Symptoms of Range Rover Gearbox Faults

Range Rover and Jaguar are luxury cars known for their outstanding performance, style and durability. However, when the control box has a problem, the owner needs to spend a lot of money to replace the internal components because they are scarce, expensive and require skilled repairmen to perform. Therefore, if you soon recognize the signs when the gearbox is faulty, you will quickly fix it and save more.

Range Rover gearbox fault refer to problems or malfunctions that occur with the transmission or transmission system of a Range Rover vehicle. These faults can vary in severity and can affect performance and drivability.

Here is a list of some common Range Rover Gearbox Faults error symptoms:

• The “gearbox error” warning appears on the control panel
• The “transmission error” warning appears on the control panel
• Difficulty shifting gears, gear selector not sensitive
• Strange sounds appear when shifting gears or decelerating
• Gear slip when shifting gears
• Difficult to accelerate

Cause of Range Rover Gearbox Faults

Here are some causes of gearbox fault on JLR models:

Gearbox module error: The gearbox will be controlled and operated more smoothly by different modules on the gearbox. When modules fail you may notice dashboard warning lights, transmission warning lights, gears getting stuck, not being able to shift gears, loss of connection between transmission and engine,… Most cases of gearbox failure are due to this reason.

Low gear oil level: Gear oil acts as a lubricant to help the gears and other components in the transmission operate more smoothly. When you do not regularly check the oil level causing it to drain beyond the specified amount, it can lead to a number of problems such as trouble shifting, erratic shifts, noise, slow gear shifts and dynamic check lights. light body.

Worn belt: Worn belts reduce the overall performance of the transmission. At this time, problems can appear such as shifting at high RPM, no reverse, slow shifting and jerky gear changes.

Torque converter is damaged: When the torque converter fails, the gears are more prone to slip, leading to overheating of the gear oil.

Defective gear shift module: When the gear shift module on your vehicle fails, it causes problems such as gears not running in the selected Gear or difficulty shifting gears.

Valve body is damaged: The body of the gearbox valve is the part that controls the clutches as well as the brakes in the gearbox, supporting a smoother and smoother gear shift. The structure of this part is quite complex, so when a failure occurs, it is difficult to detect. Users will feel difficult to shift gears, the gearshift mode is lame and difficult to switch between gears.

Damaged speed sensor: If you find it difficult to shift gears or get stuck in emergency mode, the problem may be from a damaged vehicle speed sensor.

Brake light switch: A damaged brake light switch on the engine can make it difficult to shift gears and stay in parking mode.

Steering angle sensor: This sensor is used in ABS and transmission control modules. If the steering angle sensor fails, an error code will be displayed along with the traction control light.

Software problem: Problems related to software glitches in the transmission control unit (TCU) can lead to erratic gear shift errors.

Low battery voltage: Although battery failure is rare, when a problem occurs, the communication line is interrupted. You will notice a large delay when changing gears or slowing down the car when needed.

Some common fault codes

Unusual symptoms you can feel in the car can only suspect a faulty transmission. When using a dedicated diagnostic machine, the following errors will appear:

• P0700: Transmission Control System Malfunction
• P0730: Incorrect Gear Ratio
• P0731: Gear 1 Incorrect Ratio
• P0732: Gear 2 Incorrect Ratio
• P0733: Gear 3 Incorrect Ratio
• P0734: Gear 4 Incorrect Ratio
• P0735: Gear 5 Incorrect Ratio
• P0736: Reverse Incorrect Ratio

How to fix the gearbox fault codes?

The error of the gearbox will more seriously affect the driving process if you do not fix it in time. Experts from Eurocartool suggest several ways to prevent further damage and minimize costly repairs. Here are some specific ways:

• Check the error code: Use the diagnostic tool pack JLR diagnostic software package (it includes 2 software SDD and Pathfinder) to check error codes and identify a specific problem with your transmission or transmission. You can refer to the error codes we provided above for reference. If you are inexperienced in using it, contact us for immediate help.

• Check the gearbox: The purpose of this inspection step is to identify visible signs of damage or leaks. You should check the oil level in the transmission and make sure it is the right one for your vehicle.
• Replace valve body and sleeve kit: If the error code is related to the valve body or the housing, replace them with a new one to prevent further damage.
• Test drive the car to check: After replacing the valve body and bushing set, do a road test to ensure that the transmission is working correctly. The purpose of the step is to check for any unusual noises, vibrations or shifting problems.
• Perform regular maintenance: Regular maintenance can help prevent gearbox failure. Follow the manufacturer’s recommended maintenance intervals and use the correct engine oil and filter for your vehicle.

When the transmission fails, you can identify problems through the transmission warning lights appearing on the dashboard, difficulty shifting gears and strange noises coming from the transmission. Most of the cause of the error is from the transmission control module, but with cars that have been used for a long time, you should check the mechanical parts such as transmission fluid, transmission sensor or line electricity.

While these problems can be handled well with experience, it’s safest to leave your Range Rover in a trusted dealer or auto repair shop for diagnosis and repair. properly treated.
