I just changed my oil Last weekend and looked over the entire drive train and it was clean as a whistle no drips or leaks anywhere I have put on about 250 miles since! I went out in the garage this morning their was a puddle of trans fluid on the ground about a half a quart at least!! I got under the truck and the back of the transmission was full of oil mainly around the wire harness that goes into the trans on the passenger rear!! Any Ideas what went wrong?? Or anyone else have this happen???

 

Common issue.
