Go 4.10s! You are definately feeling the vert/AOD blues. AODs are dogs enough, and I see you have a stock converter and AOD from your sig.? You wont go anyewhere fast until you upgrade those gears and converter to get that pig out of the hole and moving...
I have an AOD with 4.10s (non-lockup) and drive on the highway all the time. It burns a little extra fuel, but it sure is nice to feel the back of the seats when the pedal on the right side is mashed to the boards
