First check the fluid level.

Then make sure the linkage is allowing it to go into drive.

Then check the modulator. Do you know what that is?
Be sure that the rubber line that connects the steel line to the vacuum modulator is connected. Also make sure the other end of the steel line is connected to the carb.

Of the connections are ok then disconnect the modulator and apply a vacuum to it to see that it is not leaking. Report back and we can discuss it more.

Go here and scroll down to modulator...

http://gmcmotorhome.info/transmission.html#mod

and this is what the metal vacuum line looks like -- check both ends to be sure the rubber fitting is not leaking...

Ain't that something? I used to live in Columbus. My great, great, great grandfather is buried in the Confederate cemetary there in town. Lost his life there during the war.
