Help with tranny cooler install

How have some of you installed a transmission cooler? I haven't looked at the connections on the transmission itself (I have an '05), but the ones on the radiator are the clip/O-ring type (not threaded), so it seems the only way to tap into the line is to cut into the rubber part.

Any suggestions? Thanks

On my '09 Montana van, I purchased a Hayden aux trannsmisison cooler rated for 5,000 lbs trailer. I hear the ATF oils run hot in GM vans. Thus, why I installed the next larger size cooler. Mounted this cooler in front of my van's A/C rad using 2 x "L" shaped steel rails with self tapping screws top and bottom. Very simply physical install. For its ATF piping, I cut the main rad's top hose (that has the rubber o-ring connector) and replaced with "L" shape replacement with normal solid brass connector. This replacement screwed into the top of the main rad. Luckily, I was able to purchase this special order "L" shapped steel hose (for only $8.00) at my local NAPA dealer.

If wondering, the factory o-ring connector simply unscrews from the rad. I unscrewed my van's o-ring connector and took to my NAPA store. They simply looked into their special order books and ordered my needed "L" shapped steel pipe - with proper solid steel connector (with matching threads) on it. Clean and simple. But, I did have to wait 3 days to obtain this special order part. Luckily, we had another vehicle we could use - while waiting for this special order part. But it was worth the wait...

Works great for my van...

Thanks for the reply...I just ended up tapping into the rubber hose part of the return line, connecting cooler lines with barbed connectors
