TC lock/unlock

I've had classic intermittent TC lock/unlock problems typical of my 99. I've installed the BD noise filter, wire brushed/dielectric greased all grounds, aluminum foil on battery cable, added extra ground cable from battery to PCM screw on firewall. This seemed to take care of the problem until yesterday.
Made first tow yesterday since my repairs with my 7000lb horse trailer through our local mountains and the lock/unlock problem came back but worse than before. O/D off or on.....it made no difference.
After dropping the trailer the problem went away. Any ideas what is going on. I'm at 99K miles with a mild box.
Any input would be appreciated.
