Is the BMW auto as good as dsg? Some reviewers have said the gearbox is a bit of a let down in the 135i
Its not DSG, which is a positive and a negative depending on what you are doing...
It's not the ZF8, regarded as pretty much the best slushbox you can get (sure it's not PDK/DCT/etc) but it is very good. The main thing is how it's configured, the old F-series Mxxxi for example was a very different state of tune than the rest of the range.
So, what you have got is the Aisin 8G45 8speed auto, which by all accounts isn't quite as good as the ZF, but good enough and does have M specific tune and ratios. It'll at least hold a bloody gear until you say so, rather than auto upshifting... more than I can say for my DSG
