'66 Aluminum Powerglide - Extra part???

[brungardtj]

Hello all. I'm rebuilding the aluminum automatic powerglide from our '66 C10 w/ 327 and have a question regarding a part we found. I've never worked on a tranny but felt like I could handle this rebuild. After taking it completely apart and replacing all the seals, I found this little mesh screen filter laying on the floor. I'm unsure where it fell out of and can't find anything online to know where to put it back before reassembly. I think it probably fell out of the valve body or possibly one of the pumps but I'd be grateful if someone could advise so I can finish putting it back together.

It is 1 3/4" long and about 3/16" thick. It is crimped shut on one end and the other end has a brass ring for structural support. Any help would be greatly appreciated.

The only thing I can think of "like" that is a fuel sock: https://www.opgi.com/chevelle/CH28637/
GM had a Powerglide from 58-62 with a different screen on it below, but other than that I don't know.

That is a screen for a oil passage. 350s, 400s and 700s used them for a governor screen, (now made of plastic) under the vavlebody in a hole or passage in the case. But I have to admit it has been a long time since I've worked on powerglide. Can't remember exactly where they go in one.

That's great information and will be helpful. Do you know if it's required? I had an experienced tranny guy tell me not to worry about it if I can't figure out where it goes. He said it was redundant but I'd really like to put it back in though. If anyone knows where this goes or has a picture or drawing, I'd really appreciate any help. Thanks again for your responses.

you should be able to find it on a parts blowup of the trans

If you look at page #43 of the Powerglide transmission Book by Carl Munroe there is a view of the bottom of the transmission. There are two ports under the valve body one is the pressure port #11 and one is the suction port #12. I have the brass ring with out the mesh, it fell out of port #11. I talked to several transmission repair mechanics and they are not familiar with the part. I do know that I have disassembled 3 powerglides and only 1 had that brass ring w/mesh.

It will not hurt anything without it.

Thanks everyone for the input. It appears the general consensus from this site, other blogs, and tranny shops is that it really isn't necessary. The picture in the book isn't the same as the valve body that came out of my tranny thus I was unable to find an applicable hole to put the screen in. I'll probably just leave mine out. Thanks again.
