Now that would be different. You sure its trans fluid? The only way I know even possible for trans fluid to get up there would be if it were coming out of the pressure relief port or whatever its called, and if it were coming out of there I believe it would mean your channel gasket is blown and I dont think you could drive very long like that.
Check the trans fluid level and see where its at. See if there are any signs of transmission fluid around the drivers side or any getting on the ground under the car. Stuff like that. I dont see any other way for trans fluid to get up in that area of the motor.
