when I picked up the KA24DE from "jay" lol it had that sensor on it, I believe them sensors are ment for 5spd manual tranny's
the one on the left is from the vg30e OEM, in which I believe for an autotragic, I also replaced that oem with one from rock auto, which is what I have on there now. It shifts soo much better especially I got my passing gear back for the slow old guys on the highway that wont drive faster then minus 10 - 20 mph from the posted speed at 65. or the constant bottle neck at the i-15 / us 95 here in vegas at rush hour. To a point where I Squat when I hit the throttle at 45 now instead of being bogged down touching the gas.
