What happens if you mix oil and transmission fluid?

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.

Can you mix old and new transmission fluid?

This fluid starts to lose its standard properties and should be changed to keep the transmission parts and its performance at its peak. Mixing old and news fluids wont give you the ideal viscosity and the reduces the performance of the transmission system.
