Critterman:
I don't think so, but who knows

GJ said he sent the unit to you, you are going to have to take it up with him ;) I would send you the test unit that is in my car, but after driving it for awhile, then driving the other cars we have here without it, I don't think the prototype is coming out of my car :)

Dave, will this help smooth out the shifting of the AR5? My JPM shifter gives me more of a direct feeling of shifting, but it didn't change how rough the AR5 has always shifted.

Have to admit I giggled a bit here. I know the DDM Dave has 'magic hands' (just ask Ivy!), but there are limits. :) After all, he's not changing the internals of the transmission.

But let's stop a moment (hah!) and go back to elementary school physics and the theory of levers. A lever applies 'mechanical advantage' such that the long end moves the short end by amplifying the applied force at the expense of distance of movement. With a 'short throw' shifter, you have to make the short end longer, and so are effectively moving the pivot point on the lever to make the long end relatively shorter. Thus, the long end doesn't move as much as it did before to shift gears, but at the expense of increased force needing to be applied to shift. Thus, it's likely that the gearbox will feel even more 'clunky' and 'notchy' with a short shifter, rather than less so.

Yeap, simple physics. I love the short shifter now that I have had it on for awhile.
