I installed an auxillary transmission cooler and I used male/male hose barbs fittings and hose clamps to tie back into the stock rubber hoses. The connection between the auxillary cooler output and the stock transmission return line weeps only when driving. It does not leak while sitting in the garage. I have repositioned and retightened the hose clamps but the leak persists. I cannot tell if the leak is on the upstream side of the hosebarb center or on the downstream side.

Any tricks to try to stop the leak?

thanks all.
