Range Rover Classic 200Tdi: change gearbox & transfer box oil

Transmission · Range Rover Classic (1970–96) · 1992–1994

How often: every 24,000 mi or 2 yrs, whichever comes first. Fresh oil keeps the synchromesh and transfer box bearings healthy.

Some of these intervals are more frequent than Land Rover's original schedule. That is deliberate for older vehicles.

Main gearbox	LT77 5-speed (ATF Dexron IID, ≈2.2 L) or ZF 4HP22 4-speed automatic: ATF Dexron IID, ≈8.5–9.1 L from dry (a drain and filter change takes about 4 L)
Transfer box	LT230 with viscous coupling: 80W-90, ≈2.8 L

Work safely: support the vehicle on axle stands, never a jack alone; let it cool first. Check figures against your workshop manual. You do this work at your own risk.
