C4 what am I missing here?

[Itsa67]

I just got what appears to be a great deal on a Bronco C4. It came to me mostly complete including the adapter housing. I know it is missing the spud shaft but it looks like I may need to scrounge a bit more. Can anyone tell me from this picture of the adapter housing what it might be missing. (Maybe all there??). Thanks!

More pics of my new to me transmission.

So, I am basically trying to figure out the minimum amount of things needed to get this installed into my Bronco. It came with what appears to be a rebuilt torque converter. Since I'll be swapping from a manual I know that I need to remove the bushing from the crank, purchase a 28oz imbalance flexplate and add a transmission cooler.

Any ideas on the adapter area in the first picture? This thing literally pored out bright red transmission fluid when we were loading it up. I am guessing that I am missing a bushing and some sort of seals at the minimum. Still pretty happy with my $100 purchase!

If you go to this link, look at what is there, then scroll down a bit and open the installation guide and take a look. I've never done one, but from looking at the pics, it looks to me like you are missing the bearing retainer for the spud shaft, and associated seals and clips and gaskets. And you already mentioned the spud shaft.

Thanks for the link! At least I have an idea of what I need to be on the lookout for.

You're missing the bearing, bearing retainer, spud shaft, and input gear. The assembly often sticks with the transfer case when separated from the transmission and less than knowledgeable people don't realize the assembly goes with the transmission so they leave it with the t-case.

Here's a photo of the assembly

I'm pretty sure that is exactly what happened. The guy I bought the transmission from had a bunch of stuff for sale. I hit him up this morning but the transfer case is already gone...oh well-win some, lose some.

Thanks, Justin. I've not been inside that part, so I was just going by what I saw on the WH website to get him started.

If you're interested in buying the assembly I have, let me know.

As a follow up to this post. I really lucked out and found what I needed. Seller had a dana 20 for sale and I noticed the bearing retainer hanging out of it in his pictures. Anyways, had to buy the whole J-shift but got what I needed plus the J-shift front output, which is supposed to be an upgrade for my original T-shift transfer case. Another $100 spent but I feel pretty damn lucky to score a good C4 setup from torque converter to transfer case for $200 bucks. Just need to come up with a flexplate and block separator and I'm in business! Anyways, thanks for all the advise on what I needed to look for.

At least the flexplates and the block plates are available new.
Now the Issue you might run into is, does your existing torque converter have the small bolt pattern or the big bolt pattern.
I may have this backwards, but I think I am correct in saying that you can buy both types of converters new, but nobody sells a flexplate with the small pattern anymore.
You would have to find a used one.

Someone here will know the exact specifications on the bolt pattern. Have you measured yours yet?

 

[Itsa67]

The torque converter is a rebuilt, painted green and has sharpie markings of F48 with a 2005 date. Looks to be the big pattern, so I think I'm in luck. I was planning to order the flexplate etc. from you guys. Thanks!

Bolt circle is easy to check, It is either 10.5" or 11.4"

 

[Itsa67]

Yep, it is the wide pattern. Now to find a block plate and inspection cover. Anyone know which ones interchange with the big bell C4?
