I can't recall how much goes in there but ONE CUP rings a bell. The regular fill is on the side. The transmission fluid normally lubricates the u-joint in use but until it gets a chance to get back to the u-joint it must be pre-lubed via that small hole. You would only do that after a rebuild or fluid drain. All of the above is well described in the shop manual. | | |
