We have received the following from ZF (the Gearbox Manufacturer for most Land Rovers from 2005) Land Rover recommend the fluid and filter is changed at 150,000 miles!
Here's what the manufacturer has to say! "ZF recommends oil and filter changes after 50,000 to 75,000 miles to ensure optimum performance."
"Lifetime oil, the car manufacturer says you don't have to do anything, but that's not right! Just the car manufacturer says so, not the transmission manufacturer"
Did you know?
Most manufacturers now consider their Automatic transmission fluid to be "lifetime oil" unfortunately the oil still degrades over time and should be changed.
By draining and refilling you can leave up-to 70% of the total fluid inside the torque converter, Valve body and cooler lines!?
Here at Dakar we have a gearbox fluid flushing machine which changes up-to 98% of the oil within your automatic transmission.
So if you are experiencing one or more of the following problems this may be what you need.
■ Poor Shifting (shunting into gears)
■ Gear Slip
■ Torque Converter Hunting (rpm needle fluctuates whilst driving at a steady speed)
■ Delay in engaging gears when the engine is cold
Discovery 3, Range Rover Sport
These vehicles are notoriously hard to change the gearbox filter which is mounted inside the brittle plastic sump pan due to a chassis beam that runs across the bottom of the gearbox. Here at Dakar we stock and can fit at your discretion a Metal sump upgrade which aids in the labour costs and is much more robust for use in this vehicle.
