Hi All - have a trans leak at the cooler line to rad fitting. fitting to rad is fine but the quick conect appears leaking. couple questions: is this a jiffy fitting? there is some slack in this fitting, is there a oring at base of rad fitting? size? replaceable or is it integral to fitting? also if you pull rad fitting will cooling fluid need to be drained first? hopefully fitting is not integral to radiator. looking to tighten up this fitting.... thxs kenai
