My 04 Tacoma manual says to ONLY use toyota brand fluid in the auto tranny of the v6 taco. What is so special about the fluid and does this mean I cant use M1?

It seems to be a friction modified semi synthetic ATF.Lubeguard sells an additive that you add to regular Dex III to turn it into Toyota spec ATF.I guess adding this to M1 would make a nice ATF.
I have read that the ATF spec changed from Dex III with the 2003 model year change as opposed to an actual change to something internally in the transmissions.
My 02 Sienna specs DexIII while newer ones spec Toyota's stuff.Same with my 99 Corolla and my mothers 04 Corolla.
I wonder if there was any real internal changes inside the transmissions to need a more friction modified ATF?

The odd part is that the 4cyl trucks in 2004 still call for dexronIII while the v6 needs toy spec.
I use Amsoil ATF in my Vibes which call for Toyota type T-IV in the owners manual. So far it's been working great!
I would only use what's recommended during the warranty period in that Vibe and change more often if you like. Not bad to do anyway. It doesn't take long for auto fluid to dirty up. If it shifts any different from the stock fluid, either crisper or softer, it's probably not a good thing and the result of the Amsoil having a different level of FM than stock. I'm sure that Amsoil is great stuff but it seems manufacturers are designing their auto tranny's with very specific fluids in mind. Amsoil probably says it meets spec but that's not the same as being appproved for use.
I second that. I would not go messing around with your Auto Tranny Fluid for no particular reason. I have heard of to many auto trannys failing right after fluid type changes.
Just stick with the stock fluids for your autos, and change them as specified, you should never have any trouble.
Think about how many people DONT change there tranny fluid ever, and never have any trouble.
I would stick with the stock.

You summed it up perfectly
The reason a lot of transmissions fail right after oil changes is that the oil was left in too long and varnish built up. The new oil starts cleaning and clogs the filter ansd sometimes other the small tolerances between shafts and valves. A second change usually fixes things.
Proprietary factory fill ATF is "barely adequate fluid"?
Oh well, since this is an election year, I suppose one more off-the-wall conspiracy theory is par for the course...

When Toyota changed the Tundra transmission fluid requirement in 2003, there also was a model number change on the plate on the side of the transmission.
Toyota Type T-IV ATF is different from Dexron-III. The only substitutes are unlicensed Amsoil ATF and unlicensed Dexron-III plus Lubegard HFM black-bottle supplement.

You can also go with Mobil's Type T-IV approved fluid but it has been elusive to find. The Toyota Type T-IV fluid costs almost $4 per quart.

Thats funny, I emailed Mobil a couple of months ago and they told me they did not make anything for Type IV requirments.
What is funny is you can't find it anywhere!
I found this yesterday. I dont know whether this is considered licensed or not, but amsoil claims they are approved substitute for type T-IV.

Well, the stuff Toyota sells IS in a Mobil bottle, but they used to sell stuff made in Japan by Idemitsu or something...
thank you all for your info!
I have purchased Type T-IV ATF at the dealership for $3.93 a quart so the dealership might be a good place to start. I don't know of any sources online other than Amsoil.
The stuff I purchased at the dealership recently are in black bottles, Toyota labeling, maybe its different where you get it. I would like to get a hold of the Mobil stuff if its cheaper.
