I had been planning on swapping in a ZF 5 speed into the truck for a long time, I even had the ZF and most of the piece's already. But after reading about TCI's Maximzer truck transmission rebuild kits and Hughes Performance's fuel miser towing torque converters I decided to stick with C6. So I sold the ZF which payed for most of the new C6 parts.
First thing I did was run down to AutoZone and pick up a Haynes manual for Ford auto transmissions, then I ordered the TCI kit and Hughes converter from Summit, while I was at it I also ordered a Lokar kickdown cable.

Started the other day with the daughter and I pulling the trans and pressure washing it.



I got feed up with the radius arm crossmember and cut it two to get it out.



Then I put the trans on the bench and followed the manual to disassemble it. It was actually pretty easy. There's a lot of pieces in there.




I made my own spring compressor out of scraps instead of paying for one.



Then I followed the directions and put it back together, got almost finished when I figured out that I left some wave plates in that I wasn't supposed to so had to take most of it back apart again. It's really pretty easy if you go step by step with the manual.
I got the trans back in the truck, buttoned everything up, started the truck and it actually moved forward and backward around the yard. I thought everthing was good so time for a test drive. We got just down the street and when it went to shift into second I lost all forword gears, but it still had reverse. Got it back in the yard and called TCI and the guy thought it sounded like a valvebody problem. So I pulled the valvebody today and was very happy to find a obvious problem. Check out the gasket.



The B&M shift improver kit that was in it before said not to use a gasket, but the TCI kit came with a gasket so I put it in, guess I shouldn't have. I cleaned everything up and put the valvebody back together without a gasket. Then it started pouring rain so I guess we'll have to wait till tomorrow to see if that fixed it. Everybody keep your fingers crossed for me.

looks like it should serve you well when done, c-6 is a good trans.

Put it back together and still no fwd gears, so pulled the trans again and opened it up. Found the fwd clutch hub broken.

Dang, I bet you'll know exactly how to rebuild that trans, that you'll never have to rebuild again. Sounds like the way I work. Once its done it'll be nearly indestructable, I've beaten on a tired C-6, like pulling 10,000 lbs at low speeds on a very hot day up some steep hills at full throttle with a 460 and it didnt make a peep. The engine, however made more than a peep.

Here's what the fwd clutch drum looked like.



You can see it took off the snap ring groove all the way around. I got a new drum from broader Performance for $25.
I cleaned the valve body really good and put it all pack together. Everything works fine now, line pressure is right on and it shifts good and firm.

Nothing like a little shrapnel to bogger things up.
Sounds like you got the parts for good prices (I'm used to pricing OEM tractor clutch parts) and all it cost you was a few days worth of blood sweat and tears (or beers )

Towed the Bronco a couple hundred miles to Gulches ORV park last weekend and the transmission worked great.
