11 Tundra 5.7 4wd ATF choices.

[Ursatdx]

I'm planning on doing a few drain and fills on the Tundra.
Just hit 100k. Very little towing, Daily driver.
My thoughts on ATFs
1) Toyota OEM WS
2) Idemitsu Type TLS-LV
3) Valvoline MaxLife

Any preferences on the ATF choices above?
Thanks in advance.
Merry Christmas!
God Bless America

I use Idemitsu WS equivalent in our '13 GS350.
My understanding is Toyota WS is not a synthetic fluid.

Good luck and have fun with it.

I would avoid a multimake fluid like #3. 1 and 2 are fine. Dexron VI is good too and synthetic.

Multi-vehicle fluids are not okay but using Dexron VI is? Huh?

Multi-vehicle doesn't mean multi-make. Multi-make is a compromise fluid formula made to suit numerous specs. Dexron VI has a specific formula made for GM and can be used in other vehicles calling for similar specs. Whenever I've asked here about Toyota transmission fluids, I've been told Dexron VI is the same stuff.

1 or 2 all WS I think that Idemitsu may make Toyota WS.

 

[The Critic]

Whenever I've asked here about Toyota transmission fluids, I've been told Dexron VI is the same stuff.

The only published similarity between Dexron VI and WS is the viscosity. Outside of viscosity, the formulation differences (wear pkg, friction modifiers, etc.) are unknown.

Well, I just flushed and changed the fluid in my Sequoia with D6 and it seems just fine, for now at least.

A 2003 Sequoia calls for T-IV, not Dexron or WS.

 

[atikovi]

WS supposed to supersede T-IV and is a better fluid overall. If the transmission blows up, I'll take that back.

WS does not replace T-IV in any application. Not sure where you read that.

The vehicle will be sold before any issues arise for you.

But the Maxlife fluid is ok? In applications originally using T-IV and WS?

 

[ZebRuaj]

Maxlife in all my Toyota's. Including my Tundra.

Also have a stash of Idemitsu from last year's clearance I've yet to use.

 

[Corollaman]

Maxlife will work great.

 

[meep]

not on your list, but amsoil signature series fuel efficient (lower vis) ATF has been stellar in both WS application I've used it in, 2006 Tundra 5 spd and 2014 lexus GS.

 

[Ursatdx]

I've also been looking at Ravenol T-WS.

RAVENOL ATF T-WS Lifetime is automatic transmission oil ATF on the basis of the latest technology of the HC/HT hydrocrack oils and PAO. Because of the special formulation the durability is twice the time than a comparable ATF oil.

Thanks for all of the helpful replies.

Any of those will be fine

Castrol Full Synthetic ATF is another good choice. Toyota transmissions usually aren't picky.

 

[Gebo]

I'd use the Toyota from your choices. I would not use the MaxLife.
