Transmission cooler lines

Anyone know what size the transmission cooler lines are on a 02 3.7. They come in on the passengers side of the radiator. Two fittings and rubber hoses connect to the lines coming forward from the transmission. I was wondering about the fitting size and / or the hose ID. Thanks.

Having just installed a trans cooler myself last week, On a '02 liberty with a 3.7. I can tell you the size of the tubing 3/8 O.D. You can buy trans cooler hose at the parts store just for trans cooler lines in this size, will easily slide over tubing on raditior and on the cooler itself.(it's cheap) The trans cooler line you want to use is the bottom one out of the raditior, that should go to the new cooler (top fitting if mounting horzonialy) and then take the bottom fitting from new cooler and run some hose and couple it back into the bottom hose the stock cooler was connected to. So, what I did was, use the stock cooler, and then run the slightly cooled trans fluid through the air cooled trans cooler to get even more cooling of the fluid. this is probably the best method to plumb one of these up. After you get this done, check your trans fluid level, I had to add about 1 1/2 pints of fluid to get it up to proper lever on the dipstick, I guess the cooler adds a little fluid capacity to the trans.

Thanks for the reply. I was also thinking of adding a second trans filter and sensor for a trans temp guage. Hence the size question. I was wondering what size hose barbs to get for the filter mount.

The barbed hose coupling I used was 3/8" Which works perfect with the hose I bought, as it's marked, "Goodyear transmission cooler hose 3/8" So, I'm assuming that the barbed coupling is 3/8" O.D. and the hose is 3/8" I.D. Anyway, it worked out very well, no leaks, or real problems installing the cooler,

Quick question about the cooler lines. On my wife's 05 liberty one of the cooler lines is leaking by the radiator. it is leaking where the metal line meets the rubber line. There is a gap between the the two and when compared to the other line the other line does not have the gap. is there an o ring that came out or broke that caused the leak? is this a dealer only part?
