Hello:

2007 BMW 550i. Automatic Trani with 6 Speed Steptronic

Problem

I have the automatic in the DS Steptronic Mode. My car automatically shifts from M1 to M2 at 5 rpm. Well below redline and much sooner than I prefer to shift myself.

Is this a defect?

For the first 2 months after buying the car, it would switch to M1 by itself only at redline (7rpm)

Any thoughts on why this changed?

Thanks

 

Trying to understand the question completely.. Your trans in "Manual mode" (M1 etc) is shifting from M1 to M2 at 5,000 rpm automatically now instead of the normal 7,000 rpm automatic shift redline two months previously. Is that correct???????

In that mode the gears will only change if you redline them out..... because your supposed to que the gear changes via paddles or shifter. Thats a safety valve shift IMO. So, if the redline is lower now I would imagine that multiple factors are in play...maybe lack of shifting Not sure..but please clarify so folks here can help.
