Not sure I'm following. A kickdown cable is just that, it'll kick it down to a lower gear when you're trying to pass, or get on the gas.

It will do nothing at wide open throttle.

As long as you can shift at the rpm you need to. Look elsewhere to better your et's.

but if he left it in drive it will shift early.. That would be my guess, since we don't have all the info..
