In any case, transfer gears are pretty necessary in manuals too, so it's no real surprise they make an equally huge difference to an auto car.
Steve.
I'll take that to mean that "
low reduction gears in the transfer for a Manual too", and that is so in a Sierra because of the relatively high Gearbox and Diff ratios. They would not be
quite so necessary if the gearbox and diff ratios were lower. This is the point I was getting to about the 1st gear ratios available in Auto boxes. As an example, one of my other (manual) vehicles has a 6.40 1st gear and 7.16 diffs, and performs superbly off-road with only a 1.87: low range in the transfer. Low transfer gears are not necessary in that case. Another example of a brillant off-road performer is the Haflinger, which has no low range at all, but does have an ultra-low 1st gear.
If Autos came out with lower 1st gears (and with 5 speed Autos becoming more commonplace, why not?) they would find more ready acceptance in the real 4wd world (ie not the "Mum's Taxi" market). It's true that some people have great experiences with Autos off-road, but only after they have done something to take the high gear ratios into account.
