About 2 weeks ago I installed an AT trans cooler. I connected the cooler so the line out from the transmission passed through the built in radiator cooler first, then through the new transmission cooler, and finally back into the transmission. This seemed to work well, but I was having a slight leak with the steel braided hoses and standard clamps that I used. This weekend I changed all the hoses and lines so that they would accept Earl's AN fittings. Now everything is much more secure!

Here you can see all of the steel braided hoses I have for cooling heheheh... some are for the ARC oil cooler, and the others are for the new transmission cooler.


We took the original fittings off of the radiator transmission cooler and modified them to work with the AN fittings. Earl's sells a small fitting that you can weld onto existing fittings, allowing them to accept AN fittings.


On the hard fluid lines from the transmission (in and out), I had to cut off the flared line end, and install a special Earl's fitting. This fitting fits over hard lines and clamps on once tightened. Once installed, the fit is very secure and will not leak or come off - and it allows for a standard AN fitting to be used.
