Will an Automatic transmission from 1992 Chevy S10 4x4 fit 2002 4x4?

No, a 1992 Chevy S10 4x4 automatic transmission will almost certainly not fit a 2002 Chevy S10 4x4. While they're both S10s, there were significant changes to the drivetrain and transmission over that decade. The bolt patterns, input shafts, output shafts, and even the computer controls are likely incompatible. You'd run into numerous problems trying to force a fit. You'd need a transmission specifically designed for a 2002 S10 4x4.
