Can someone ID this part for me?
I am overhauling a 700R4 with a total rebuild kit from probuilt and I have two questions...
1) Can someone identify this piece for me? It's in the very tail of the transmission and popped off while I was removing the shaft from the tail. It looks to be some kind of retainer clip. It happened at the same time in both trannys during disassembly so right now I am really confused.
2) Can someone direct me in the proper removal of this circular piece here in the back? It's the last thing left in the transmission housing and it has a number of springs inside of it. I think that we have tried almost everything to get it off, but there has to be something that we're missing.
Just for kicks, I've included some other pictures of the project. I gutted both the transmissions that you see on the table. One is out of a v6 and the other is out of a v8. I gutted the v6 for some small parts.
In this picture you can see the v6 tranny on the left bench and the v8 tranny on the right. Both casings are obviuosly sitting right in front on that table.
This is the valvebody off the v6.
A better picture of my workspace.
The (almost) totally cleaned out casings.

In the second picture where you see into the case and there are the slots where the steel plates go into, that goes in there beween the case wall and the set of steel and friction disc and it's held in place by the grooves, I forgot where or how it goes, but that might help you, probuilt should be able to help you on that or if you have a diagram it'll show you exactly.

I think its the lo and reverse clutch spring assembly, and you need a special tool to remove it. Thats what its called in my ATSG manual. My friend Floorguy has the tool to remove it. It applies pressure on the flat part with the holes. I dont know what the tool is called, but it clamps to the notches on the insides of your case, and you adjust it so it puts pressure on it, so you can remove the retaining ring that is holding it on. If you do a search on this site, I have seen someone using his own homade version, with some steel rebar, and some eyelet hooks bolted to the dowl pin holes of the trans.

Thanks for the thread, I've gotten a lot of good information out of it.
I'm still looking for the location for that clip though. I think that I might go crazy if I don't figure it out soon.

Off the top of my head thats the anti-clunk spring for the low/reverse clutchpack. At the very back next to the apply piston there is a contour between the lugs that the spring fits into.
Nows a good time to buy a manual before you assemble the trans. I found that both the haynes and the ATSG manual work well. Lots of pics in the haynes manual with all the info in the other one.

As for number two, I found that a piece of PVC piping, two sections of square steel stock, and some threaded rod work well for compressing the low/reverse piston spring. I can post a pic of it if you want.

Heres what I used to compress teh low/rev. spring. Be careful compressing it. The retainer is just thin sheet metal and can bend real easy. The piece of pvc pipe spreads teh load around the retainer. The rod passes in from the rear of the case and the shorter section of steel rests on the pvc pipe. Tighten the threaded rod and it compresses teh spring. The plasic there is to protect teh bushing at the rear of teh case.

You might have to use some compressed air to force the piston out. Make sure you have the case facing down so you don't shoot it across the room.

I'm going to try to remove it tonight.
If it's that compressed inside the casing... how hard is it to reinstall using the same tool?

The spring is easy to remove and install. The piston will need some compressed air to get it out. Installing the piston was a different matter. It was a real pita to get in with the new seal. I used that tool to carefully draw the piston in and I let it sit for a while to give the seal some time to relax and allow the piston to freely move.
