I believe i have a trans cooler leak on the right side (pass side). Is there a hose on that side or would it be the cooler itself? Just trying to get an idea before I take it in. Will do it myself if simple enough. It is an 06 2500. No oil on front side of tranny cooler. Only back side and radiator. Probably 8 inches or so of the right side. Of course the engine bay and undercarriage is getting a good coating. Thanks

 

look at it and see if just a hose, even if it is the cooler, it will still be easy to replace.

 

Pretty tight and hard to see there. Is there a line on the passenger side? Or is it most likely a leaking core?
