Ok, I know I know, I too did see this thread somewhere but now I can't find it. Can someone link me to it? Or just tell me why I am getting Tranny fluid it looks like on the rear of my truck. The other day I went over a good steep bridge and then noticed it when i parked. Now, I know my tranny is not the best, needs to be replaced really, but can I fix this for now? What would make it come out? I am always putting cardboard under to see where any leaks are and I have NEVER had any teanny fluid leak? so it must be when I am driving.
please help

 

check out to see if the undercarriage is wet (should be if you are getting it on the back of the runner). it will most likely be dry forward of where it is coming out and wet behind. perhaps this will give you a clue as to where the leak is at. could be a pinhole leak in a cooler line that only sprays with pressure, could be a rear main seal that only leaks while moving...who knows...do some more research. good luck!

 

It's going to be almost impossible for anyone here to tell you where it's leaking from, don't you think ?
Probably the easiest way is to get under the vehicle and start taking a look around.
It could be coming from any one of a dozen places or so.

Was your transmission recently serviced, maybe flushed?

That happened to me on my first roadtrip after it was serviced. It also coincided with the trans temp light coming on.
