Converting trans lines to an lines

uh, guys -
you ain't sposed to use regular an line for tranny cooler lines.
like any other rubber based line, it'll degrade internally and start losing bits into the trans - not cool.
if u insist on an, use hard line to an ends with adapters, or teflon line.

acutally my an-6 ss line is from earls, actually for use with NOS, has teflon inside instead of rubber!

I wonder how long it realy takes to degrade inside. especially since just about every trans cooler sold comes with rubber lines and hose clamps.

AN line for trans fluid

AN line for trans fluid

I'm using the regular AN line for my Trans Cooler return line. It's supposed to be good for 300 F continuous use in Oil. It is not rubber, but is a synthetic polymer. It is not supposed to be good for brake line, according to their catalog, but should be fine for Trans Oil. If U reach 300 F, your tranny is toast anyway.

You are correct, tranny tubing is not rubber. There are many articles and warnings that have circulated warning shops not to use "brake tubing" for transmission line repair. It is a common practice. The additional heat(doesn't have to get to 300 degrees) will cause "blisters" to form on the inside of the hose and those blisters will break off and get into the tranny. Make sure you use what comes with your cooler or you get hose that specifically states it will handle this purpose.
Later.
