i replaced the tranny seal on the driver side twice now the first time it didnt leak for a few days but the second time it leaked in .3 miles what could cause the leak other than the axle

I had the same problem a month ago. I'm looking for an answer as well. My leaking started slow, then there was a noise that sounded like a wheel bearing but the wheel had no play. The sound and leaking got worse but no wheel play. Turns out, there is a bearing, or something right inside the transmission, making the cv joint move with every bump. Is that replaceable after the cv joint and seal are removed?

You sure you don't have a bad CV joint?
It's not very common for the bearings inside the transmission to go bad.
