Transmission in M mode upshifts without input?
Hey everyone,
I am experiencing a weird issue where, when using my Individual mode - M transmission mode and engine in Race, the car will intermittently (1/50?) shift up 2 gears after I click the upshift paddle once. At first I thought I was going crazy... like "did I just hold the paddle too long?" So I tested and tested and now I've experienced it from 2-3 and 4-5, always under mild throttle. Not seeing any codes and the car otherwise drives fine.
Has anyone else experienced this? I did a search and didn't find anything.
Thanks

In race mode the transmission is sort of Manual/Automatic. That yours is shifting 2 gears after using the paddle doesn't sound right, but automatic shifting does happen in race mode even if Manual is selected. If you want ONLY manual shifting you have to use Sport or Comfort in Manual mode.
I think.

Most likely a worn out shift paddle switch, so it bounces and gives duplicate shift commands. It's not all that uncommon.

^This. If anyone has the part number please let us know. I'm also going to ask my mechanic for it.
