Having a guess at something here, can the box shift into a lower gear if the lever is held, ie if you do not release it quickly enough?

Yes, I wondered if holding the lever may drop it down two but I don't think it does. It only ever does it from third to first, never anywhere else or changing up for that matter.

It could well be that it is seeing two commands, one from you and one from the box. |

Holding it doesn't drop it further down the gears

I also mainly use command shift, mine does the same thing. What I noticed is that when you change from 3rd to 2nd but your within milliseconds of the gearbox forcing the 2nd gear it then drops to 1st, this puts you in the wrong gear for speed. it is as if the box has made its mind up to go down a gear but you just beat it to it and the computer is too slow to realise you have taken the gear whilst its in the process of doing just that.

How do you do a hard reset then? Wurzel, it makes sense and that's exactly my thinking. It drops only one gear when the speed is higher, if changing when the speed is lower then it drops two. By the sounds of it, it is a characteristic of the gearbox, although an annoying one, which can be worked around. I will try the reset though to see if that helps. Thanks all. |

Take off battery connections hold them together for a minute leave for a few more minutes reconnect and reset windows. |

We have a winner You are selecting a lower gear just as the car decides it wants a lower gear, and so 2 changedowns happen |

Connect together both leads, you sure that there will be no damage to hardware due to residual power etc? |

A case of man verses computer with the sound of it, it wants one thing and you want the other both at the same time.

I think it is slightly more efficient when changing gears yourself but that is not the reason I bought an auto.
