$80/liter transfer case oil (1 Viewer)

[bloc]

I wonder the reason why did toyota removed the synchronizer in latest models, even LC300 transfer case doesn't have

Synchro may not be necessary in all-wheel-drive where the drivelines are almost always turning at the same speed.

Just a guess.

The synchro is in there, Toyota just doesn’t offer it separately after the 12/2011 build date. LF75W requirement began in 2010.

Stupid question.
I'm going to knockou my transfer case and front & rear diff fluids today.
I bought two bottles of Red Line MT-LV fluid 70W75 for the transfer case.
Front & Rear diff wise, I plan on using Mobil 1 75W-90. The only gear oil I can find at any of the auto stores is Mobil 1 75W-90 LS. Is this gear oil safe to use on the front and rear diffs?

While you are at it you might consider the IS drain plug for your front diff. Much harder to strip the head. 9090341-24016.

Can this drain plug be used on the top & bottom of the front diff on a 2015 LX570?

No. The drain plug on most toyota front diffs is much larger than the fill, due to it being the access point to check backlash.

I did the diffs and xfr case back in June and scored what I found to be a pretty good deal on Ravenol via blauparts. They sell a bundle for our rigs "Toyota Land Cruiser Transfer Case Differential Fluid Change Kit - 2013-21 Ravenol." After a discount code/tax/shipping the total was $228.67. This was a far better price than the crazy expensive OEM xfr fluid that I had originally ordered but was on backorder. I had planned to go OEM but I can't imagine these fluids are going to hurt me if I change these items every 40k miles.

Nice thing about the Ravenol bottles is that they have a hose on the end of them that makes it easy to fill so that a pump is not required.

That's exactly what I used for the diffs. Some of it was a few years old, left over from our previous 100 series. No issues after maybe 1500 miles.

Thank you!! You really saved my headache. I have a dilemma that I have to replace my transfer case, I can only have aftermarket choice and it's hard to find exactly correct part number Tcase.

So my question if the synchronizer is still present inside from 2007 to 2021 is there any significant mechanical difference between transfer cases with different part numbers??? can I use pre-75w Tcase in my 2016 LX570 model?

Thanks in advance

Toyota regularly runs pretty big sales, there was like 40% online sale. I got this "special" oil for pretty good price. If you don't tow, if you change it once in like 50k why gamble?

Ok cool. I actually called the local Lexus dealership and tried to order the part under # 9090341-24016. The guy at the parts counter said they couldn't find the part in the system.

Good deal, thanks for that heads-up!

Mobil Delvac is your friend. $10 a quart, full synthetic 75W90, no limited slip additive. It's very hard to find locally, so I just get lots of quarts of it at at time line with free shipping. I use it in my TC, it runs nice and quiet as this is an HD truck oil.

Mobil Delvac 1 Synthetic 75w90 is a GL5 as per Mobile spec sheet and not recommended for gear boxes with synchromesh (yellow metal). Toyota recommends a oil that is designed for a xfer case (with yellow metal) from 2010 and beyond...That would be a GL4 and Toyota wants 75w for the viscosity. GL4 gear oils do not have the EP additives that cause corrosion when in contact with yellow metal.

Summit .com left out the Mobil spec info about what not to use it in.

Double check the number from my post. It seems a 90 got added in there somewhere.

90341-24016 Is indeed a good number and should work in the Lexus system.

I was posting it in reference to use in diffs. It's one of the only synthetic non-boutique 75W90s that does not have a LS additive.

That being said I do use it in the TC in my 470, which allows GL5. It runs nice and quiet and looks great at yearly fluid changes.

I can’t say yes with total certainty, but they should swap w/o issue.

I appreciate the heads-up. I'll give them a call tomorrow with that #

Has anyone had success finding the Ravenol 75W in Canada?

as an aside, toyota has started using atf in the transfer for the new 2022 -present tundras, seems to shift a bit faster than my old tundra,
interesting to see they seem to think this is best now.

best or cheapest? They also got rid of dedicated transmission coolers in tundras from 2019 onward.
