If your Suzuki Samurai's transmission won't go into reverse, it could be due to several issues. Common causes include low transmission fluid levels, a malfunctioning shift linkage, or internal transmission problems such as worn gears or a failing reverse gear. Additionally, issues with the clutch, if it's a manual transmission, may also prevent it from engaging reverse. A thorough inspection by a qualified mechanic is recommended to diagnose the exact issue.
