Jim, not having an auto what about this? (m)
Assuming it's an auto aren't the wheel sensors used to also tell the tranny when to shift?
It could be possible that the tranny is in 3rd or some other gear making it had for the car to get moving, just a guess.
Gordon, stay safe, safe travels home. One of our's was in Iraq on a 4 month mission. I saw pics of a lot of places, the sand blows right into closed buildings thru any opening no matter how small it is.
