    That high 5th gear high ratio on our 2002, 2.8 JTD has never really been a concern to me, if I get that long old climb on a motorway I just drop down to 4th and keep to about 50mph until I'm over the other side. But, we're thinking of getting a Smart car and trailer and I'm wondering if that high ratio 5th might not cope with the extra load.

    I believe it's possible to get the ratio changed easily enough if need be.

    What do we think?

    The difference between them is about 400 rpm @ 60MPH, so highest about 2000 rpm & lowest is about 2800rpm.
    High(53x31)=1.7-1, medium (51x33)= 1.54-1, low (45x33)=1.36-1.
    I have a pairof the 45x33(low) if anybody wants some.

    That is very useful, thanks.
    I wouldn't mind betting the medium would be good for me when towing, won't really know though until I give it a go!

    I had my engine remapped and I can happily tow in top now, before I used have to come down one for the revs
