How to replace the transmission oil in the Harley-Davidson Fat Boy?

In this tutorial, we can see how to replace the transmission oil in the Harley-Davidson Fat Boy, an extremely simple and fast operation. First of all, we wait for the engine to cool down sufficiently, then we unscrew the bolt containing the control rod located on the upper area of the engine itself. We then position a container underneath it, locate the bleed bolt of the transmission, not to be confused with the engine oil, and unscrew it with a Torx T40 wrench. At this point, we let all the oil in the system drain out, reassemble everything, and insert the new oil through the appropriate hole.
