So I had to pull my crazy heavy trailer the other day and my normal puller, a '99 f-350SD, was out of commission waiting on some parts. So I figured I just hook up the ol' Yota and away I go.



As I said the trailer is a little heavy so I needed the low grunt of low range. Well wind up Lo 1-5, grab Hi and 3rd, 4th, then 5th. Who knew it was an 8 speed?

How'd you change between lo gear and high while moving without killing your transfer case?

lol its easy, pull the lever down.

been doing it for years, just grinds a lil bit, nothing major.

you can go from low to high with out much trouble, just cant go from high to low

You can double (or triple) clutch to shift from low to high range. I do that from time to time, like in heavy stop-n-go traffic, low range makes it easier to creep along, but if all of a sudden traffic opens up and you are doing 30 or so, you can go up to high range by picking the closest gear there and rev matching before shifting the t-case. And you can go into low range on the move, but it takes a much more precise shift to get the revs right (t-case is non-synchromesh).

Let's just say the eyes on the flagger at the construction site I had to drive passed were as big as dinner plates when he heard me pull out, shifting through 4 gears up to about 22mph.

And 4crawler is right , it all comes down to matching speeds, wound up 5Lo puts me just ahead of 3Hi. Get 5Lo, push clutch in, shift t-case to neutral, dump clutch, push clutch in and tach up, grab 3rd gear, dump clutch, push clutch in and tach up while pulling t-case lever to get Hi-Range, let the clutch out. It seems like a lot of work but to a guy that doubles in everything you really don't notice.

Very cool. Will have to try that sometime! I think I have a spare transfer case if my timing is off...

fierohink

Works best when you are really overloaded otherwise you wind up and down too quickly.

Huh, never tried that. I'm very good at rev matching (and decent w/ heel/toe)- I'ma give it a whirl sometime soon.

geez, now you're going to me ME try this too, lol


might try to tow my father's boat or something

i shift from 4 lo to 2 hi all the time.... i find that 4lo 3rd matches 2 hi 1st... i'll get to 3rd in 4lo, then shift to 2nd, and throw it into 2hi all at the same time.

Just tried it this morning - works great! The t-case was a touch notchy going from Lo to Hi but that's just because I'm a n00b

with both my 4runner and my truck, i necer stop going from 4low to 4 hi. just push the clutch in and shift it as normal. but i always stop to go from 4hi to 4lo

Cool, never thought of doing that.

Neato. Gotta try that one.
I like using 4lo in traffic. Just idle along while everyone else with slushboxes drag their brakes.

iamsuperbleeder

I was going to try this out today...


but I ended up not taking the ol girl to work... it was too cold to drive 40 minutes without a heater, lmao

I've had to do that kind of thing a couple of times pulling heavy trailers but usually just to get it rolling. The 4lo is great to use to get moving on icy roads/parking lots sometimes because it keeps the driveline turning slow enough the wheels don't break loose. A lot of fun but too much like work for an everyday thing.

mmcpeck

I use the 4Lo to get my boat up the ramp, creeps it up nice and easy with no beating on the clutch, I usually stop once up the ramp and switch back to 2Hi, but never thought of doing it while moving.

Might be stepping up to a 25' boat this winter, and was wondering how the hell I was going to trailer it with my 3.slow, not far, just a couple miles. Looks like this may be something to try.

So I can get some momentum with 4Lo and just pull it back into 4Hi once I get up to like 15-20mph, or to 2Hi?

Is there any gear reduction from 2Hi to 4Hi?

the 38 special

no, its 1:1, just engages or disengages the front prop shaft
