2005 Toyota Corolla - Fluid levels

I have a 2005 Toyota corolla LE and the transmission fluid level is very low and the engine oil level is very high. Is it possible for the transmission fluid to get into the engine oil by itself.

No, it can’t. Fill the transmission to the full line and check it regularly.

Did you just have the oil changed at a jiffy lube type place? I wonder if they accidentally drained the transmission and then filled the oil
