I am rebuilding a manual trans. for my 2002 Outback and found that the snap ring had come out of the viscopling. I have reassembled the coupling and will install a heaver snap ring in it but am wondering what fluid do I put in it. Or is trying to repair this even a good idea? Should I just spend the money and install a new one. If so are the ones on e-bay for around $250.00 any good (rebuilt from China) or should I just speed the money and get a new on from Subaru. I plan on keeping the car and am also rebuilding the engine and want everything right.
