I'm not thrilled with the position of OD being in the neutral detent, but as long as there are positive stops in the detents it's a sacrifice I'm willing to make. I'm not ready for it yet, but will call and get my questions answered prior to ordering.

Thanks for all the input.

I tried and it does NOT work with the 4L80. The provided 4L60 shift arm down on the trans is the wrong length and when putting it into park it goes "over center"..

I am now running an aftermarket sifter with the optional shift lever for the 4L80.
