Anyone ever clean a 722.3 trannie valve body?Any suggestions on DIY guides

In interest to the 617 and the trannies that keeping them chugging down the open roads I would like to build an interest on how to DIY everything on these transmissions up to a point.Im right at the moment looking to open up a bench unit 722.3 and use it as my own personal tutorial on its gaining a new life possible without a full rebuild.The Parts or kits that Ill be looking to install new are the k1 ,k2 springs,b2 piston ,clean valve body ,replace seals and gaskets,vacuum modulater, bowden cable , filter and fluid and to test pressure and setup of shifting . Any add ons that should be considered?This project I might give to my Indie Mechanic and take pics during the freshening up , a list for his approval, an advisory overview for those willing to tackle this as DIY thena follow chart with dos and donts.The real issue after all is that these trannies are subject to vacuum controlled functions and over time they will need to be addressed .The purpose Im suggesting is a quick look at the whole subject of trannie performance and the items to gain its orig. ability .

First, look for the detailed post w/ photos of a tranny rebuild. Re valve body, I haven't heard of a need to clean it, but not the expert. At least in the other trannys I rebuilt (Chrysler), the fluid was pristine inside, as was the valve body. I only opened the valve bodies to perform a "shift kit" upgrade. If you do open one, take photos first before any balls move. The balls can be different sizes and some are not installed in certain models, and your documentation may not tell you what you were supposed to have. At least I recall that was true in Chrysler world.

Sub'ed! Assuming the 722.4 is similar enough...

I did this partially when I installed the Superior shift kit.



The key part is not losing any pieces, and putting everything back in the correct place. There is minimal documentation on how the valve body should go back together. Take pictures!!! Take notes! I'd also suggest working on only one cover plate at a time.
