Why would your 2001 ford explorer sport smell like oil burning and transmission fluid be foamy?

A burning oil smell in your 2001 Ford Explorer Sport could indicate an oil leak, causing oil to drip onto hot engine components and burn off. Foamy Transmission Fluid often results from contamination, such as coolant leaking into the transmission or aeration from low fluid levels or a failing pump. Both issues should be addressed promptly, as they can lead to more severe engine or transmission damage if left untreated. It's advisable to have the vehicle inspected by a mechanic to determine the exact cause and necessary repairs.
