Ooops, I stand corrected...!
Earlier today I crawled underneath and saw that I do have a cooler, but I'm not 100% sure its for the Tranny tho. It's a single pipe with fins behind the front Bumper and right in front of the lower A/C Condensator.
It runs the lenght of the Radiator but from my point of view I can only see one black metal tubbing line that seems to go underneath the tranny, I can't see where it actually connects to.
Now from the top looking down into the engine bay I can see the tranny lines going to and from the Radiator. The one on top in of a bigger diammeter than the lower line... Which one is the return line? and does the procedure needs to be done differently if there's a tranny cooler installed?
