I just finished putting my 89 D250 back together, and this morning I noticed a puddle of ATF underneath the front end of the truck. Upon starting the truck, ATF started pouring out of the cooler in front of the radiator support, right above where the a/c condenser goes.

Where can I get a replacement cooler? Would Mopar have it? I've checked NAPA and they don't have anything.

Thanks.
