You can print a vacuum line diagram for a 1987 Cutlass by visiting automotive repair websites like AutoZone, Chilton, or Haynes, which often provide free access to repair manuals and diagrams. Additionally, forums dedicated to classic cars or specific to Oldsmobile enthusiasts may have downloadable resources. If you have access to a local library, they may also have repair manuals that include vacuum diagrams. Lastly, checking eBay or similar sites for a physical service manual could be a good option.
Disconnect the battery (always disconnect the battery when working under the car!!!) Unplug the vacuum hose. Remove the retaining bolt. Pull out the old modulator. Slide in the new one. Replace the bolt and vacuum line. That's about it.

To replace the transmission modulator on a 1980 Cutlass Brougham, first, ensure the vehicle is parked on a level surface and the engine is off. Locate the modulator, typically found on the side of the transmission, and disconnect the vacuum line and any electrical connections. Remove the retaining bolt and carefully pull the modulator out. Install the new modulator by reversing the steps, ensuring a snug fit and reattaching the vacuum line properly.
