Can you use a 2 wheel drive trans in 93 Ford Explorer 4wd if so what years?
No, you cannot directly use a 2WD transmission in a 1993 Ford Explorer 4WD. The transfer case is integrated into the 4WD transmission, and the 2WD transmission is not designed to accommodate this. The bolt patterns, input shaft lengths, and overall case design are different. You'd need to replace far more than just the transmission—potentially the entire drivetrain.
