Correct, if the idle did not go to 1200~ then the process did not happen. The idle comes up so there is sufficient line pressure to cycle all of the clutch sets.
How much should it raise?
everything seemed right except the the rpms not jumping up. the M showed up for short period then went to M1. I will give it another go later today. I attempted it yesterday after a 16 mile drive with one spurt up to 90mph and did a fair amount of manual shifting up and down and keeping the revs up for a few miles, so should have been plenty warmed up..I was using the one thousand one one thousand two method for my timing which actually corresponds really close when I compare that to my stopwatch.On my 2016.5, the RPMs go up from idle (~800) to about ~1250 or so. That's when the "M" shows up on the dash display. When the display changes back to "M1" the RPMs drop back to idle speed.
Certainly sounds like either a step was missed, or that those specific steps don't exactly match what a 2023 model requires. (I've only tested this particular procedure list on a 2016.5. Uncertain whether it perfectly works on any other vintages, as I haven't tested them.)
