The Importance Of Air Checking

In this video, i am in the middle of rebuilding a 6L50. Before assembly i air check the clutch packs to make sure there are no leaks. The 1-2-3-4 clutch pack would not air check because of some problem with the stator rings so i ended up reusing the OE rings to get a good air check. If i would not have done this the transmission would not have worked and would have to pull back out again.
