At the front of the transmission, where the torque converter goes. The transmission will have to be removed. The awd trans of an outback is unique to most others in that the transmisson has the awd differential mounted on the front of the transmission to,operate the front wheels similar to a fwd transmission vs. having a transfer case with a front driveline going to a frontend. The fromt diff. Still takes gear oil. Your torque converter has a pump engagement shaft attatched to its hub that is about 10 inches or so that sticks through the dif. To engage the pump on the trans that is on the other side of the diff.. There is a shaft that seals the pump engagement shaft from the gear oil of the dif.. If you go through the trouble of removing the trans to replace the seal, check the fluid of the dif, and make sure there isnt any automatic tansmission fluid in it. If there is, more work than replacing the front pump seal will be required, you will waste your time putting it back in and prob cost you more in the long run. If it is fine, when replacing the seal, make sure the bushing isnt worn, if the bushimg is worn out, it will have to be replaced, or else it will still leak when you put it back in. make sure you know what your doimg before digging into a Subaru
There is a diPstick at the front on the transmission differential
