You would find the HVAC vacuum line routing in a shop manual for that vehicle.
That transmission is all computer controlled. No vacuum lines on it.

how do you hook up vacuum lines in a 1988 Chevy nova
The heater/ac doors are all electric. They are not vacuum controlled.
The vacuum lines are on the roof.
On a 1994 Chevy Pickup 1500, the manifold absolute pressure (MAP) sensor is typically located on the intake manifold, near the throttle body. The vacuum line from the MAP sensor connects to a vacuum port on the intake manifold, which allows it to measure the manifold pressure accurately. Ensure the vacuum line is free of cracks or leaks for proper sensor functionality.

A diagram of the vacuum lines on a 2006 Chevy Silverado can be find in the service manual. It outlines their location and specific function within the vehicle.
Perhaps a carburetor rebuild, a complete tune up and an inspection of all vacuum lines and their routing should bring the emissions down to passing levels.
over time the vacuum lines can get clogged with gunk and not allow the actuators to engage the trans axle, so replace all the vacuum lines and if it still doesn't work its probably a bad actuator or the motor on top of the transmission.
