Motor oil in the automatic transmission


I bought 1 quart of motor oil and 2 quarts of transmission fluid. Both were in blue valvoline containers. After putting in the first container of transmission fluid I checked the level and still needed more fluid. when I went to put more fluid in I accidently grabbed the motor oil and started to pour it into the transmission.

I realized before I poured maybe less than 1/4 of a quart into the transmission.

I was thinking that this amount is little enough that it probably wont hurt the transmission though I want to get a second opinion.
