I Have a 1994 legacy, 5 speed manual. It has suddenly started leaking lots of oil from the transmission. The leak was coming from inside the bell housing. I pulled the transmission out thinking I would need to fix the input shaft seal. It turns out the leak is coming from a hole between the two sides to the trany case. The hole is just under the input shaft. ( see photo) What could cause this? What should I do?
Thanks for your help.
