Add transmission fluid to engine oil?

[mr_miles]

I would occasionally run a quart of ATF down the carburetor of my RX7 to loosen any gunk up in the housings and such. it worked. I would blow carbon out of the exhaust after about a half quart lol. also ran it in my scout II for a bit, helped there also. on a newer car i dont see the issue - if you're worried about the classic toyota sluge issue which can still happen on our 1nz's (or at least in my buddy's ill maintained xb lol) i dont see it being an issue. run a quart in there for a very calm and smooth few miles and it'd probly help clear any goo up.

that's my 2cents, I say go for it. I'd try atf before seafoam - I am scared of that stuff. I've seen it destroy just as many engines as it's saved.
