Cleaning valve body assembled?

[PaulRV6]

Instead of taking all the valves out of the valve body to clean it would I be able to submerge it in my solvent tank and then blow it dry? It sure would save allot of work not having to pull all the valves out.
The trans is being rebuilt but not because of a mass destruction.

That is the way my boss does it at work when he helps out with rebuilds. He soaks it in fresh solvent as the unit is being disassembled. After all other parts are cleaned and inspected, he goes back and hits all the passages with carb cleaner and then blows it dry. I rather disassemble and make sure there is no "putty" under the valves and hidden in the little nooks and cranny's. I have little nylon brushes that are long and between 3/8" and 1/5" and run them thru the bores with solvent and then clean with carb cleaner and blow dry.

Yea, that is what I am looking for. Need more responses before I decide on which way to clean. Thanks

If the trans. had a lot of junk in it I suggest as Eric said. Just lay everything out exactly the way it came out & you'll be fine.

Actually the trans was very clean, no debris anywhere, just black residue in with the fluid from the clutches.

Are you saying that if it was clean then I would not have a problem flushing the body assembled? Or is there still a concern for not getting the solvent out?

Thanks, paul

As long as the solvent is clean/unused before you start, I wouldn't be worried about that all not coming out compared to the little residue under the valves and in the aluminum sleeves where you can't just rinse it out. My boss doesn't like me to disassemble because it takes too long. I say you can never get it too clean. It may take an extra hour to remove and install all the valve train, but you will know it is clean and all valves move free with no burs or tight spots.

Paul, the best thing you could do is pull it apart, laying things out exactly as they come out in an organized fashion on a clean lint free shop towel. You will never be certain you have things all cleaned out unless you do pull it apart. I have seen things as small as a bristle off of an acid brush cause trouble with shifting in a valve body. That is just my opinion, but with major experience from working with Bruce.

thanks, Mark

I tend to bump things, and knock them about (I know, I know, no one else would ever be that clumsy...).

Even I have had luck keeping things straight when they are put down on/in corrugations. like one sided cardboard or such.

 

[PaulRV6]

Thanks for all your advice. I guess I will pull the valve body apart to clean, just to be safe. As long as I have gone through the entire transmission and feel good about how it has gone together so far, I might as well not scimp.

More questions coming folks. Thanks

Once clean & lightly oiled the valves should slide back & forth under their own wt. by tipping the VB side to side.
