ATF in Engine to clean it???

[Richard Hoffman]

I heard report of a lister attempting this method of engine cleaning and
IIRC he had an engine that leaked like a sieve afterwards, requiring sale
replacement EVERYWHERE.  I wouldn't recommend ATF in the engine.  Even
switching from dino to synth can do a significant amount of cleaning....
