The switch is OK. No flashing of any kind, if it isn't me moving the switch.
The indication also works. It simply won't shift up!
Three upshifts with the OD on. Two with it off.
I do about 3,000 RPM at around 65 MPH. Normally, with OD, I get 2,500 RPM.

The Cabernet colour seems a little odd for me. I originally thought is was some form of magenta. I have never seen that colour on a car before.
