Pulling the tranny from one truck today. The manual says to put a floor jack under the oil pan of the engine to help support it when you remove the tranny, and i'm assuming they are recommending leaving the jack there. Just wondering how critical this is. I have to push one truck out of the garage after I take the tranny out. Then i'm bringing home another from 6 hours away without the tranny in it. I'm assuming the engine is not blocked up. Anyone have any experience with the engines stability with the tranny removed?
