I am in the process of rebuilding a 4r70w transmission and during the tear down I found one item missing from what I can tell from the 4r70w schematic. The two to three accumulator assembly was missing the snap ring. I have read from other forums that some have it and some do not. The schematic shows it. Can you please give me an answer on this one as to if its needed or not. Also was the snap ring on the two to three accum assemb part of the 4r70w failure as to your knowledge. Thanks in advance. If the snap ring is needed do you have a number or a link to purchase one?

Any transmission supply place should have it or a transmission shop for that matter. In picture is retainer or snap ring. If it was not there it would be awful hard to put valve body in proper position, but I am not a Ford specialist on transmissions and questions like this should be left to a transmission shop they will tell you one way or another. It may have been left out on purpose as well. Over time some things are not needed and tossed or just not put in. See picture.
