ERS is the acronym given the paddle shift function. I've found that if I'm entering a highway that's posted for 70 mph and I go to no-throttle at 60 mph the trans will shift to 7th then 8th. The tach will show the steps. Then slowly (and I mean VERY slowly) accelerate to 70 it will stay in 8th. If I give it just a little too much throttle and it downshifts to 7th I can't get to 8th again unless I drop back and go through the process again. The controller just doesn't recognize when it's appropriate to use 8th. While driving (at 70) if traffic slows to a point it downshifts to 7th, once I get back to 70 it will not shift back to 8th. I have to use ERS to manually shift it. It's pretty obvious the programming is not correct as it relates to the use of 8th gear. It puts a lot of distraction into driving if you're trying to get the best overall performance. Automatic transmissions shouldn't require that kind of interaction while driving. Hope that helps.What is your method of getting it to hold 8th and what is "ERS" you mentioned a bunch in one of your above posts.
