what is the recomended oil for the Gearbox & the Transfer case.

my haynes manual says multigrade engine oil Sae 20W/50 to API SF or SG for later boxes

for earlier boxes is says Hypoid gear oil SAE 80EP gearbox & SAE 90 EP for transfer box.

when the manual refers to early gearbox with limited slip differential is that the centre diff lock?

both haynes and LR factory manuals dont cover Auto Gearboxes. what oil do i need to get?

Cheers,

Chris

G`day

If it has the factory auto .

Dextron 11D is in the book but Dextron 111 is easily found , this is for the
Chrylser A727 torqueflite it hold 8.52 litres but will keep about 4 litres when drained .

EP 90 gear oil or similar is in the book for the transfer , up untill 1988 they all use the same type oil . Transfer holds 2.8 litres as long as it is mated to the torqueflite .

In 1969 to 1970 about 200 Range Rovers got a limited slip centre diff , it was only in the very first of them , it was replaced with a lockable centre diff .

Cheers

Thanks Pedro, yea i looked in the good oil thread but didnt find anything. but plenty of good stuff to read there got sidetracked a bit.

Hi PLR, great thanks for that. i had the haynes manual but wanted a 2nd opinion form the forum. great will give the box a service over the weekend!

cheers,
