It leaks when it sits. I think I identified the leak coming from the o-ring at the filler tube, which I replaced. I thought that fixed it but no. My question is whether the fluid level is supposed to be above that o-ring joint. I'm wondering if the fluid is supposed to be staying in the torque converter but due to internal seal or other issues it is draining back into the pan. I wouldn't think they'd design a crappy o-ring seal at the oil filler tube that is intended to be below the level of the fluid.
