Thanks for the updates.

So the "S" manual and automatic (D) mode are controlled and operate as OEM just modified for faster and sharper/firmer up and down shifts. And the "W" mode remains unchanged. Wet or icy conditions switch to "W" mode, if normal driving condition leave in "S" and drive in auto (D) or manual, car shifts are normal RPM based up on throttle position. Is this right? sorry for beating a dead horse here.....

Everyone is still happy. I don't see a down side to this mod.

I can order one plus a core, install, test, and send the original TCU back for core refund?
