Transmission leak

I have a leaking Transmission and can not find where it is coming from. I have a 1995 Saturn s series with a manual trans axle. It has been leaking for about a week. I changed the right seal because I couldn’t find any other place it could be coming from. ( the left seal and speed sensor were dry.) This did not fix the problem. I am sure the seal is in good and it doesn’t look like the oil is coming from the seal. I don’t know where else to look to fix this leak. also after changing the seal I have a strange noise when I am in 5th gear, but only when I apply the gas.
