4l60 rebuild reverse drum

  1. Reverse drum bench testing

    Transmission - Rearend
    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...
