Auto Transmission Service Kit - service kit for the ZF four-speed automatic gearbox, covering the internal oil filter and its sealing components.

The oil screen sits inside the gearbox sump and filters the automatic transmission fluid before it reaches the pump and the hydraulic control circuit. The kit is used when draining and refilling the gearbox as part of a transmission fluid service, renewing the filter and the sump sealing components at the same time.

This kit includes the oil screen, seals, o-rings and sealing washer.

Frequently asked questions

What is the GA4500 Auto Transmission Service Kit used for?
The GA4500 kit renews the internal components of the ZF 4 speed automatic gearbox during a fluid service. It includes the oil screen that sits in the transmission sump, along with the seals, o-rings and sealing washer needed to reseal the sump after the fluid change.
Can the transmission service be done without specialist tools?
Fitting the GA4500 kit typically means dropping the gearbox sump pan to access the oil screen, which most home mechanics can do with basic hand tools and a way to catch and dispose of the old ATF. It's usually done alongside a full fluid drain and refill rather than as a standalone job.
Why does the transmission oil screen need replacing?
The oil screen in the ZF 4 speed gearbox sump filters automatic transmission fluid before it reaches the pump and hydraulic control circuit. Over time it can pick up debris and clutch material, which is why it's renewed together with the seals whenever the ATF is serviced, to keep the hydraulic circuit clean.
How do I know if my vehicle has the ZF 4 speed automatic gearbox this kit fits?
The GA4500 kit fits the ZF 4 speed automatic transmission used in the Defender up to 2006, Discovery 1 (1989-1998), Discovery 2 (1998-2004), Range Rover Classic and Range Rover P38 (1995-2002). Since some of these models offered manual and automatic options, confirm your vehicle has the ZF 4 speed auto box before ordering.
