Unhappy lockup converters

Hey guys, my 85 k5 blazer, 305/700R4, all stock. At about 45 mph, the overdrive kicks in and the torque conv. locks up ok but around that speed and beyond, it jumps in and out. A real nuisance you know. Do you think the vacumn switch on the firewall is bad? I can't find any vacumm leaks. Boog.
