need help Guys I did the yearly dumbass award for 2013.
So the warden dissapears for a while and I have the brilliant idea to take the top rack out of the dishwasher and throw the empty transmission case in there to clean it thoroughly. No soap/detergent.
So 80 minutes later... I open up the dishwasher and much to my surprize I have a transmission case that is not what I wanted to see.
I pretty much oxidized all the machined surfaces. Due to the water softener I would imagine.
Any ideas what to do to fix my f up. I can't add pictures from my phone I guys I will try to post later

NAPA sells a product called Aluminum Brightener. It will remove that oxidation. It may however turn the surfaces black/grey in color. Depends on the alloy used in the trans case.
Relatively cheap to try.
BTW.....I once put a set of iron rat motor heads in the DW......rusted the crap out of them!. Boy did I feel like an idiot........

Wow, that really does not look good; I don't think the gaskets would seal without sanding and the residual mess might run other parts after assembly.
You might want to search your local Craigslist for a cheap "blown" trans (about $100), get a case from a local rebuilder or find one on ebay.
I have bought several large parts from ebay seller "powertrainpartsplus". They sell empty, clean cases for $69 plus $24 shipping. This link might work for a while:

Perhaps someone else has a good and safe method of cleaning this up.

I am still kicking myself over this one.
Thanks Mrvedit. I may just grab one of those cases if I cant find a way to clean this up.
I had thought about electrolysis but that only has really good success on ferrous "magnetic" metals, I hope someone else chimes in with an Idea on how to clean this son of a gun.
I cant believe I didnt think of the salt from the water softer.

Maybe you can try some brake parts cleaner, they have a higher pressure spray.
I would inspect a couple of areas closely. There is a checkball at the rear of the case to make sure it looks like it will seat.
The other very ctitical area is the 3rd accumulator checkball. You can see this from the servo area. It will need to be checked to make sure there is no leakage into the case by pouring fluid into the passage on top of the ball. You should only see fluid leaking into servo area.
Any fluid in the inside of case is bad and the capsule will need to be replaced.
Also,
You could maybe check an engine or trans shop and have the case hot tanked..

For all the rest of the replies thank u as well. It appears that standard distilled house hold vinegar is doing the trick. I will update with pics later on. Also I will hit the valve body area with a flat board and fine grit sand paper or a stone to get the very small pitting that occured. I may need to replace the check *****.
But the damage appears minimal so far.

Having a local shop hot tank it for you after you finish sanding and cleaning is an excellent idea; it will also remove most of the sanding dust. My local trans shop has a hot water washer that does a good job in just 10 minutes and minimal cost.
