Anybody on this thread know much about the new transmission fluid they claim never has to be changed?

I don't know what to think about it, in my opinion ALL transmission fluid needs to be changed periodically.

All I've heard about it is that the viscosity doesn't change much between the high and low tempertures.

i think the 06s have it as well. so i've heard (maybe i should check my manual)

My 07 4-runner manual says that it needs to be replaced at 100k. Toyota is claiming the new tundra fluid NEVER has to be changed. I don't know what to think about that.

Is it super synthetic or what? Even then i would think it still should be changed at 100k or even sooner if you're towing a lot.

i think it would be practical for toyota to use a maintenace schedule of 'never be changed,' if their responsibility falls short after 100k. they do boast a reputation of reliability and using a fluid that is service free adds to the luxury. however, that don't mean that it can't be changed. for some reason its been noted the dealers are recommending NOT to service WS ATF. its vague but I think world standard is really just another synthetic like amsoil or redline. and just to add, all synthetic hold their viscosity in hot or cold temperatures.

super synthetic? thats got to be expensive. :rolleyes:

Having owned some Euro brands, they too have used "lifetime" fluid in some of their auto trannys for a number of years. I know of one guy that has over 150k miles on his auto Jetta diesel without a blip and has never changed the fluid. I'm not a big tranny maintenance kind of guy, but I do think a fluid change at 50k mile intervals is smart if you're going to keep the thing forever. Most vehicle don't call for tranny changes until 100k miles.

Lifetime means "for the life of the transmission". Think about that for a second. :D

Switch to Amsoil and you probably never will have to change it again :tu:
Amsoil does not currently make an ATF that is compatible with the WS fluid to the best of my knowledge.

I had the automatic transmission fluid changed out in my new used 05 DC. It was replaced with the new Toyota WS fluid. There was a definite difference between the old fluid and the new fluid - the old fluid was brown. The new fluid was red.
Where did you have it done dealership?

Wrong sir. It is the preferred fluid used by IPT Performance Transmissions Torque Converters and Transmission Parts for Ford, GM, Chrysler, and Import vehicles and was vacuum flushed on a 2006 Tundra AC V8 4x4.

They use Amsoil Universal Synthetic Automatic Transmission Fluid
even on amsoil website it says you can use it to replace Type T & T4 ONLY it will not replace TOYOTA WS ATF there is NO replacement!! I called Toyota and they said the WS is a synthetic fluid and NEVER needs to be replaced!! even under extreme conditions!!

Probably a good idea since some people will put just about anything that they are brand loyal with in just about anything!! 05 D/C came from factory with WS and NO ONE has a replacement aftermarket substitue for this yet and Toyota told me this is a synthetic ATF and NEVER needed changing! I know this is hard to swallow, kinda like the 100K antifreeze but i guess technology/engineering advances will let them make these calls, i thought that their were typo's in manual which is common but the fluids are not typo's!! as far as quantitys i would be concerned that they could be wrong cause i have issues with that in my 06 D/C manual but no big diff!!

As pointed out by a couple of folks, this is old hat for a lot of German car owners. The problem isn't with the fluid per se, it's with the contamination buildup in the fluid. The clutch packs in any auto trans will wear and the particles from that wear has to go somewhere. What I don't understand is why they just don't use an external filter so you can replace the filter media without draining the trans.

We'll see how long these units last before problems crop up. The fluid may very well last the life of the unit and not cause any problems. BMW was calling their fluid "Lifetime" and after about 5 years, changed their minds and started calling for maintenance at 100K miles.

Fully agree with this.

If you're not running an external filter of some sorts, there's no way to trap the suspended clutch wear which in turn gets pumped into the whole lube circuit (bearings, bushings, thrustplates, planetaries, etc). I don't care how much toyota boasts that this fluid is a "lifetime" fill. I'll always change it at some earlier point for cheap insurance. At this point we don't know the longevity of these new transmissions and I'd hate to be the guinea pig finding this out.

The Germans have to use long maintanence interval capable fluids because the government has big environmental restrictions on getting rid of the old stuff - no curbside oil recycling like over here in the states! It costs you almost half the price of the new stuff to dispose of old lubricants over there. This is why you see so many cars on the autobahn blowing blue smoke - lack of proper oil changes under the conditions driven. It won't be long before our government imposes a similar situation. Enjoy your 3k dino oil changes and regular transmission fluid flushes while you still can 'cause things are gonna change in the near future!
