my trans fluid is leaking when i run it in park but i cant tell wear its leaking from have any of you had this problem where are some common places the trans leaks

 

there are several places where transmission fluid can leak; best way to figure out is to jack up the truck and look underneath it to pinpoint where exactly the leak is at. Common leaks are the oil pan, cooler lines, front pump seal, extension housing seal, speedometer o-ring & filler pipe o-ring . Like I said, you just need to get underneath your truck and see where it's at.
