trans leak

I started my 67 Goat again and got my good 20 mins at 2000 rpm.

but...BOTH of my trans lines that enter my radiator (aluminum) are leaking badly where the metal lines go into the bottom of the rad.
I tried tightening them with out monkey pawing it......but it didnt stop leaking.
what can I do?
thanks as always

Did you chase the threads on the radiator and the cooling lines to clean them?

I had a similar issue on the top cooling line when the line was as tight as it was gonna go ... although not wise: a very small tab of pipe dope was applied to the thread at the base of the cooling line making sure the threads that enter the radiator did not have any on them. Problem solved. You can try some teflon tape too.

I didn't chase the threads. the connections went in easily. Its a new radiator.
I did chase the thread on the fitting with a nut that fit prior to istalling the lines.
I understand those lines are low pressure?
teflon tape eh?
what's pipe dope?
cool
thanks as always

New radiator has paint on the threads no doubt. The paint may be preventing a tight seal. If you tap the hole it will clean out any paint or other debris.

Even a slight piece of dirt caught in the threads can cause a leak.

Pipe dope similar to plumbers putty. A little dab ill do ya. Make sure none gets into the radiator. Begin threading the end into the radiator and then place a small dab on the tail end of the threads so it seats in the radiator threads. You can try teflon tape too but not sure if the heat will affect it.

Yea its low flow just transmission fluid in there. They just need snugged up, make sure you don't over torque you'll have major issues.
