Nissan Xterra no reverse gear issue after hearing a pop sound on Nissan Xterra

Some Nissan Xterra owners report experiencing a no reverse gear issue accompanied by a pop sound, which may indicate internal transmission failure. This problem could stem from a hydraulic loss of fluid to the reverse clutch or a failure of the reverse clutch itself. Additionally, owners are advised to check the transmission fluid level and condition, as low or dirty fluid can hinder gear engagement, including reverse. The LPS (Line Pressure Solenoid) switch is another potential culprit that may require inspection. Furthermore, a malfunction in the valve control box or rear solenoid could also contribute to difficulties in engaging reverse gear. Some owners may find that the pop sound suggests mechanical damage within the transmission, necessitating a thorough inspection by a qualified mechanic. If issues persist after checking basic components, it is recommended to consult a transmission specialist for a detailed diagnosis and appropriate repairs.
