My 2002 mercury sable Transmission won't go into gear?

If your 2002 Mercury Sable's transmission won't go into gear, it could be due to several issues, such as low Transmission Fluid, a faulty transmission solenoid, or a problem with the shifter linkage. First, check the transmission fluid level and condition; if it's low or dirty, consider changing it. If the fluid is fine, you may need to inspect the transmission components or take the vehicle to a mechanic for a diagnostic. It's essential to address transmission issues promptly to avoid further damage.
