Transmission hose drips..leaks

[Thumper580]

I'm having a hell of a time getting the 3/8" rubber hoses that connect the various hard lines on the transmission to NOT leak or drip. Used new rubber hoses and even double hose clamped them.... Still some will drip... Is there some magic that I'm unaware of?

Thanks, I know this isn't the biggest problem, but it's frustrating for such an apparent simple task.....
