Our TYM has about 1000 hours on it. It had a fuel leak when it was new which took only minutes to fix. It never saw a dealer or needed a part except persistent leak from sight window on the transmission. I replaced it three times already. It will be OK for some time and then it will start leaking again. I tried to glue it, seal it but so far with little success. Beside that it is a workhorse.
try shoo goo or automotive goop. Silicone with glue. Good stuff. Obviously make sure the surfaces are clean and dry. I usually use alcohol to clean first...
I am truly impressed with these "goo" products. I bet that will work, as long as your surfaces are clean,clean,clean and dry. You'll probably have to drain the fluid down first.....
I tried epoxy and oil pan sealant so far. I will give it one more try.
