What type of transmission fluid does a 1998 Ford F150 take?
A 1998 Ford F-150 requires Mercon ATF. However, it's crucial to double-check your owner's manual. While Mercon is generally correct for that year, there might be specific recommendations depending on the transmission type (e.g., 4R70W, 4R100) fitted to your particular truck. The owner's manual will provide the definitive answer.
