Ok, a bunch of places, check the shift cable O ring, the speedo cable & drive assembly, the Governor & modulator, trans pan gasket & fill tube. Also with a 63, check the cable that is on the right side that controls the park pawl. There are also diff axle seals (gear oil). There is also a seal behind the torque converter & a seal on the torque shaft at the trans input.
