hey, i think my TC died. when i am driving at like 60 and tap the brake, the rpm doesn't jump. The BOO switch is suppose to unlock teh convertor right? the rpm is about 400 higher than it usually is, maybe 500. it is shifting into a 4th gear, so its not OD gone. what is a good one to replace it with? 94 1500 4x4, 360, stock everything. thanks guys.
