Usual water leak from the tub seal after a few years. This allows water to seep between the tub bearing and the transmission output shaft destroying it and allowing water into the transmission itself usually locking up the bearings. I was fortunate. The transmission, although extremely noisy, wasn't locked up. The transmission output shaft is used as the surface the tub seal gland wipes against. Due to the zinc transmission casting, the surface the seal contacts was also corroded and 'grooved'. With a brand new tub seal installed, it still leaked due seepage past this groove. Normally, a new transmission would be in order. I repaired the old one using .008 brass shim stock and silicon RTV type sealant. Choice here was $200 for a transmission on a 5 year old washer or $69 for a piece of shim stock from the hardware store. Coat the housing around where the seal sits with a thin layer of RTV and wrap a single layer of shim stock around it secured with rubber bands until the RTV sets. Using an xacto knife, cut off the excess shim forming an extremely accurate 'butt' joint. Give it a once around with emery cloth for the sharp edges. This provides a new brass surface for the tub seal gland to press and seal against plus filling the corroded groove with the RTV as a backing. Since the tub bearing is also severely corroded with excessive clearance slop allowing the tub to wobble wildly on spin, it too needs to be replaced or repaired. As-is, the new seal would be destroyed in short order. Ideally, one would replace the it but seeing as how it's a big job and the machine has other issues, it wasn't worth the effort to me. Cut the remaining shim stock into 1/8" or so strips about 1" long and feed them down, one at a time, between the transmission output shaft OD and the tub bearing ID while forcing transmission shaft in the opposite direction until the excess slop is taken up. Oil or grease the shimmed bearing and the repaired transmission shaft liberally then reinstall the tub an usual. As a safety measure, apply RTV to the transmission spline shaft where it fits into the agitator making a air tight interface. This will 'bubble' the transmission bearing and seal area away from water contact not unlike a glass turned upside down in a pan of water. Should head off additional problems. By allowing oil to 'seep' into the transmission along side the seal on the spline shaft when it was apart, it too was repaired and is no longer making the screaching noise when spinning and does it's normal amusing "Texas Two-Step" when washing that it hasn't done in a year or so.
