I only started noticing after they applied some mystery firmware update to the transmission back in Oct. My service receipt says " PERFORM RECALL 331108 - SPEED TRANSMISSION TURBINE SHAFT FAILURE CAUSE : 33110 Perform Transmission Control Module Reprogramming with SPS ward code 18C41"

Thing is I'm not sure if the update caused this or if it was always there and is otherwise normal. I'd like to see if anyone else has had similar experiences.

Same issue here too.
