I don't think this would happen during normal driving since the speed and vacuum logic should prevent it. The transmission would likely already be in 3rd above 50mph and light throttle. I could see it happening if you were shifting through the gears manually at light throttle.

I don't think it would be a problem (Especially the way I drive!) I have driven in second overdrive while towing up steeper grades but the vacuum should keep the converter unlocked and if it is a problem I could deactivate the lockup circuit.
