LOL. I've installed a TF-2 kit and get nervous when I think about rebuilding the trans. You, on the other hand, have rebuilt your trans but get rattled by the shift kit. I just thought that was funny.
I was nervous about installing the TF-2 kit, but really, once I go started it was actually quite simple. Granted it took me all day, but I'd never been inside a transmission before and took my time.
