tranny leak problem
I put in 75/90 gear oil in tranny, think I messed up. I have an oil leak just the tranny for now. seems like it is comeing from the pan. I changed the o-ring just hoping but still bad. would a bad oil pan gasket cause the tranny to leak. should i drop the pan and change the gasket. or could there be another cause. wondering if the 70/90 could have caused to much pressure and blew out a seal or gasket. or crap i doun't know.
thanks guys

You sure it's not simply residual oil laying on the frame crossmember?
On my bike it's hard to drain the tranny oil without flooding the crossmember so I shove rags between the crossmember and the pan to prevent this.

I can't imagine what could be causing a stream of oil to be leaking from doing a simple oil change. Wish I could be more help but I haven't got a clue.

I agree that just changing the oil is not going to blow out a seal or gasket.
Either the o-ring is leaking or residual oil is dripping off the frame.
Also check the crossover pipe hanger bolts behind the oil pan.
