If I was still running an auto it's what I did. I was always the first to grab 4low out of the group. Mostly for the fact that the ratio made up for my lack of low end torque and less than ideal tire size and axle ratio.Having had both an manual and an automatic, I would offer this on the automatic.
-- For crawling, get into low range earlier than you would with a manual. There is no penalty for this as you rarely use the upper gears in lower range - now you can.
-- Some modern auto transmissions have a "sports" or similar setting. On our Isuzu, the sports mode was perfect for rolling mounting roads in the Andes. It kept the transmission from upshifting at the top of a grade, just before you began a descent. Also held in the lower gears a bit longer, useful for performance at altitude.
Offer with the usual guarantee for free advice - the price is right.
With the big block and granny gear I don't expect a need to go to 4 low as soon as I did in the past. We will see. I've not had it on anything more than a dirt road since the swap was done. I get to relearn how to drive off road with a stick again.
