As Don Says... drain 1 quart out and add one quart automatic transmission fluid. It will also free stuck lifters. drive it for 10 to 20 miles then drain it, add new filter and oil. whatever residue left will not hurt the engine. Change oil and filter again in less than 4K. Don’t forget the air filter too.
ATF is basically 5W20 base oil with LESS detergents than motor oil but with friction modifiers for the clutches.
How that high detergent myth got going I’ll never know.
Engines see products of combustion (that get past the rings) but transmissions don’t.
