magic disappearing coolant

i been losing coolant the past few months i have to fill the reservoir every week. i see the drip i smell the coolant . i took it to the shop pressure tested over night didn’t leak at all. no hose is leaking. the radiator is fine. heater core is fine. the drip is in an odd spot and doesnt leak large amounts or very often. it comes outta a hole wich is located next to the transmission but theres no clear view from the top with the intake on to see if theres any leak coming from that area.
*** ive noticed the car only leaks when the temp reaches the point when the cooling fans turn on,like when i sit in traffic**

please any input would be great at this point :unsure:

There is a metal coolant tube that connects the rear of the water pump to the coolant manifold that runs under the intake manifold. The upper rad hose and filler tube are connected to the coolant manifold. The thermostat is there also.

There are rubber “O” rings on either end of the tube. Either the tube is rusted/corroded through or the O ring in the rear of the coolant manifold is probably leaking. The coolant leaks from the rear of the engine above the transmission and drips down. To replace that tube or O ring you would have to remove the intake manifold to gain access to it.
