Funny phenomena with stuff
You could try reeling the tmax from the other end. Cut off the center spool and reel from that side. If the roll has a severe curl to it, bending it back a bit (though not til it creases) helps.
With the fixer leak, the chemical reaction during that step causes a build up of pressure that will force fixer out of gaps. I also like to keep the tank lids off the tanks when not in use, the pressure fit seals could be stretched if they were always on the tanks and become ever so slightly loose.
