Hey all,
Well, I finally did my first valve adjustment. The car runs very well but the transmission went all funky. Before the adjustment it shifted smoothly, if somewhat softly. Now, it shifts hard, and when braking to a stop, it clunks into 3rd, or 2nd, or whatever it's downshifts to. What happened??? I double checked all the linkage and vacuum lines and everything looks right. The only real vacuum thing I disconnected was one of the lines from the connector on top of the valve cover. I had to pull out the brownish line that goes to near the EGR (not to the EGR, just near). I was an idiot and didn't write down which hole it was supposed to go to so I connected it to the to left hole in the rubber connector. Is this right?

I kind of like the harder shifts but the clunk while slowing down is not a very pleasant feel or sound. Thank you if you can help with this.

Alex
