I don't think that I can paste my link, because it's full of auto-login PHP sessionID stuff. The "After 1-2 seconds...." paragraph is completely mine, he didn't talk about the lock-up process at all. The original version also talks only about shifting between OD and 4th, but the advice is applicable to shifting 4th-3rd as well.
(And maybe 3rd-2nd too. I haven't been on a steep enough grade to ever take a good look at whether there's lock-up in second. But I'll SWAG that there probably *IS*, even without invoking the special off-road gearing and differential lock features of my "Sport" model.)
Yeah, I'm not a writer, the two GOOD paragraphs are not by me.
