wrong transmission fluid?

This TSB has me a little worried:

http://www.etimago.com/yaris/TSB/TS-...0Fluid%20).pdf

So I read in the manual that you shouldn't have to flush the transmission, but I talked to the dealer, and he said if you live in a hilly area, and you are noticing rough shifts, you should probably flush it every 60-90k miles.

So when I'm getting my oil changed they say the transmission fluid needs to be changed(it actually looked a little dirty, and it was shifting hard). This is when I talked to the dealer, and went ahead an had it changed.

Well I hadn't read the TSB at this point, and the dealer didn't seem to care that I was taking it somewhere else to have it flushed, so I didn't see any problems.

The guy at the lube shop said they used "Mercon 7 Universal" which obviously is not genuine toyota ATF WS.

I haven't noticed any bad noised, vibrations, or hard shifting, but it does seem like the lag when downshifting(its automatic) has increased.

Will Mercon 7 mess up my transmission? And if so, is the lube shop liable at all?(I got it changed well after the TSB was released)

Flush it and get the Toyota WS.....there was only one other fluid that I could find that could be used in lieu of Toyota WS and it's made by Red Line. The viscosities etc of other than WS are not designed for our (auto) transmissions. I've even heard of Toyota dealers using their type IV instead. No No.

Also check your owners manual...it says what to only use.

I know it's not what you want to hear, but Klink10 is correct...

PS- Walmarts SuperTech brand has two tranny fluids they claim are compatible with type WS. I can't remember which ones, they say right on the back of the bottle. Would I use Super Tech? Just saying they exhist.

Ya I'm pretty sure the transmission fluid is not correct, and will have to be flushed.

Now my question is: is the lube shop responsible to get me the correct fluid? I would think they would pay the 250 for the dealer to do it, just so they don't end up having to replace my transmission...

I'm almost sure they are required to put the correct fluid in and/or replace the tranny if it suffers any damage, but can't find any exact legislation - anyone know a specific act or law that would cover this? I like to be prepared when I rip service managers a new one.

You are gonna be hard pressed on that one....they will probably turn it back on you for being a negligent(sp?) owner, not knowing the exact products being used at that particular quick lube and if they are compatible with in this case your car. I would just take the hit, resolve the issue elsewhere and salt the memory away for future reference.

Flushing is bad, Especially with a non-compatible hygroscopic fluid as is WS. Usually just partial drain and refill every 36K or not at all due to varnish loosening.

Leave it in and check the hot level if you see a slight performance change. The downshift lag would be determined by ECAT. Nice firm upshifts with no excess slippage? Dont fret your Good to go!

There is NO reverting, You can't go BACK to ATF-WS now anyhow. Who wants a hygroscopic oil in their tranny anyhow - probably have SHORTER service life with the toyota WS.

Well the word flush was used in general terms (as in get rid of). Not gonna argue...just don't see WS in that "off the web" Mercon-V ATF post. I do see where it may be used in "almost all" Toyotas as well as others. I have Googled WS transmission fluid and found countless entries on why you shoudn't. Anyway, if it works and he's happy...great.

Found this on the web also:

Surprise surprise, the lube shop didn't know what they were talking about...

They didn't use mercon 7, they used dexron 7

Still pretty sure it isn't good for the transmission, even though they swear its universal.

And they won't cover anything until there is damage done.. I'm gonna try to talk to a higher up and explain why spending 250 now is better than 1200+ later...

sigh.

I love how they recommend inspecting the fliud so frequently, yet turning around and saying it should never be changed...
