If you think the ZF 6HP 26 is good in "standard" BMW guise you should try it with the Alpina programming
Of course only Morgan and, I hope, BMW, know the programming used on the Aeros.
I suspect it is bespoke as the paddle shifts don't function in "normal" gear box mode, but are active only when the box is in "sport" mode. On a standard BMW the paddles work in both normal and sort mode.
Shift points are very different, the car is much nicer to drive in sport mode. I tend only to use normal mode in traffic as the throttle response is softer and it is easier to waft gently along.
Also in sport manual mode the box will not force a change up until the red line is reached. When changing down there is a very noticable "throttle blip", not needed but very nice!
The Auto box has very different ratios from those in the manual box, with 4th as 1:1, so both 5th and 6th are overdrive ratios, resulting in quite acceptable fuel consumption. It is no worse than I got from the Roadster. The manual box has 5th as 1:1 (differential ratios are the same). With the amount of torque available and the light weight of the car I feel that the auto box matches the car better than the manual one.
