While going up the ledge shown above at a relatively slow steady crawl my front end got light and lifted off the ground. I've been told my front tires were about 2' from the ground although it didn't feel that high. There are no pictures as everyone was running for cover as the general thought was I was going over.
The odd thing was that for those few seconds I had no tranny control. When I touched the gas to try to provide some throttle input the motor reved, but nothing happened. I had no forward or backward power from the tranny. Luckily the truck settled down on its own accord and as soon as everything was at reasonable angles (all wheels back on the rock face) I had control again.
My JK is a '07 Rubi with an auto. I have wheeled two other auto equipped vehicles (and several manuals) in similar terrain and never experienced any sensation like this.
My initial guess was that tranny fluid pickup was exposed and sucking air. Does that make sense? Or maybe since the JK is computer controlled, it was taking over? Thoughts?
