Special Radiator Fittings to Install a Transmission Cooler on a 2005 Jeep Wrangler 4.0

Question:

I have a 2005 Jeep TJ 4.0 automatic. I am trying to install a transmission cooler. I have the cooler installed but have not been able to find the correct fittings to connect the lines. I have both sets you have listed as needed but neither fit my application. My fittings have a large washer like part that presses against the radiator. When I removed the transmission line all the coolant came out of the radiator before the line came free from the factory cooler located inside my radiator. I know it may sound like i have lost my mind but that is how it works. After removing the line if i use the fittings i have it will not seal the radiator back up. I really dont want to cut my line and flair it. I would rather have the correct fitting. If there is one. Do you have this type of fitting? I can email you photos if that will help.

If I understand correctly, the line from the transmission to the radiator goes through a cavity in the radiator where there is coolant before the end of the line reaches the actual transmission cooler inside the radiator. Is that correct? Otherwise the coolant and transmission fluid would be mixing together and that would be very bad.

It sounds like the steel line needs to stay in the radiator and you would cut the hose and use fittings # D13028 instead of fitting something directly in place of the factory fittings at the radiator.

We do not have a fitting like what you are describing.
