4l60e cooler line fittings

[LS-K]

Im sure you’ve might have already made your mind up on what set up to use.

Here is my 2¢.

I initially went with the AN fittings and nylon washers. That only lasted me about 2K miles before I sprung a leak.

I went with the original GM fittings at the case that use the C-Clip lock thinks and then use 98-02 Camaro Camaro hardlines. I made a few tweaks to the hardlines, nothing crazy. I ran the hardlines till the reached, let’s say the crank pulley. I cut them off and used Earls hardline to AN compression fittings. From there I ran some fabbed up hoses to my front mounted trans cooler.
