I took apart my Whirlpool washer for a dripping sound. That problem was probably the faucet, which was fixed. Now I have the washer open, I noticed a black oil residue on the floor - a small patch - and sprayed yellow oil on the lower half of the inside of the cabinet and on the frame rails. I thought at first the black stuff on the floor indicated a coupler wearing; but no, I think it's oil (having ordered a new coupler!) I have a fear this may be a transmission seal. Washer is a top load, 9 y/o, and only problem to date is recently chewing up a synthetic blanket.
Considering a new washer, b/c I'm concerned once I get into the transmission, something else caused that transmission problem. Any ideas?
