The 1M also has this same "down rated" manual trans(as do all N55 135i's)... even though the 1M puts out 500Nm. I think either BMW figues not too many trans will fail under warranty or they know that its ok. Maybe its just the bean counters taking over at BMW. BMW did say that one of the reasons for going with the N55 engine was it was cheaper to produce - besides being more economical on fuel than a N54.
