I purchased my rebuild kit for my e4od from Sonnax, really liked the quality of the parts. Updated from aluminum to steel parts and it was awesome with the TransGo tugger shift kit

Pan and vale bodies removed:
Got the pump out with a slide hammer:
I removed the coast clutch drum and found damage. Upon further inspection it looks like my over drive snap ring popped out and caused the over drive clutch piston return spring to come loose. I think by that happening it caused the friction and steele teeth to eat up the coast clutch drum. Apparently this is a common problem on the 4R100 and I'm lucky I caught it before it did a lot more damage.
Damaged coast carrier drum:
The o/d snap ring that failed. You can see the damage on it as well:
I find it easier to line up tables and set everything in order.
So now it's back to finding parts to replace the damage and an updated o/d snap ring so it doesn't pop out again.

500 pounds is probably a little high, but not much. I'm not certain what a transfer case weighs. I'd guess around 150 pounds. The transmission weighs 270 pounds.
