Hey folks! Just did my 400 hr on my 3901 HST. With the exception of doing a really bad job transferring the waste oil into my disposal container (dust mitigation now I guess) all went well.

One question though. I had a drip from the bottom middle transmission drain plug. Nothing horrible, and I tightened it down until it stopped, but it seemed to take more torque to do that than a normal drain plug should. I don't recall there being a gasket on that bolt, and the diagram doesn't show one, but did I miss one?

Thanks for the help!
