Rant about Trans Cooler Lines

[hatzie]

Dorman 800-614 are the female Jiffy Tite transmission line fittings.
The Mastercool hydraulic fitting forming tool works great. Kinda pricey but it works great. Maybe you could find someone to form the ends of a 3/8" Ni-Copp roll.

The SAE J1910 transmission cooler hose lasts 5-10 years. If it's installed with replaceable clamps you can install a new section when it leaks.
The cooling pack is mounted to the body so there's some flex between that and the engine/transmission package. If you don't have the rubber hose to take up the flexion the lines will crack.

Here's what I ended up doing.
(Using an Eccentric Flaring Tool, which is AWESOME!)

Cut the line coming out of the radiator's trans cooler, then flared the end, connected to a brass flare union, then to a flared steel line, bent to go to around the radiator to the new transmission cooler.

This got annoyingly tricky, because the new transmission cooler uses flares BUT where a flare nut would thread in, it's too deep - the flats of the nut hit the top of the female before the flare seats inside. So...using my old double-flare tool to start a double (or inverted) flare, then the eccentric tool to finish the double flare, that made the flare thick enough to seat before the flats on the top of the nut bottomed out.

Same double-flare drill on the outlet of the trans cooler, then steel line going back around the radiator to another brass flare union, which connects to the newly-flared end of the steel line back to the transmission.

Probably took 1.5 hrs to actually do all that, and 6 hrs looking, poking, thinking, and figuring it out.
