Which fluid to use for Toyota Diffs,Transfer Case and Manual transmissions

A Toyota Master Diagnostic Technician explains the differences in gear oil used in Differentials, Transfer Case and Manual transmission, which fluid to use for Toyota and how often to change them.

In this video I will explain the different types of gear oil for your Toyota and Lexus Differentials, Transfer case and Manual transmissions.

GL-3?GL-4?GL-5? what is the deal with all these ratings and which fluid is the right one to use in which application?

Folks this video was born in the spur of the moment as a viewer brought me their 2017 Toyota Tacoma 4x4 manual transmission but bought the incorrect fluid. We went out to a parts store to find the correct fluid and to my surprise it was not as simple as the labels were super confusing and I can see how errors can be made all thanks to companies marketing departments play on words!

Also while we're at it we'll cover why Toyota uses 75W in their transfer cases in newer trucks.

I like that reference, Toyota’s more worried about making reliable cars than naming their oils, it’s so true.

Side note, when changing differential fluid make sure you can remove the refill plug before removing the drain plug.

I am sure glad i took the time to watch this Video. I put the wrong oil in my 91 Toyota pickup manual Transmission and had to drain it and put the correct GL-4 gear oil. Better to change and be safe than regretting later down the road. Thank you!

A very strong facet of these videos is the vividness of the thumbnails. Not flashy or trendy, just very pertinent and relevant and appealing to the eye.

All the research and development to change my transfer case and left unsure until you say it. I trust that you say 75 90 every 30k I'm done researching. Thank you brother

Use RED LINE gear oil. They make GL-4 and is the BEST oil money can buy. I have 5 Toyotas 4 are 4x4 and 1 is a Corolla/Sprinter/Prizm Manual trans at 300K miles. Red-line oil made the shifting in the Corolla as equivalent to my 21 Taco manual. All diffs and transfer cases I use Valvoline 75W-80. Use Aluminum crush washers for Gear and Transfer case. Metal washer for diffs (but aluminum works for diffs as well). Excellent video!

This was an excellent point you brought up on GL ratings! No one usually sells GL-4 and if you don't know, you are buying GL-5 without a doubt.

Nice to finally get a clear answer to the the fluids and especially transfer case. I ended up using Red Line MT-LV recommended for toyota/lexus LF 75W GL-4 because i refused to pay the stupid amount for the toyota fluid.

Could have done with this video about 6 years ago when I did all the fluids on the FJ Cruiser TT that I had at the time. Best vehicle EVER.

I needed this video 6 months ago when I was super confused which oil to use in my 2016 manual transmission Corolla.
Even the dealer was clueless, telling me to use any 75w-90. No mention of any GLs.
I'm sure these lube techs everywhere you go just put whatever bulk gear oil they have in no matter what kind of car you have. I do everything to my own car That I possibly can. You just can't trust many people to do things right. Thanks for clearing this up.

[themessenger]

Thank you Car care nut. Thank you. I was so confused about what to put in my transfer case until I watch your video. Thank you and may the Lord bless and keep you.

I wonder how many people put Mobil 1 75w90 GL-5 in their Toyota manuals! I use Redline MT90 75w90 and it is clearly marked GL-4 and specifically states that it is safe for brass synchros. It is designed for manual transmissions and it gave a very noticeable improvement in shifter feel vs the original Dino oil. Thank you for another great presentation.

I put the Amsoil 75w-90 API-GL4 Manual Transmission & Transaxle Gear Lube into the manual transmission of my old Toyota Urban Cruiser. I loved the Easy Pack too. Amsoil got the API-GL4 in their products lineup.

[RastaJediX]

I love you, man. I bought some Redline MT-90 (GL-4, 75W-90) for my '15 Corolla 6MT and am trying to prepare myself for the change!

"...the world will not end..." Love it. My favorite Toyota care channel. Great videos, great guy.

For my 2014 Tundra 4x4 which tows our 7, 000 camper, I barely put 5, 000 miles a year so I just change out the diffs and xfer case every 2 years. I ordered from Blau Parts and they sent the German made Ravenhol oil, exactly what I needed! (And their diff oil bottles have those plastic extensions that make using them super easy...no pumping anything!!)

I remember grabbing two 75W-90 GL-5 gearoil on sale for $2 per quart before my first change of manual transmission oil, but I am very glad that I went for the Red Line MT-90. Quite expensive, but works very well on my little Yaris.
