Sumping has nothing to do with the tranny fluid. Sumping is engine oil that collects in your engine and is not returning to the oil pan. If your tranny fluid is low, it may be transferring to your primary.
Thanks for clearing that up for me, Lots to learn with the M8.
I was not aware that I can do autotune sessions.
It only happened once in 900 miles.
Time to get out the SE Tuner Manual, Thanks!
It likely isn't the cause of what you experienced since it only happened once, but you should run a couple of autotune sessions to get the most out of your tune. Happy to help!
