What are the reasons for gear jumping in the Pajero V73 transmission?
2 Answers
The main reasons for gear jumping in the Pajero V73 transmission are as follows: Transmission gear issues: Excessive wear of transmission gears or gear sleeves, forming a conical shape along the length of the teeth. Detent ball wear problems: Wear of the shift fork shaft grooves and detent balls, as well as excessively soft or broken detent springs, causing the self-locking mechanism to fail. Transmission shaft problems: Wear and looseness of transmission shafts and bearings, or excessive axial clearance, leading to insufficient gear meshing and causing jumping and axial movement when the shaft rotates. Control mechanism issues: Deformation and looseness of the control mechanism, resulting in insufficient meshing of gears along the tooth length.
The Mitsubishi Pajero V73's transmission skipping gears can be caused by several common issues. Aging or insufficient transmission fluid leads to inadequate lubrication, causing internal components like the valve body to stick or wear out, resulting in unintended gear shifts. Additionally, faults in the electronic control system, such as a malfunctioning transmission control module or incorrect sensor signals, can cause the computer to misjudge shift timing. I've encountered many similar cases where owners neglected regular maintenance, failing to replace fluids on time, which accelerated the problem. It's advisable to first check the transmission fluid level and color; if it's black or has a burnt smell, it needs replacement. Also, inspect related fuses and wiring harness connections for looseness. Ignoring this issue can pose safety risks during high-speed driving, so it's best to have it diagnosed with professional equipment at a specialized repair shop.
