Can you use automatic transmission fluid for motor oil?

In most cases, adding ATF to motor oil reduces cleaning power. Instead, ATFs have elevated levels of friction modifiers and other additives that help protect gears and clutches. Second, ATF can disrupt the engine oil formulation and reduce its effectiveness.

What happens if you put engine oil in ATF?

Using pure motor oil would certainly result in transmission failure very quickly as the clutches and bands would slip and wear out (and also cause extreme amounts of heat in the process, coking up the oil and likely damaging many other components too) but a small amount won’t throw off the friction modifier content of …

What can I use instead of automatic transmission fluid?

Is transmission fluid thicker than engine oil?
