Possible reasons for the lack of reverse gear in a Mitsubishi Pajero with automatic transmission:
Mechanical problems:
*Low transmission fluid level: Check fluid level and add fluid if necessary.
* Burnt out reverse clutch pack: Replacement of the clutch pack will be required if it is damaged.
* Faulty valve body: The valve body may be clogged or contain faulty valves, preventing the vehicle from shifting into reverse gear.
*Damaged Brake Band: The brake band may be worn or damaged, causing the vehicle to not reverse.
Electrical problems:
* Faulty shifter: The shifter may not send the correct signal to the transmission.
* Open Wiring: A break in the wiring connecting the gear selector and transmission can result in the vehicle not being able to reverse.
*Faulty Transmission Control Module: The transmission control module may be faulty and not providing power to the reverse gear.
Other possible reasons:
* Frozen or seized transmission: In cold climates, the transmission may freeze or seize, preventing reverse gear from engaging.
* Pan Biting: The transmission pan may become warped or jammed, preventing the transmission from shifting.
Diagnostics and repair:
To accurately determine the reason for the lack of reverse gear, you will need to have the car diagnosed by a specialist. Diagnostics include checking fluid levels, inspecting mechanical components, and using a trouble code scanner. Once the cause is determined, appropriate repairs can be made, which may include replacing the fluid, restoring friction linings, repairing the valve body or electrical wiring.
