Thought it was leaky pan but now...

Just wrapping this thread up. Recap: I first took it to a mechanic and had him replace the tran filter and gasket. Leaked. he tightened up again, leaked. said linkage seal was bad but he can not fix.
Had car engine rebuilt, that mechanic was going to fix it for me, until he realized he would have to remove the valve body to get to the seal, so he didnt fix it. Leaking pretty bad. Last week took it to Aamco (yikes, right) where a father son team run it and have lots of old cars around. He says he can fix it. Gets it on the rack and says linkage seal is leaking and the pan gasket is leaking. He removes pan, hammers it out a little, replaces linkage seal, replaces gasket, careful not to get too tight. And now no leaks. $150. and he said bring it back in 2 weeks and he will recheck it to make sure all is well.
