Answer
4cyl?
6 cyl?
My Dad used the old ATF in the oil trick. It never proved to be a problem, as long as you get ALL the fluid out.
He ran a quart in it for a day trip to work (10 miles one way)
Then would drain it for a half hour.

If the Atf is left in there you run the risk of it softening a seal and getting an oil leak.I never ran into that.
