I have a 1989 BMW 325ix with an automatic transmission. I recently replaced the output shaft seal and the transfer case seals (the one between the transfer case and the transmission). After refilling the transfer case with fluid, it has started leaking from a small hole located between the transfer case and the transmission. I'm not sure if this hole is original or was made accidentally. Can anyone help me figure out if I installed the seals incorrectly, or am I missing something?
