Dear subaru fanatic!
I have done just as you said. The trans is in the car and the car is on a lift with the trans supported, as nearly level as it will get. when the TC assembly is slid into the case, it goes down smoothly and seems to engage the pump. The tube is mounted on the TC with the C-clip. I have spun the TC while supporting it, pulled it out and tried again about 20 times but it will still not go in all the way so that the TC is below the surface of the bell housing. It is blocked solid and I am at an impasse... What am I missing?
