Turns out the Sonett transmission that I have is worn out. The bearings are shot. I'm going to get another one and see if that's good. A rebuild is $2,400 and up.

The floor in the trunk was swiss cheese. I cut the whole thing out. This should save me time in the end though because it means that I can make a custom battery box that will bolt in from the underside. That's awesome because I can just jack up all the batteries into place instead of lifting them into my trunk every time I need to trouble shoot something.
