TH400 Auto Transmission Tail Seal Replacement 1970 C3

Not done this job, before but have a very small but annoying leak from this tail seal, has anyone tried a transmission fluid leak additive cure i.e. Blue devil or Lucas and found it worked as this would be a easy fix as I do very low mileage each year.
Otherwise is looks a relatively straight forward DIY job with trans left in car; is there enough room once prop is pulled out of the way and do I need to remove the cross member and exhausts to do this comfortably; any tips welcome

Also anyone know the cost of getting a garage to replace this seal?

Kind regards
Paul
