In the old days that was considered a way to remove sludge. Not at all necessary with modern oils. I doubt if you will see any real problems as long as you change it ASAP.

good luck and let us know. :)

Suggested Repair

Change the engine oil as soon as possible. One quart of transmission fluid mixed with the oil is unlikely to cause real problems if the oil is changed promptly.
