Low Lubricant Level
WARNING: This page is about a different car, the 2015 Fiat 500. However, it is still accessible from the selected car via links, so may be relevant.
Insufficient transmission lubricant is usually the result of leaks, or inaccurate fluid level check or refill method. Vehicle must be level to accurately check fluid level. Leakage is evident by the presence of oil around the leak point. If leakage is not evident, the condition is probably the result of an underfill.
