Hey new to the forum here. Rebuilding my 2nd 4l60. While Air testing the reverse drum, I have leakage past the stator rings. The piston will apply but it leaks quite a bit. Is this acceptable for scarf cut rings. I used them on my other build and they did not leak but they do on this one. Reverse drum is in good shape were the rings seal. I ordered some solid ones just incase. I heard that a bit of leakage is ok since air can get by the rings better than the thick atf.
