I decided to go and change out all my ATF's to the specific Toyota fluid that is called for. I thought all of them were either T-V or WS. Bought 24 of each at my faithful Lexus Dealership. You will never guess
how surprised I was after draining the ATF out of my 2002 4Runner this afternoon. I took the 14 ml hex bolt in to get a new crush washer and as I was inspecting it I thought I saw "D II" stamped on it. I thought I better get
my reading glasses. I did and sure enough, big as day I confirmed the drain bolt said DEXRON II. I said to my self, somebody has inadvertently swapped transmission drain bolts because I know my 2002 would call
for T-IV. Then it hit me. Read the owner's manual and then I will prove this was just a simple bolt swap issue. Well, I got the owner's manual out and turned to the Transmission spec page and I couldn't believe what I saw.
My heart sunk. My transmission calls for DEXRON II.

What do I do? Please don't waste your time telling me to use Maxlife, please? Pretty please? No sugar on top though. :grin2:

I want to use whatever Toyota ATF I am supposed to. I know WS won't work. I don't think T-IV will work. Do I just go and find some generic Dexron III?

Remember, my point is not to use a multi-vehicle ATF. Amsoil is out. Schaeffers is out. Maxlife it out. I am of sound mind. I'm removing all my Amsoil and Schaeffers in my other car's transmissions and replacing with T-IV or WS.

Doesn't Dex 4 supersede Dex 2 and 3, meaning it can be safely used in place of the older formulas?

There is no such thing as Dexron 4. It is Dexron VI (6) a synthetic ATF that replaced Dexron III in the early 2000's. It does supersede the older Dexrons, is compatible with them and can be mixed with them ie: be used to top off a trans filled with Dexron II or III. You can get regular Toyota non synthetic ATF which is Dexron III. I got a case of it from the dealer when I installed a Toyota remanned trans in a customer's early 2000's Tundra a couple of years ago..

Nothing wrong. I just wanna go with the ATF that was specific for my transmission.

I just called 4 Toyota dealerships. One had never heard of it. The other 3 wanted between $11.50 (if i bring my own container) and $14/qt. Yikes!

Am I ignorant in wanting to use specifically what was called for when the 4Runner was new? Should I just go and buy some Valvoline Dexron III or is there something added in the Toyota non synthetic ATF that could be of value?

I actually got a case of quarts from Jaffarian Toyota Volvo in Haverhill, MA. They deliver to my shop in Kittery, ME. They recommended it for warranty purposes. I don't remember what it cost though. I could check the price and part number if I stop by my shop again today and check the customer's history on my computer. I really believe you are fine using Valvoline, Amalie or just about any other name brand Dexron III ATF. Dexron is a formula created and licensed by GM. As long as the bottle says Dexron approved it's the same stuff GM would use thus the same as Toyota would use.

MaineRunna,

That's too much trouble for you. You have already helped me enough. Thanks!

I am running Valvoline MaxLife on my tranny with no problem at all,

I'm using T-IV in my transmission. It is a beefed up Dexron to put it in layman's terms. The spec is not outdated like Dexron 3 either. Use what you have. It will work great.

I do not recommend Maxlife anymore. Relating back to your multi vehicle concern. Maxlife covers way too broad of viscosities. It meets WS and T-IV at the same time. How? Very fishy and no other manufacturer that I know of does this. That said, combining Dex2/3 with T-IV is very realistic. Viscosity wise they are quite similar, but T-IV has a little better additive pack. Most modern Dex/Merc fluids (which are not even licensed) meet T-IV spec. And Dex6 is closer to WS. Nothing scientific about this, but there you go. Only thing I can really argue is that the heat resistance of a synthetic multi vehicle like Amsoil or Redline outweighs the multi-vehicle blur.

I'm a big fan of synthetic transmission fluid. I had some chepo part store Asian vehicle special in there before and the shifts were hard and the transmission would jump around a bit. Upon switching to full synthetic the shifts have become smoother, quieter and more consistent in shift points.

Since Dextron II is no longer available you'll find a wide variety of transmission fluids being used. Our transmissions are still very bulletproof regardless of fluid type.

Why is your point to not use any multi-vehicle ATF? I can't think of anything more convenient than to have 1 ATF on hand. I use Amsoil synthetic ATF in everything and have since 1987.
I have 265K on a 1970 Chevy C-10 with a TH350 tranny that's never been opened up.
192K on a 2001 Mercury Grand Marquis.
198K on a 2002 Chevy Avalanche.
158K on a 2003 GMC Yukon.
The list goes on and on with past vehicles-everything from several older Mercedes to several GM front-wheel-drive setups with the 3800 engine.
I have never had a transmission problem and note that only one of these vehicles was purchased new, the others were switched over immediately after I got them.
You're overthinking this. Use the Amsoil in everything.

I personally would run synthetic ATF if I had an automatic. I run Redline MT90 in my 5spd. The part number for the Toyota ATF I used a few years ago was 00718-ATF00. It cost me 7.54/qt and listed for $9.43 at the time (July 2015)
