I just re-installed my velvet drive (Model 10-17-004). Removed to replace the input and output shaft seals
due to leakage. I refilled with the proper Dextron ATF, but now it won't engage either fwd or rev. The selector seems to be moving normally, and engages the ball detent properly. Is there some sort of bleeding procedure that might be required? I don't believe I disturbed any of the internals when I replaced the seals-but you never know, it was my first try at this.
