904 squirting

Hey!

Just replaced my 904 after burning the cluch (i think) with another used 904.

It seemed to be working, but made a loud rattling noice while the trans was in (neutral, drive, reverse) at first. Could sound like a bad bearing somewhere but it disappeared after running in neutral for a while.

I started driving very carefully to let the trans get its components running easy and getting lubricated etc. (it haven´t been used in 8 years or so). It seemed to give the engine a little resistance and shifted a little to firmly into drive, but otherwise seemed to be running ok.
After a while it started to spray out the fluid while I was driving, so I stopped in in a side road and let it cool down. Then I refilled it with fluid and started up again, and as soon as I put it in neutral it starts splashing out again.
I couldn´t see exactly from where it came, but it looks like its somewhere in the the area probably right above the pan, on the drivers side.

Any ideas here? :S
