Sigh.....I just told you. IF you broke the gears the chunks may ocassionally bind up.

My Bad, from the way i read it, "every once in a while they get in the way of eachother, lock up, and you momentarily have drive again" made it sound like the chunks getting in the way give me drive. The differential is very confusing to me. I just dont understand how it can slip like a clutch, youd think if you broke the gears, your car wouldn't move at all, instead of slowly moving up to speed. Lol i dont mean to make this difficult, but the transmission and differential has been a couple things i haven't went into depth with.

Mine did the same exact thing besides popping out of gear. Turned out to be a bad tcase

power just isnt being transfered to the front either. None of the wheels are getting the full engine load. My tcase is good, gears, bearings, and fluids are good.

Even when you rev it really high in gear?

I can drive it, but i have to drive at very light thottle for the car to go, because anymore that 10% throttle and it starts slipping. Every once in a while the car will jerk really hard and ill feel the cars actual power then itll go away and slip again. Also for some reason Reverse feels like it should.

The center differential allows the engine to drive the rear wheels. It splits the power when working correctly. Weld the center differential, and you have 50/50 split to the front AND the rear. Now break the center differential and you have just the front wheels with power going through an open front differential with a lot of wasted energy spinning a viscous coupler that's trying to get energy to the rear wheels. That's why it feels like it's slipping, because the vc is slipping, probably overheating and when the chunks all bind up, it hits. You're probably grinding all those chunks up in a blender and trashing your shaft bearings, front differential bearings, spider gears, sliders, and everything else that moves in the transmission.
Drain the fluid and report back.

Check the splines on the tcase and output shafts also. Less likely since it catches but another possibility.

WELL that solves it

Drain your oil to verify. It will be obvious if there's an internal component failure.

No, i posted a picture haha. I have the diffs swapped.
Total annihilation.

I'm sure the transmission is full of metal. Bummer.
But, you found the problem! Good job!

I tried to tell you......

Time for a rebuild, sorry to hear that good news is build better now since your there, just got a fresh rebuild on mine.

Checked all gears, they're unscaved, the only metal was the huge chunks of the spider gears inside the diff housing, and there was one chunk that got out and fell down by the drain plug which i removed. There all the holes on the housing were blocked by big chunks. Only one managed to get out. Everything is good, bearings are good. Im going to flush it out though. Only other metal is the fine metal shavings thats common in trans that dont have oil changes alot. But other than that, the transmission is clean and unmarked.
