Hi John,
There is one simple step I failed to mention (one which I carried out in my testing and had forgotten I'd done it).
After adjusting the Clips and Transitions sliders, then deleting the original 1 second transition, you need to extend the outgoing clip and the incoming clip to at least their original positions, or to their end/start positions (as if no transition had ever been inserted). This replaces the media that was used by the original transition.
To extend the clips, drag the end/beginning outwards respectively. That is, drag the outgoing clip end to the right and the incoming clip end to the left. Drag them as far as they will go, or at least add several seconds to each end. If you fully drag to the end of the first clip or the start of the second clip you will see a red line indicating that no further media is available. When you hover the skimmer over the end or beginning of a clip an arrow will appear (single or double-sided). When the arrow appears, click then drag the clip end.
After doing this, drag your new transition into the timeline. The transition should be exactly the length that you set in the Transitions slider under Settings. If required, double-click it to change it to a shorter duration in the Transitions adjustment tool in the normal way.
Sorry I missed explaining this step about extending the clip lengths after deleting the original transition. It was an oversight on my behalf.
John
