That shifts between low and high range automatically? I don't see the necessity, usually a quick operstion

something powerglide based that would shift on the fly under power would shave some time and be bombproof but probably not worth the weight and driveline length since a transfer case gear or chain drive would still be needed. Would be the size of a 203 or more.

Engineering is a beautiful thing.

tap auto trans's line pressure with a solenoid to flow or release the pressure to the range box. most likely use planetary gear set out of automatic transmission, then use piston and such, and more?

I think this is where the new 6L80, 6L90, the newer 6 speed GM auto trans come in picture, no fancy range box or doubler needed.

6L80 is used in 1/2 ton GM trucks and some cars, so they're going to be plentiful

first gear is 4.027 with double over drive, 0.852 (5th) 0.667 (6th)

compared to the ancient 3 speed TH400 with first gear at 2.48, third gear (direct) at 1:1.

Novak shows 6L80 to be shorter than TH400, even.

They're relatively bulletproof in stock form IIRC.  8)

Pleasantly surprised with that weight after it weighed in at 4900 a few years ago.

4.3 Atlas worked great. Front output is now closer to front axle and higher, front driveshaft double cardan not happy even after some grinding for clearance. Ordered fancy Tom Woods offset u joint to run at case front output with single joint shaft. They claim 45* with yoke grinding.

Had issue stalling and backfiring out intake under medium and heavy load at low RPM twice in a row running Gauntlet backwards. Weak fuel pump? MAP sensor or something else that helps engine react to load?

Gauge cluster dead this winter after sitting in trailer for 3 months. Going to try cleaning terminals and reinstall, if no change it's getting my old cheap tablet and wireless OBD reader like Mark and Dennis run.

Got new rear shackle boxes and frame section, some new driveshafts, windshield pulled, cooler stack, fan and shroud, headed panel mounted to fender tube after roll smooshed stock rad support.

Ready for another season of abuse!

Suckdown winch setup. Need a better way to double strap on itself other than the bolts I’m thinking.

Only real upgrade on the list for this winter. Dozen or so maintenance items and it’s ready for another year of abuse.

I think I have decided a Unimog portal axle moon buggy is the next big move. This hawg is slated for a few more years of fun though.

Hoping to make things like this a bit more stable.

Still can’t believe I thought committing to that climb was a good idea.

Indeed!

Pipe/tube with a couple bearings, full of grease in vain attempt to not have it seize up?
