    8 speed vs 6 speed creeping

    Has anyone else who's moved from a 6 speed to an 8 speed XF noticed a difference with creeping? I've come from a 2012 6 speed XFR to a 2015 8 speed XFR and am finding it a bit weak

    I've noticed it slightly over the few weeks that I've had the car, but today I had to do a parallel park reversing up a hill and struggled a bit. In the old car it'd just pull as I let off the brake wherever it was, today I found myself rolling forwards and had to use the parking brake to hold it until I got the revs up a bit so it'd pull backwards. I've noticed the same when driving up the slight slope on my drive too, the old car would just go but this one sits there or rolls very slowly until I use the accelerator.

    Is this normal or something I should be getting checked?

    Have you tried it with Dynamic mode enabled?

    Now you mention it, I think I had something similar recently. Didn't really think about it at the time. Not aware of anything else out of order, so would just see it as a 'feature' of the newer box. It's different.

    Try manually selecting 1st with the paddles. The 'box will default to 2nd for "normal" starts, only if you clog it some will it actually drop into first (or are in Sport IIRC).

    No, should it be making a difference to creeping?

    I was trying to go backwards, selecting 1st would have guaranteed hitting the car in front

    It changes the throttle response so maybe?

    I've never found a problem with the car rolling back when on a hill.

    I've not had it roll back in D either I don't think, but it doesn't creep nearly as easily as the last one. This was rolling forwards when in reverse, which is definitely something I've not had before. It felt quite like driving our Audi A1 with S-Tronic, there's a delay before it actually engages a gear and I'd need to use the hand brake in the same situation to stop it rolling forwards.

    LOL, well, at least if you want more "creep" forwards, you have some ideas!

    I've only ever had the 8 speed, so can't make a comparison. I have noticed a very slight delay at times when moving off though. Does the ZF 'box have a 'neutral-shift' feature? I've thought I could detect a very slight change in revs as if the load was taken off the engine. Years ago, my Vauxhall autos shifted themselves into neutral when stationary for more than a few moments, e.g. at traffic signals. Drive re-engaged almost instantly when moving off, but it did feel a bit strange at first.

    It's just a feature of the gear ratios I think. The 6 speed starts in first, the 8 speed starts in second unless high demand or manually selected. So you will lose a bit of torque there too.

    6 speed starts in 2nd. I have to shift down if I want a quick get-away. 😕

    I've had 6 and 8 speed. Can't say I noticed any difference to creep. Slightly different idle speed would make some difference.

    I've been trying to find a bit more information about the ZF 8 speed transmission and have been trawling the net. As with all things on t'interweb, I don't know how accurate the data is, but it seems that the 8 speed does indeed have a 'neutral-shift' capability.

    Taken from an Australian web-site: "A new innovation of the 8HP is the clutch is now fully opened during deceleration and when the vehicle is stationary, which ZF says means it is now no longer necessary to “‘brake’ against the drive”. That is certainly how my 2015 MY feels when moving off from rest or when shuffling around whilst parking etc.

    It's been done to death.

    The only way you'll really tell is to stick it in D and then press the winter button. You'll feel the gear change even before you start moving. Go on, try it tomorrow... it's even more pronounced with a cold gear box.

    Everyone who has had this mentioned to them had either agreed, or just gone very quiet.

    The 8 speed does start in second, I'll give you that

    I understood the gearbox has some sort of memory and "learns" individual driving styles. Thus experiences of the gearbox can differ.

    Sorry, late to this discussion. Had both 6 speed and now the 8 speed. Not noticed any creep in either. However, the 8 speed idle is higher than on the 6 speed. In traffic, I tend to drop it down to 1st gear as it is easier to crawl in slow traffic. Idle looks to drop by 50-60rpm in 1st gear, compared to 2nd.

    And to add to the comments, I does not drop back to first gear when you pull up to a junction etc. If you want first, you must manually select it on the paddles. You can feel the change and the idle revs drop to show the change.

    It will drop into first if you boot it from standstill. But normally it stays in second.

    Hehe, didn't we agree to disagree on this last time? My 6 speeder definitely pulls away in 1st in most situations. Can tell by sound and feel but also when at a traffic light if I flick up to 2nd, can feel it change, paddle back to D can feel it change back.

    6 speeder? How quaint.

    All my XFs drop to 1st at standstill. If you think yours doesn't then try this.

    In D in non-sport let the brake go and then pull the right paddle. You can feel the car change gear and the display says '2'.
