8th gear issue
Anyone experience an issue where the auto won't hold 8th gear? It shifts up and stays there for about 15 secs and then drops back to 7th. Car's done about 9k, when searching it looks like there's been issues on the g80/82 and some X's.

Does it do that in all modes? It may be programmed to only stay in 8th in D1.

How fast are you going when the car shifts back down to 7th gear?

We have had 3 ZF8 BMW's and have never experienced this so I'll go with Aramis1919 - Under what driving and transmission loading conditions does this happen?

This is my 3rd with a ZF8 too. Never had a problem with it up until now. It happens in efficient, sport and sport plus, while in road and sport using D1 or D2. Up until now I've been able to get into 8th at around 65-70mph, which it still does but drops back to 7th after a few seconds. Will try some of the options here -https://g80.bimmerpost.com/forums/sh....php?t=2013153

For anyone who develops this issue, it seems to rectify itself over time. In my case just over 700 miles or a few weeks. It fixed itself before I was able to get it into BMW. I'm so glad it has, as the car was barely getting 200 miles out of the tank.

All my driving behavior is, are short runs and low mileage. My guess is I’m a good candidate for this issue. Guess I’ll find out.
