That looks like transmission fluid (red). Try cleaning around the transmission and up to the dipstick to see where new leaks appear. Don't forget to also check the transmission fluid level to maintain your fluid to where it's supposed to be.
Don't forget to also check around the external transmission filter.
edit: fluid also runs to a cooler inside the lower portion of the radiator.
