want to replace my trans lines with ss hose and an fittings when i add my cooler and swap in my new tranny.tried a search found others asking the same question with no answers.does any one know what thread/pitch the fittings need to be to screw into the 4l60e.it has had to been done someone help me out please!!!!!!!!!!

 

do not screw a tapered fitting into the case, it will bust. leave the adapters in the tranny and put your fitting in there.
should be 5/16 inverted flare. no promises.

 

thanks TJ
