Why won't my 87 ford aerostar move when put in gear?

If your 1987 Ford Aerostar won't move when put in gear, it could be due to several issues. Common causes include low Transmission Fluid, a malfunctioning transmission or shift linkage, or a problem with the torque converter. Additionally, issues with the differential or driveshaft could prevent movement. It's best to check fluid levels first and then consider having a mechanic diagnose the problem for a more accurate assessment.
