Mine says May 00 on the nameplate, and it has one. It is a standard grey microswitch on the far side of the fulcrum -- on a little bracket way at the top of the lever.

That's the kickdown switch for the transmission. If it is stuck down, your computer will throw a P1835 error.

I suppose if you want to test it, put your transmission in WINTER mode, then press the switch. That should cause WINTER mode to cancel, if I'm reading this right.
