Georg, good stuff. I imagine in 2 years you may be doing NWF installs instead of 3.1:1 gears.

The taco pic above is 2.28/4.696/5.29/a340... I never used ultimate low, but 2.28 was absolutely insufficient for creeping thru wh1@ fordyce and the rock garden @ Barrett lake.

Everyone who's gone from minitrucks to 80s has a completely different perspective on gearing. And when you try stuffing a gigantic station wagon down tre lined ravines and rock gardens, there is no better preservation of glass/ sheet metal than super slow.

FWIW, there is no shifting to neutral because you can idle in super low thru the brakes. I don't know where that presumption became repeatable fact? But I heard it often during the build of that truck but never experienced it. And that truck 'creeped' everywhere. Granted, my trucks always have brand new brake components and aren't cobbled together as a trail rig.

Wife and three kids, or my buddies and our kids. Packed that camper shell full of more random BS to camp w 5 people... That truck rivaled an 80 in weight no doubt... It even had a microwave.

Marlin has described the possibility of >3.1:1 gears for our tcases(4:1 is completely possible in the confines of the h2av) but it required enough grinding and stuff that it wasn't marketable to the 'normal' 80 customer who bolts on an ARB bumper and J springs w 315/75s..........

You catch my story.

This isn't for the mainstream 80 crowd. But the mainstream 80 crowd is changing....

Prefect for that tire size if you ask me. And would work great with 37s also.

It isn't. Especially down hill in an auto. Again, perspective, spoiled from crawling in dual cases in minitrucks.

I see no reason why I wouldn't be installing the NWF doubler AS WELL AS the Marlin gears in the future. They both have their place.
Your taco is still very different than an 80. The torque curve on both engines are very different so they will behave very different.

What I posted is far from presumption ............... I've been wheeling at rubicon since 1988. Obviously I've run plenty of other trails as well. And I've done so in multiple rigs; two of them were mini trucks. The later one of the 2 was a DD 85 4-runner ON 37s with a vortec 4.3, 4L60E and double cases with low gears in one of them. Double low was too low. It was useless. And even though I had anticipated the possible issue of "crawling thru the brakes" ( experienced in a previous vehicle ) and tried to avoid it by going with a slightly higher stall converter, it was still a problem. The runner had more than adequate braking and I could stop it, but at that point it was pretty much fighting itself.

Personally, I'd rather have a shorter gear train and less spline slop so I prefer single low geared t-cases. In a perfect world, that should work great. And it does, if you only run one type of trail. But if you're using your rig for different offroad applications ( trails, sand dunes, rocks ) then a lot if the time a single case behind an auto just doesn't offer the "proper" gear ratios we're looking for. So the doubler becomes a necessary evil. It's not that we would usually need double-low behind an auto, but we need the gearing choices offered by either a stock low-range or something lower. For the 80s, you probably will have to run double-low on some of the tougher obstacles since there isn't a single "low" ( 4:1 or lower ) gearing option.
All of this pertains to cruisers with autos. I'm not talking about mini trucks or other vehicles here; trying to stay on subject.

For most owners, a single low geared t-case along with lower axle gears will suffice. And as long as you're running a good transmission cooler you won't hurt anything. A good spotter goes without say.

But for some guys, lower gearing is absolutely needed. And that's where the NWF black box will shine. I'm certainly looking forward to seeing yours Paul!

thx for that george, max I will go is 35's to minimize drivetrain breakage problems, makes me want that even more! soon, soon.......

you mentioned a good transmission cooler when installing the marlin gears? does this increase heat considerably in the transmission where the OEM stock 80 tranny cooler becomes not efficient enough? is there a tranny cooler you reccomend that you have installed?

A larger than stock secondary/auxiliary transmission cooler should be on anybody's "to do list" who's going to wheel any vehicle with an automatic. This becomes even more important when playing in the rocks.
The torque converter is where 80-90% of the heat is being generated in an automatic transmission. That's due to slippage. This is amplified when you're dealing at low speeds. Keeping the temp down is essential to ensure proper transmission function and life expectancy.
I prefer the "stacked plate" coolers. They're manufactured by Long and can be found at summit under the "B&M" brand and others. Cooler flow should be: transmission to primary cooler ( stock unit in the radiator ) then auxiliary cooler and back to the trans.

Hth

Georg @ Valley Hybrids

Ps: one of the added benefits of ultra-low gearing is the amount of "work" the torque converter has to do is drastically reduced. And the trans will run cooler.

Georg are you saying to replace the existing cooler mounted in front of the A/C condenser or adding an additional cooler? So you would have 3 total? I almost kind of feel like a petcock or diverter valve on the path through the radiator for summer months might not be a bad idea.
 
I should have clarified ....... I would remove the factory secondary unit and replace it with something with more cooling capacity.

And if you want to go all the way; install a trans temp gauge.

Booger Weldz did you get a trans/tcase to nwf? Kris was asking if I could send him one as of Friday.

Yup. This is important to understand for 99% of 80 series Land Cruiser owners.

Low gears in xfer and 5.29's here on 35s and this setup was awesome on the Dusy--it was almost too low.

Out East now, it is almost way too low on everything I do and I pop it into N pretty frequently to keep control of the truck as Georg described.

That said, after 12 years of 80 series ownership, I have also learned how to drive this 3 ton brick quite well. :)

This "black box" will be interesting based on what needs to be done to install it behind an auto box like the A343F.... The gas tank is still my area of interest in that 7-8" is going to add a lot to an already long drivetrain.

Looking forward to seeing progress.
 
My threads in 'hauling' pirate and 'mudship' here have gotten no hits that bear fruit. I had a lot of PMs from people going north for the holidays, but nothing's ever happened. Lotta flakey, frustrating stuff...

There's a couple reliable guys who can deliver it, but that route(up to pnw from central/northern CA) is not in their immediate logistical plans.

Anyone reading this that won't waste my time, please PM me... I don't wanna hear about your sister in laws uncles dogs veterinarian who's brother drives a big rig though. <----frustrating....

It's all here on a good pallet ready to go. Has been for quite awhile and I'm sure kris/Kyle is 'wtfing'....

I'm about to move so it will goto storage if I can't get any hits on the hauling threads here and on pirate ASAP. the tranny will be returned to it's owner....

Sorry, I've shipped a lot of stuff in the past using those resources. Kinda dry currently for some reason.

Did you try Odie aka "megatoy66"?! He's transported plenty of stuff for me and he's ultra reliable.

If not, maybe Tor up in Seattle has a combo they can use for mock-up.

Do you know what it would cost to ship that? I'd be willing to pitch in to help get this moving. I'm sure a few other guys would too.

Truck freight is generally reasonable.. Maybe $100 - $150 I'd doubt if it would be north of $200.
 
I sounds like a pain to split up travel, but I will get it across Oregon from northern California to southern Washington if it would help complete the puzzle. Both ways.
 
I just got in touch with Adam at Torfab in Seattle.
They have a complete setup. They're willing to let the guys at NWF use it for mock- up.
They're heading to Vancouver in a couple of weeks. Could bring the combo with them and drop it off.

Done deal.

Next!
