is your lockup switch lighted or wired thru a light so you can tell if the solenoid was working when you were driving?
why I ask is:
the rpm drop when the lockup happens is not much. on my truck with a basically stock 350 and 3.07 gears I can definitely hear the exhaust note change. but in a friend's equally loud truck with a 454 you couldn't, it just didn't affect the engine that much. maybe with your gearing the extra load when it locks/unlocks is not enough to sense
The switch is lighted when it's turned on, not when the solenoid engages. The D pin is grounded to the chassis, B is cut off and not hooked up. When I jumped power to A I heard a click, but only once, I couldn't replicate it. Maybe has to be driven to disengage it?
With my gearing I can definitely feel when it is licking up or not.
