On my 99 suburban I have a leak where my trans line goes into the radiator. What should I use to seal it with? Permatex, silcon tape, elbow grease?

Is it a threaded fitting or does it have a rubber hose clamped on to the radiator?

Okay, that actually makes it easier. Carefully remove the fitting and place teflon tape around the threads and replace it. That should take care of the leak. Please be careful when removing it. If it is corroded, when you turn the nut, the tubing can bend.

Try that and let me know if it helps.
