Where are the transmission vaccume lines on a 96 grand prix se?

On a 1996 Pontiac Grand Prix SE, the transmission vacuum lines typically run from the intake manifold to the transmission modulator. You can find these lines on the driver's side of the engine bay, near the firewall. It's often necessary to follow the lines visually from the intake to the transmission to locate them accurately, as they can be hidden by other components. If you're troubleshooting, make sure to check for any cracks or disconnections in the lines.
