What Is Mm Size Of Adapters To Adapt An Fittings To Trans For Cooler Lines Thanks

 

Coming out of the trans? Not metric 1/4" pipe. Russell makes a slick fitting that is a combination adapter/fitting so there is no need for a separate adapter. Adds a little extra clearance to the tunnel. Russell part number 612000. Works great!!

 

Okay im getting my trans rebuilt and m wondering if you really need and extra cooler or do you guys do it for reasurance? I know heat kills but I mean for minor bolt ons is it needed?
