My brother just had his M body power steering box (82 New Yorker) refurbished by a professional steering box rebuilder. The rebuilder put Dextron III in the box and told my brother that using Dextron iii is what all the Chrysler boxes should be using. This caused us some concern as the shop manual says that Dextron iii should NOT be used, but to only use a regular power steering fluid. Don't think we ever come across one of these M body or variant cars with Dextron iii used for power steering.
Any thoughts?
