the case, minus a few cans!

On the 123 body, it is very very rare to lose the center vent switchover valve.

Thanks Karl - will take a look see now that I know where to look. It was intermittent for a while whitch lead me to beleive it was the switchover valve.

Tom, This situation is the default setting when there is not enough vacuum to operate the vacuum elements which control where the air comes out. You might have a leak. follow the vacuum line from the top of the vacuum pump on the front of the engine. Remove the left two lines and block the vacuum fitting with two golf tees. This experiment should do the trick and provide smoother shifting and smoother running engine. If it doesn't work, replace the vacuum hose coming off the vacuum pump with a piece of new vacuum hose and check all the plastic vacuum lines to make sure they are sealed at each end. You may need to replace the vacuum elements. Get a vacuum gauge for about $20 at Sears and remove the glove box lining. There is usually a vacuum bar with lines going to it. You can plug the vacuum gauge hose into each and see if it reads any vacuum. If some do, and some don't, you'll need to remove the dashboard to replace the vacuum elements. They are availble from Rusty (buymbparts.com) at 800-741-5252. P.
