This eventually happens with all helical drive Maytags (after many, many years).   It's the o-ring seals on the input shaft of the transmission.   While I've never done this repair, I know it's a pretty involved, requiring complete disassembly of the washer and the transmission.

I'm pretty sure any appliance repair shop you contact will tell you A: it's too old and not repairable, scrap it and buy a new one, or B: parts are not available, scrap it and buy a new one, or C: they are not willing to work on it, so scrap it and buy a new one.   In other words, it's more work than they are willing to do.

These can leak (slowly) for many years before it causes any problems with operation of the washer, other than leaving greasy mess on the floor under it.   If it's only leaking small drips, I would say just keep using it, unless you have the knowledge, ability or desire to repair it yourself.

Roger what is the model # of your MT washer, If it is built after about 1990 and has the orbital transmission it is fairly easy to replace the lower transmission oil seal. If it is the earlier design it is a very big job, it is often better to just clean up the oil as often as needed and keep using the washer until it stops, often a MT washer that leaks oil will run as long as ten or more years before it dies.
