transmission pan and rtv sealant

had a really bad trans pan leak on a '95 940. have a very slight leak after a meticulous job of inst a new pan gasket. is there somewhere around the linkage or some other place at the trans body i could still be getting a slight leak? also, does someone know of a really good high temp gasket sealant other than rtv. it seems to take a set too quickly esp. when a lot of bolts are involved. thanks

oil leak 

check breather on auto box is clear maybe pressure build up ps did you change filter when pan off another cause of excess pressure
