    Using the ZF in the hills

    More used to flat roads in Suffolk, travelling the hills in North Devon, as usual left the ZF in D to decide for itself, but noticed it was usually a gear higher than ideal and relied a lot on the engine torque around 2k revs which tended to be, well not brisk and also hit the fuel use. Towards end I started manually selecting which seemed happier but more work.

    I used to manually select 2 with old BW, mainly as tended to drop into higher gear when easing off around hairpin bend and then struggled afterwards but the 4spd is more flexible.

    Just curious, what do others do in hilly areas? Also wondered whether I should tighten kickdown to make more responsive?

    I tend to leave the ZF box to decide. We live in Dorset and drive around the Purbecks which involve driving some steep roads in some parts. MPG if that is the only area I am driving around is about 20+ mpg. Before it was between 17 to 20 (at best) when I had the BW65 box. Now on a mixed drive down lanes and some dual carriageway driving, the mpg is around 27. I hope it will be nearer 30 mpg on a proper long run.

    My delayed drive across the Alpine passes may result in getting my Stag specialist to “tweak” when the box changes up and down. Clive Tate set it for touring rather than performance! It’s my age

      If driving around hilly lanes I will often put it in 3. This seems to liven up the changes and makes for a better drive. Doing this quite a bit here on the IoW, except when cruising the Military Road as we have been today

        +1, I spoke to Russell Lewis at the Nec or somewhere and he said you can tighten the kick down a bit , BUT the changes will get more like a BW (Harsher). I took a while to get use to the new box as the car was not as lively, but as Dave has said I started using 3 which makes it better.

          Thanks fo all replies, mixture of both. I love the ZF and had it for around 10yrs but this time just felt a bit lifeless, I mean Porlock hill in 2nd/3rd?. if it had been a manual I'd have selected a lower gear most of the time, it was only towards the end I thought try manual selection instead. I'll try as DJT and MandM say and leave it in a lower gear next time I'm there.

          Cheers

            Haha - I know the feeling. The box is far better for economy - I used to get 200ish per tank on old BW but now its nearer 250 and saw 300 on occasions. Good luck abroad

              Interesting that is could become harsher, I'll play around with kickdown and see the affect. Guess this is why modern cars have selectable performance modes....

                On hills I use mine more like a manual ‘box, changing as I feel necessary. On my recent 1000 mile tour of the Yorkshire hilly areas the gearshift on my ZF rarely stayed in D. On the recent attack at Prescott hill-climb I made it from start to finish in 2nd. However, when I’ve toured France and Germany I usually select D and leave it there for the autobahn.

                  Guess I've just got used to leaving it in D, on the flat its fine. I did wonder if it should be more responsive (by adjusting kickdown) or leave as is and manually select.
