Added a bunch of trans fluid, watched for leaks and nothing... It hasn't done it since and been fine since. Maybe yours did something similar?

Most likely came out the vent and hit the exhaust I had an 87 k10 Suburban with a 700 that hid that often . The trans did eventually go the new goodwrench had a long line on the vent to keep it from spraying the exhaust .
