700r4 TQ lockup goes Rapidly in and out

41 Willys coupe, 350, 11;1, large comp cam, 2x4"s (Holly 465) on tunnel ram. 700r4 with TCI lockup kit, 3500 stall TQ, ford 9" 390 gears, 30" M/T drag radials.

The TQ will rapidly lock and unlock even between 70-80 on the interstate. Didn't have this problem with the old 1200 stall TQ. I know, 1200!? It was defective, suppose to have been 3000 stall. I've checked the TV cable a couple of times and it seems to be correct. I have it wired so I can turn it off by a rocker switch on the dash and through the gm brake light/cruse control switch. Checked wiring and it all seems to be ok.
I'm thinking internal 4th gear switch?
