automatic (push button 727) front seal leak ?

My 67 TF904, last overhauled in 1984. Sometime around 2014 the selector shaft seal started leaking. I fixed that from underneath. A few months later the front seal started leaking. I'm not able to drop the trans and replace that seal. I've contacted 3 local trans shops and all 3 said same thing, "It's all the same age. It has been ran with low fluid. We dont want to help you make a foolish move. We'll overhaul it for you, ranm'd torque converter, addon oil cooler, and warranty." I have accepted that as the best plan. Good luck with yours.
