Okay I need a new one of these. I'm having terrible shifting yet again, and a bit of flaring at low rpm in 1st gear. It shifts something awful.

Not sure how all of it happened in the first place, all I did was a valve adjustment :/

EDIT: Just threw the old piece of vacuum tubing on to the place it came from, and it shifted okay again. This piece of tubing was leaking, so I'm guessing that I have too much or too little vacuum going to this valve. However I can not adjust it because of the missing nut.
