Torqueflite 904 front clutch question.
A lot of Torkflites come in with the wavy ring replaced by a flat one, but I replace it with the proper waved ring so that it won't have a harsh reverse. If you have a high stall converter, you can get away with it, but the waved ring works sort of like an acummulator, so just drill out the 2-3 shift hole to compensate for the waved ring and save your smooth reverse engagement so the ol lady don't complain when she gets back from WalMart.
