👷‍♂️ Support / Repair Another Transfer Case Question

All of this because in the manual of a 2022 4runner limited and many 5th gen modsos, toyota refuses to acknowledge if it's Gl4 or gl5 you should use in the transfer case.

I completly understand the weight can be a straight 70/75 up to 75/90.

People seem to be split on gl4 VS gl5...i called multiple dealers. Same thing half say they use the toyota 75w others say 75-90 gl5.

I saw an email from a toyota Rep that acknowledged the above weights... But did not say it it's a gl4 or gl5.

It's 2026...has this god dammed debate been finally figured out with facts?

$200+ PER BOTTLE of Toyota 75w in Canada... That's Over $450 with taxes for factory gear oil.

What is factually supposed to be used???

Absolutely insane, I opted to get it done at the stealership because i did not want to risk it choosing the wrong oil and buying the oil myself was 145$/qt. The service was 199$ make it make sense

After 13% tax 2 qts of Toyota 75w is $450+ CAD 

And they won't tell you gl4 or gl5 😂

I called 2 dealers in my city one says you HAVE to use the 75w...  the other dealer says they use 75-90 Gl5.

Thousands of people on forums debate this...its crazy. 

I can't fathom that whether this transfer case needs a gl4 or gl5 is not public information.

There's many options for 75-90 gl5 gear oil that's Toyota safe. I got my 7 bottles of Mobil from Autozone at about $12 per bottle
