The 1991 Chevy or GMC S10/S15 with a 5-speed manual transmission typically uses GM's manual transmission fluid, often referred to as GM Synchromesh or an equivalent fluid. The capacity for the transmission is approximately 2.5 to 3 quarts, depending on the specific model and configuration. Always check the owner's manual or service manual for exact specifications.
