Alright well here are the pics.
The first picture is how the whole deal works. Baisically when you're running your car eventually you'll go fast enough to where the little arm swings up and then the tab on the second gear hits it and it becomes engaged. When you slow down the arm folds back down and the tab is no longer caught on it and then first gear is engaged.

The second picture is of the screws to adjust it. I wish I knew which way to turn the adjustment screw but I've never had to mess with it so I really don't know. You'll have to expirement with it. If you guys end up figuring out how turning either way affects the shift point let us know.

The third picture is from the bottom of the car just showing you where the screws are.

The last one is of the access hole in the top of the transmission.

Hope this helps.
