Automatic Transmission Oil Pump for the 4-speed automatic gearbox, part of the transmission's internal hydraulic system.

The pump sits at the front of the gearbox and is driven by the torque converter hub. It draws automatic transmission fluid from the sump and delivers the pressurised flow that feeds the valve body, applies the clutches and bands, charges the torque converter and lubricates the internal components.

Adequate pump output is essential for correct gear engagement and shift quality; low or erratic line pressure is a common symptom of pump wear.

Frequently asked questions

What does the automatic transmission oil pump do?
The automatic transmission oil pump generates the hydraulic line pressure inside the 4-speed automatic gearbox. Mounted at the front of the box and driven by the torque converter hub, it draws ATF from the sump and feeds the valve body, applies the clutches and bands, and charges the torque converter. This is a ZF-manufactured OEM unit.
Which Land Rover models use this gearbox oil pump?
This gearbox oil pump fits the 4-speed automatic transmission in the Defender (1987-2006), Discovery 1, Discovery 2, Range Rover Classic and Range Rover P38. It's the same internal hydraulic pump across these applications. Confirm your vehicle runs the 4-speed automatic before ordering.
What are the signs of a worn transmission oil pump?
A worn transmission oil pump typically shows as low or erratic line pressure, which leads to delayed or harsh gear engagement, slipping under load and poor shift quality. Because the pump feeds every clutch and band in the gearbox, falling output usually affects all gears rather than one.
