bolts . You could drain and remove the Lowe bolts 1 or two at a time and use a little bit of rtv or permatex 2 on the bolt threads , same with torque tube . If its a 28 housing I have seen a number if them leak from pinholes where the two pieces were welded .

Best of luck
