Hi, I saw a small drip from my rear seal on the transmission so I put a new seal on

Even after installing a new seal, the leak is still there

?????????????????????????????????

is there something i need to do.
the transmission works so its not a big leak just a pressure leak I guess.
is it normal to drip a little from the rear seal

What year Dodge and transmission?

1996 dodge ram 3500 5.9L v8
46rh transmission
