I'm going to get a 05' LR3 with the locking rear diff. I'm not sure how long it's been since the fluids have been changed so I thought I would change them just as a precaution. I looked up the recommended fluids in the manual and it looks like they're LR dealer fluids. I called a dealer and he said I could use 75-90 in the front diff but recommended LR fluid for the transfer case and rear diff. I tried searching and could only find a mention to Royal Purple maybe being compatible. I just want to make sure I put the correct fluid in each so I don't cause issues later down the road. The closest dealer is about 300 miles away so if I could find comparable fluid in town that would be great. The dealer fluid is also expensive. $23.62/qt for the transfer case and $45.26 for the rear diff. It looks like I would need 2 of each to do a drain and fill almost $140 in fluids.
Options for transfer case and diff fluids?
- Thread starter Roverfire
- Start date
Call the dealer and see if the parts department will check the bottle. There may be some information on the bottle that can help point you in the right direction. If I remember I'll call my parts guy and ask him to check a bottle.
If the bottle says 'for use in x speed transmissions' you know you either need D4 or D6 synthetic ATF.
Did you check disco3.co.uk?

From what I have heard, you want to stay with LR fluids on the 3 and 4.
The rear locker assembly looks like it was designed by NASA and a rebuilt one is $1700. Not worth saving a few bucks over IMO.
I am sure any dealer parts dept will sell and ship you the fluids.
Just my $0.02

On those vehicles I recommend the factory fluids. There is no benefit to taking a chance on a fluid that might not be compatible. The factory fluids don't have any performance problems I know of, so there is no functional reason I know to change away from them.
yes they do, and if you check you will find they do not have a compatibale fluid.
we use redline D4 for the transmission, but havent done any t-cases yet.
i suggest a diy'er use factory fluids, especially when its a 300 mile tow to nearest dealer to get a t-case replaced.
IF YOU CAN'T AFFORD IT NEW, YOU CANT AFFORD IT USED.
I think that's what I'm going to do. I have some Shell Spirax ASXR 75w-90 I'll use for the front diff and I'm going to pick up LR fluids for the TC and rear diff at the dealer when I'm down in Denver this weekend.
I've noticed on my LR4 all the components are marked FOMOCO, and found most fluids are the same as my F150 XLT 4X4 and all synthetic.
Your LR4 has a ford 5 liter in it, the LR3 has a jag engine in it, the V6's are a ford engine, which is why you see fordmotorcompany on some parts.
Ford, like most vehicle manufacturers, do not make the transmissions or transfer cases. So never use the same fluids in those components. If you look at the sump pan on your truck and it has a black finned thermoplastic sump pan it's a ZF transmission. Those transmissions take either dex3 or dex6 synthetic ATF. Dex6 is reverse compatibale, like all dexron trans fluid, but has a lower viscosity than dex3, so you need to be careful using the wrong fluids!
Like the other guys have mentioned, in the newer rovers when in doubt ONLY use rover fluids unless an oil manufacturer explicitly states it's compatible.
The newer rovers have issues with transfer cases and differentials. The LR2's haldex units like to fail right around warranty expiration. The LR3's have diff issues, not extremely common but common enough. So when you're already dealing with an inferior part the last thing you want to do is guesstimate the fluid you're using.

I thought the 5.0 in the LR4 is still an AJ-V8. It's just bigger with direct injection I thought I read.
Also, even though MOST of the electronics in my 4.4's have been Denso, SOME of the stuff, like ignition coils, had been replaced with FoMoCo stuff. (though some of the coils were still ND).
