Please help 65,000 miles on truck tranny dripping on exhaust smoking can't find the leak will make a puddle after driving on ground.

 

I'm not to informed about your particular truck but since you say that it's leaking on the exhaust i'll assume that it comes from the side of the tranny.I would say check the lines to the cooler mostly you say it leaks after you stop it.(pressure relief).Hope it helps.
