Couldn't find the one-stepper.
XY-Chain, A=6-->D=3 via ABCD; transport 3 from A to F via E; r4c5<>3.
Without further diagrams: W-Wing on 36 in boxes 16 with SL 3 in r5. Transport 6 from A to C; r4c5<>6. |

I seemed to have found the same solution path as Dan but viewed it as an almost xy-wing.
{xy-wing(67-3)r6c1+r5c2|r6c7} = (8)r6c7-(8=36)r46c9; -3r5c79
Note: To clarify my logic and the associated notation, I present the simple xy-wing in curly brackets, {}, assuming r6c7=37 and then add the almost condition, r6c7=8; the common deletions are listed.
