What manual fluid does 1998 Chevy s10 2.2 liter take?

A 1998 Chevy S10 with a 2.2L engine uses GM Manual Transmission Fluid. The specific type will depend on the exact transmission in your truck (some variations exist). Check your owner's manual for the exact specification, but it's likely to be something like Dexron II or III (or a similar GM-approved equivalent). You'll find this information on a sticker inside the driver's side door jamb or in the owner's manual. Do not use any other type of fluid as it may severely damage the transmission.
