In your OP you state the trans was "rebuilt". Anybody who rebuilds a 727 and doesn't replace EVERY seal isn't really rebuilding it. Demand that whoever did the work replace the shift shaft seal at no charge.

Chances are, if they didn't replace that seal, they probably didn't replace the rear band lever pivot pin O ring either.
