Low Fluid Level (CVT)
WARNING: This page is about a different car, the 2005 Mercury Montego, 2005 Ford Freestyle, and 2005 Ford Five Hundred. However, it is still accessible from the selected car via links, so may be relevant.
A low fluid level could result in poor transaxle engagement, slipping of the chain, malfunction and damage to the transaxle variators. This could also indicate a leak in one of the transaxle seals or gaskets.
