Transfer Case Cover for the LT230 transfer case assembly, sealing the main housing against contamination and retaining the internal lubricant.

The LT230 is the part-time four-wheel-drive transfer box driven from the main gearbox output on Defender, Discovery 1, and Range Rover Classic applications. The cover mounts to the transfer case housing and must seal correctly to prevent oil loss and the ingress of dirt and water, particularly important given the off-road environments these vehicles operate in.

Frequently asked questions

What is the GA9018 transfer case cover?

The GA9018 is a cover for the LT230 transfer case fitted to the Land Rover Defender (up to 2006), Discovery 1, and Range Rover Classic. It bolts to the transfer box housing and seals it, keeping the gear oil in and dirt and water out.

Which vehicles use the GA9018 transfer case cover?

The GA9018 fits the LT230 transfer case on the Defender 1986-2006, Discovery 1 1989-1998, and Range Rover Classic. On the Range Rover Classic it covers the 200Tdi, 300Tdi, and VM diesel applications. The LT230 is the part-time four-wheel-drive transfer box on these models.

Why would I need to replace the transfer case cover?

The transfer case cover is typically replaced when it's leaking oil or the sealing face is damaged or corroded. On the Defender, Discovery 1, and Range Rover Classic these boxes see hard off-road use, so a weeping cover that lets oil out and water in should be resealed or renewed.

What's involved in fitting the cover?

Fitting the GA9018 typically means catching the transfer box oil, unbolting the old cover, cleaning the mating face, and sealing the new one. Use a fresh gasket or sealant as appropriate and refill with the correct transfer box oil afterwards.
