However, it does take longer on a flat road (with steady throttle position) to get to OD and it doesn't take much additional throttle to get it to drop out.
Note that I do have a 3.73 LS rear end.

Is there a way to lock the OD out? Possibly a D1, D2 position for the shifter? I can see how this would be desirable if the transmission was constantly shifting up and down. But, I've never been one to subscribe to the adage: "Don't tow with the OD on." If lower gears aren't needed, might as well save gas.
