5th Gen Transfer Case Fluid

Does anyone know if any 75W-90 fluid is ok for my 5th Gen SR5 transfer case? Are there any requirements other than being 75W-90?

 

70W-90 works just fine.

The transfer case does have a synchromesh ring. Some say it’s not a big deal, but I’m playing it safe and using the toyota liquid gold gear oil as called for in the manual.

I had a TC failure. Not sure what caused it exactly, but the failure involved the synchro ring, and it happened while using an aftermarket gear oil I thought was supposed to be safe for synchros. I spent more time thinking of suitable gear oil options than it was truly worth. Just pay the man his money in return for a can of the good stuff.

Here are the details of my tc failure if you’re interested.

I used Redline MT-LV to split the difference between Toyota fluid and the 75W-90 going into my differentials. That's what I'd recommend for the budget-minded but get a quote for the Toyota stuff first.

(but also since I had some lying around already)

Synthetic 75w90 gear oil is all I have used in my xfer case for past 20 years in Toyotas.

Toyota specific fluid just fuel savings.

 

I used the Redline MT-LV for the transfer case as well vs the Redline 75W85 I used for the front and rear diffs. It may be my imagination but I felt the truck shifted into 4H & 4L more smoothly with the Redline transfer case fluid that with OEM.

 

I went with Redline MT-LV as well. Not only is it the same weight as stock but it's also a GL-4 which is safe for syncros.

2016? Should be able to use basic 75W-90.

 

I did a lot of research into what oil to use in the transfer case and after reading a lot of threads and watching the car care nut's video on it I decided 75W-90 was fine. I run amsoil and am changing the fluid every 30K but my second choice was Red Line MT-LV 70W/75W GL-4. I am going to perform an oil analysis at my next change out and will post it online once I get it back.

 

I use Redline MT-LV in the TC. Its Low sulfur formula lacks the reactive sulfurs found in most GL-5 oils that cause damage and is safe for brass synchronizers

 

I've used Ravenol SAE 75W in my Tacomas and now my 4R TC. No issues yet!

Trying to find Redline MT-LV seems to be out of stock on Amazon and most other dealers. The best I can find is the 1 gallon jug directly from Redline but their shipping is a bit high and they only have the 1 gallon jugs.

 

Here we go again. There’s numerous threads already. At least try to Google something first.

 

I am switching to Ravenol next time around in the 4Runner and Tacoma T-Case. Redline 75w85 GL5 in the diffs.

Used to be able to get the Toyota fluids for a little cheaper online through various dealer sales including free shipping but the cost for them now is just plain stupid.

 

Anyone use this stuff? I have this in my cart as an option.

Looks like it should work just fine.

I used Liqui Moly (motor oil) in another vehicle I owned and no complaints.

 

Good info.
