I have a 66 chevelle with 396 powerglide and the trans pushes the fluid out when car sits in the garage for more than a week it does not appear to be the front seal or rear seal it appears that it is pushing out around the pan gasket or ??? Is there a vent somewhere on the trans that could be the problem.

Try to check your dip stick tube seal,common for PG to leak there due to a dry or cracked seal.Then put a cast aluminum pan and rubber seal on it.Stamp steel covers leak often.Good luck C-yaaa Vince
