That's assuming the auto box in the M135i is a plain vanilla ZF A8HP45, which we don't know for sure.
While mindful of the torque issue, we need to take care about stating this as a fact, and creating, potentially, another "internet" myth.
The actual gearbox part number is GA8HP45Z. Now, one of the design features of the ZF A8HP 'box is modularity, meaning each model allows for a variety of configurations and applications. Has BMW specified a custom version? Don't know, but given Chrysler has a couple, it's quite probable.
In any case, it seems absurd to assume the box in the M135i
just meets the engine's output, with no headroom!
Does anyone else have any information on this issue?
