The 1988 Chrysler LeBaron likely uses
conventional power steering fluid,
not ATF (automatic transmission fluid). However, it's
crucial to check your owner's manual for the specific recommendation. The manual will state the exact type and specifications of fluid required.
Using the wrong fluid can damage your power steering system. If you don't have the owner's manual, you can often find a digital copy online through a Chrysler parts website or a site like Haynes Manuals.
