What to use to clean inside of transmission?

[yolner]

I want to clean out the crap on the bottom of the trans while I have the top cover off. What's safe to spray in there? I was thinking brake cleaner, but wanted to ask the experts first.

I don't see why brake kleen wouldn't work. The only concern I would have is if spraying from the cans might blow any fine metal particles around in the case and find it's way into any bearings. Maybe as a alternative you could wash it out with diesel fuel in a garden sprayer that isn't as powerful a stream.

Diesel right?

 

[DieselBob]

It doesn't clean all that bad and unlike brake kleen, gas and some other cleaners it leaves a oily film so metal like bearings and shafts won't flash rust. Although the price per gallon is getting into the cleaner price range.

Thanks for the info. I'll probably use both. Brake cleaner for the bottom gunk and diesel for everything else.

I would use diesel, put in a low pressure air line, 5-10 psi to aggitate it, put in a few magnets to collect any metal findings, drain, flush and remove magnets.

I've done several with brake cleaner.

Diesel will work fine !!! Fumes not as harmful and flamable as Brake Kleen in a confined space . Your choice be safe and don't mke your deuce giant smores roaster for the kids !!!
