I have been messing with this leak problem for months now. i dont have any leaks anywhere else besides the output shaft. before i did the rebuild and shift kit, didnt have a problem. i now have a deeper pan(b&m's considered stock size pan) which side by side, the b&m one is deeper. i have it a little over full, and lately i have been taking fluid out, still leaks.it only leaks going down the road, wont leak in the driveway until just recently. which is making a mess of my underbody, cleaned it up the other day. i put in a new seal thinking the old one may be defective, still leaks, i silicone the endes where the seal and the aluminum is , different style seal where the whole thing goes into the end, no lip covering over the end ledge of the housing. still leaks a little.could it be that it is just to full

 

doubt it. might check the housing for any kind of defect(guoge in the sealing surface, crack in the housing.

 

no cracks or anything, doesnt leak at all where the extension housing bolts up to the tranny.

 

my buddys teacher at school told me to check the vent tube, i lower the tranny down to see it something was in front of it, nothing. l looked up there and saw a little fluid stream start to fall down the side ay the end of the tranny, not the ex. housing part end. looks like it might be coming out of the tube, too full then
