Thats the beauty of a TurboHydramatic 400 like in the '69. Its modded and has around 100K on it with 400 lbs TQ or better the whole time, two engines so far. When it does that it just means I've let it get two quarts low ha ha. Add fluid and burnouts ahoy with big tires! Oh well, I have the one I pulled out stashed and it did still work.
