If there is a transmission leak it will need to be investigated and repaired. Do you know what the code was example P1134 or P0303?
So many engine sensors, transmission sensors and brake and suspension sensors all interact with each other if one sensor goes out many systems can be affected. Keep an eye on the fluid level if it goes down you need to attend to the fault.
