First, im far from an expert, ,just my 02
Some ppl add a quart of tranny fluid,during a rebuild, pour it on the top, before installing the manifold,on a fresh zero miles engine.
ive never done it, but everones different.
Now if you got some miles on your engine/my opinion, id let it be,
Cleaning a used engine/ussually clogs the arteries{oilpump}because all the sheet goes to the oil pan.
Just use a good qual. oil,filter,and change 2000 to 3000mls,
i like castrol/ mobile 1 on a new rebuilt,

Most people leave it in for 500 miles. Some start with it and go the full 3K. Others use synthetics and don't bother with the atf, and still others use really good sythetics and are on extended oil change intervals. When Mobil came out the rags were touting 15-18K mile oil change intervals. Amsoil touts 25k/1 year intervals. Filter changes needed with both IIRC. Hell, BMW, benz and the european union are all on the extended oil change interval bandwagon now and GM's onboard oil analyzer has been showing that conventional oils and filters to be good to 6k in many cases. Though I'm not sure of the parameters in those set-ups.

well it was actually about a little over a pint of tranny fluid i poured in there, didnt want to add too much as it will end up makin the oil too thin. im jus tired of changin the oil n then 500 miles later its dark again...

Red Devil

Dark, alone, doesn't typically mean bad and one quart for the last 500 won't thin it out oo much... so long as you aren't raping the thing.

Maybe it's time to look into some synthetics, or Amsoil for some long OCIs. I know a cool independant dealer.

ya know, i barely beat on her, ill say tho, at least once a week i stretch thos legs

but i change the oil frequently as it is, and when i popped the intake off sludge was no where in sight but i was in the "ah what the hell" kind of moods so i added some tranny fluid for S & G

I have run trans fluid in the oil for about 15min before an oil change just to flush the engine, but thats it. Personally I wouldn't run atf in the oil for an extended amount of time, though it'll probably be fine.

Without knowing the miles on your engine,id refrane from any,attitives
cleaning a used engine,ends up with oil pressure problems, and bearing failure.
Just use good oil,at your changes.

Alot of old-timers have run trans fluid in motors for years at a time. One quart ATF, the rest normal oil.

I usually run it in a known dirty motor for only one or 2 normal oil change intervals, or until the used oil comes out halfway clean.

The first time you add it to a really gunked-up motor, change the oil SOON, like in 500 miles or so; it will loosen SO MUCH GUNK, you won't believe your eyes. The oil will come out thick and chunky sometimes. You don't want to run to very long like that, because goop like that doesn't flow or lubricate very well. So the first time you use it, check the oil often, and if it starts looking really funky, get it out of there ASAP. Then add it to the new oil and watch it again, and change it as it needs it. Keep doing that until it quits coming out nasty.

so buy cheaper oil while you are doing the tranny/conventional procedure till its cleaned out?

I would be hesitant about adding atf to the oil because it isn't rated to take the heat engine oil can handle. If you are getting dirty oil I would bet it is from outside contaminates, and not sludge. I would let that sleeping dog lye.

That.
