Can the transmission lock cable leak internally on 63 Dart's 904 tranny?

Hi Guys, hope everyone is doing well this new year.

My 63 dart convertible is running pretty well but I am still having issues with the 904 leaking tranny fluid and it is making me crazy.

So far I have found a cross-threaded front coolant line fitting and replaced that. I found a crimped O-ring on the filler tube and replaced it. I replaced the gasket on the parking brake housing and the O-ring. I replaced the oil pan and gasket with the new deeper pan and re-usable gasket. I found a loose bore plug in the tranny and tightened it up.

I did find that there were 3 pan bolts that are stripped when I torqued them to 150 in/lbs so Ill figure that out but if anyone has suggestions I would appreciate it.

When I ran it in the garage there were no leaks so I took it on the road and drove around 10 miles or so and let it sit in the driveway while I checked the fluid and the fluid was fine but I found two spots where it leaked while it was sitting, so back into the garage and jacked it up and put in on my ramps and jack stands. I cant find anything obvious but saw that there was a few drips on the bottom of the pan, Upon further digging around I found that the driver side torsion bar was wet and had some dripping tranny fluid. I found the parking lock cable was touching the torsion bar and it was wet there down.

My question is: Is there any possibility the parking lock cable could be leaking internally? I recently replaced the O-ring into the housing.

Also is there anyone in the North Seattle area that might be able to put some eyes on this and help me figure out where the leak is coming from?

Cheers yall,
