On the stereophonic transmission on the e53. I know if you are in the manual mode say M3. You are in the 3rd gear and will not upshift (to M4) until it redlines, right???? Please confirm.

My question is if you are in M4 and you start to slow down does it down shift????

If it does not and if you stop or slow down to a dead stop then you are starting the car or going very slow at 4th gear??? Is this right???
