Range Rover P38 # 094 - Differential and Transfer Case Oil Change

The front and rear differential takes 1.6 liters (3.4 US pints) of 75W/90 gear oil when refilling.
Oil should be changes every 160.000 km (100.000 miles) unless it's a new differential. Then change the oil after 10.000 km (6.000 miles) since there'll be debris from manufacturing and wear-in.
The transfer case takes 2.0 liters (4.2 US pints) of ATF Dexron III automatic transmission oil when refilling.
Oil change every 40.000 km or 2 years. Whichever comes first.
Both are filled until it starts to seep out of the fill plug.
I used Hylomar Hylosil 100 Series (DA6441) thread sealant on the drain and fill plugs.

NEVER EVER remove a drain plug without removing the fill plug first!!! If the fill plug is stripped or seized, you will not be able to refill... This goes for Diffs, Transfer case and Transmission.

[@bvingerh]

Also: the oil flows out much easier and straighter (without glugging) if air can enter from the fill hole instead of from the drain.

I also performed these works in my car and also changed the liquid in the automatic box in May 2019. My stallion smiles contentedly. Now ordered the crankshaft sensor, I will change. Then again I will go to the forest and pull another bus out of the swamp.

Good luck, and thanks for watching! :)

Man thank you so much I have learned a lot from you. On my Range Rover I did replaced my fuel pump following all your tricks thanks.

[@WorkOnP38]

Great work, Lesly. Glad my videos could be of help. Thanks for watching!

[@jeremys1214]

I've been watching all your videos for some time, so helpful and now doing most of the maintanance work on my Diesel RR. Keep the videos coming as great to watch and learn.

[@joharcc]

Super useful! Thank you. Please keep posting!

[@asomind]

This videos are great man. Working on a p38 is easy enough this gives me a lot of confidence. Already done the balljoints and air con thanks to you!

[@WorkOnP38]

Glad you found them useful. Awesome to hear success stories! Thanks for watching and sharing.

@@WorkOnP38 tomorrow is axles gearbox and transfer box oil change. Thanks!

[@mrsmith6316]

I always put Lucas transfix in the diffs and trans. Makes a big difference and really improves gear changes on the auto. Note* I have no affiliation to Lucas but it works for me 😁

[@WorkOnP38]

I'll look into that. Thanks for sharing and watching!

[@dontdoit6403]

Same goes for oil always one quart less leave room for lucas.👍

[@zomisland03]

Thank you for sharing I have a 1999 RR and starting to do my own work on it it so very informative information.

[@WorkOnP38]

Hi Ron. Glad you can find use in the videos. Good luck with working on your car. Thanks for watching!

[@user-zc5de3ds8n]

hi! forgive my boldness but you must first loosen the fill plug! what if you spilled the oil and that cork didn't come off?)))

[@iknutis]

Agree :)

[@WorkOnP38]

That's a good tip. Thanks for watching!

[@chrisgreenwood271]

Subscribed, I'm on the look out for a p38.

[@WorkOnP38]

Thanks for watching and subscribing. Good luck on your P38 hunt. I hope you find a nice good one.

[@chrisgreenwood271]

@@WorkOnP38 picked one up yesterday, I think I've found a good one, amongst the many poor examples I have looked at. Keep the videos coming very informative. 👍

[@jimmcculloch3786]

Sir, just, Thank you, Thank you, Thank you. :)

[@estebanserrano1303]

I'm going to go see a 2000 4.6 HSE V8 Petrol this week for possible purchase here in USA, Do you have any tips of what to look out for that can be expensive to repair? I know head gasket replacement is expensive but are there other things to look out for? Thank you. I really enjoy your videos.

когда сливаешь масло нужно сначала открутить заливную пробку, затем сливную, тогда масло будет сливаться ровной струёй.

[@MIL-STD]

Thank you, I will be doing this soon.

,Hi. Great videos. Very well presented and explained. I have a discovery 2 , 2003, SE7 .with 50 K miles. It’s a 4.9 Petrol. I keep it in Portugal and only use it 4/5 times a year ,for the last ten years. I’ve had the engine oil changed and this year I found the gears changing a little rough when first started. That’s why I found your channel. I’ve now decided to change all diff oils, gearbox fluid and transfer box fluid. I ve also had the brake lines flushed two years ago but I still find the brakes very hard . Ie slow to stop the Jeep. Can you suggest anything about the brakes and anything else I should be doing. Cheers for your help and keep up the videos. Pat.

[@stevenwilliams9280]

Are the transfer case bolts also 1/2” 4-pointers?

I have range rover p38 2001, i had problem in damage rear pipe from lit to right how to replacement and change

[@360ps3lol]

Alright mate. When changing the transfer case oil do you still use the auto transmission fluid if it's a Manual. I'm really struggling finding info in the Manual boxes

[@user-zc5de3ds8n]

I changed the oil like you on my RR but it went through the shaft seals! put new oil seals but the oil goes away! please tell me how to solve the problem.

[@iknutis]

Дед Мороз I’m guessing either the seals was incorrectly seated, or your shafts are too low and should be adjusted upwards. It could also be a clogged diff-breather, so that the pressure build up.

[@leslydauphin2501]

Right now the only problem that I have its my idle the RPM its very high. Let me what I have to do ?

[@pauloarce8770]

how can I test the differential and test the universal joint?

[@bartekbartek7073]

do you use dexron 3 oil for the reducer?

[@collinbarrows1932]

2000 P38 250,000 miles: Would 80w-90 hurt the diff? What brand of oil do you recommend?

[@WorkOnP38]

Hi Collin. I wouldn't have the expertise to recommend one brand over another. Sorry. I'm not sure if 80W-90 would hurt. I would imagine not, but I'd stick with the manufacturer recommendations if you can. Thanks for watching!
