Builds 2017 GX 460 (Now 2017 Tundra Build) (3 Viewers)

[CaptRussia253]

I just purchased a GX 460 last week. It didn’t come with a owners manual. I need some advise on diff, transfer case and transmission fluid.

Do I need a 75w85 or will a w90 or w140 be fine? I normally ran a thinker fluid in all my off road rigs. I have read that running a regular Dino oil in the diffs is better. Im a big fan of Lucas 85w140 but new to Toyota so not sure if it’s ok to use. Also, why the hell is Toyota’s 75w transfer case fluid so damn expensive? What’s a good option.

Do I need to change the transmission fluid? I hear it’s lift time fluid...

Thanks!

I hear it’s lift time

it sure is

for the fluid info, there are a few good threads on Club Lexus.

The X/fer case is simple.....along with rear diff.......front is sorta a PIA.....but not bad

Transmission ? I believe 100K miles is the suggested time

Bought an '11 w/95K on it & no service record on transmission

Took it to my closest Lexus dealer....$260 & they used Valvoline synthetic

Peace of mind for me....along with the gear boxes....

I'm frugal..used Super Tech syn gear oil from Walmart for diffs

Splurged with Ravenol 75-90 syn for the X/fer case...$18/liter

Register your car with Lexus on line....here's a manual for my '11

I’m reading to not use 75w90 in the transfer case. Only 75w should be used. Also, is anyone running a 85w140 weight? Or am I over thinking it and just should stick with a good ol 75w90 synthetic?

over thinking

look on Amazon for the Ravenol gear oil

 

[Washingtontaco]

Transmission service is @ 60K

 

[CaptRussia253]

over thinking

look on Amazon for the Ravenol gear oil

So a solid 75w90 in the transfer case should be fine?

did you open the PDF file in my above link ? 800 pages !!

Chapter 6-1 'specs' page 765

75w gear oil Toyota LF or equal

Can not see why any quality 75-90 synthetic gear oil isn't fine

PS.....don't forget the cabin filter in glove box !

Oh......you gotta have these shadow door lamps too........

Also a sticky at the top here with manuals listed

Went to Walmart and picked up air filter, cabin filter, oil filter and oil. Now need to pick up some diff fluid and transfer case.

Walmart on line....$35 order & free ship

They had your oil filter on the shelf ?

Robot or human?

Here's an interesting read about using dino gear oil being better for differentials. I might give the 85w140 lucas a try in the lexus. That's all I ran in my Nissan and what a lot of Tacoma owners use.

ECGS Gear Oil Recommendation

ECGS recommends Dino (Non-Synthetic) 85w140 Lucas oil with a Ford or Dana limited slip additive for clutch style posi's. The gear oil question is an age old debate that comes down to opinion. We base our opinion on differentials we have seen. Scientifically it has been proven that when measuring...

I'm far from a pro.......

synthetic for longer change intervals.....

Just keep it clean with either dino or syn......call it good !

That's what I was thinking. I like the fact dino for the clinging factory and lower temps in diffs and will change it out every 2-3 years. Super cheap insurance.
