Toyota ATF TYPE T-IV for my 95

Going to do a drain/refill on my 95 auto tranny 4x4 6-cyl....Toyota ATF TYPE T-IV is what I need correct?

 

I thought it was spec'ed at TYPE 3, but the succeeding types will also work. So TYPE IV will work also

 

So I think 10 or 12 quarts should be enough for full drain and refill.

I can get 12 quarts of Toyota T-IV mineral transmission fluid for $85 shipped

Mobil ATF 3309 is the same I believe

 

Drain and fill will only get about 4 quarts out at the most. Use the cheapest Dex III you can find, and it'll be fine. I use DEXIII in my a340 racetruck, cheapest i can get my hands on.

 

What about draining the hoses near the radiator too. Drain and fill a few times?

 

And since you're messing with transmission fluid, might as well 'turkey baster' the power steering reservoir out and get some fresh fluids in there, if you haven't already.
I think most guys here like that red/orange bottle Valvoline synthetic stuff for ATF.
I guess if cost is really not a factor then Toyota ATF fluid is fine, of course.

 

I had a new OEM rack put in a few weeks ago along with fresh fluid all through

 

Well sure that would get some more out. I just drain a fill every few oil changes because it's easy. I'm a little bit lazy sometimes.

 

I agree with post above about a Dexron III fluid. Our old trusty auto transmissions will likely see little to no benefit from the 'upgraded' trans fluid formulas.
Might be tough to track down some Dexron III but I'll bet you can get it cheap if you find some.

 

That's how I did mine when I got my taco. Drained and filled like 3 times that first month and the shifting definitely improved and was noticeable.
If you're going the drain and fill route, there isn't much benefit in doing extra disassembly or work to get an extra quarter of a quart or half of a quart out, know what I mean?(not necessarily asking you vasinvictor, just saying )

 

Dex III was a name brand, it's not made anymore, however, you can find DeX III equivalent. You just have to read the label. I bought some the other day.

 

Just going to stick with TYPE T-IV

 

To the OP, careful draining all the fluid out and a transmission that has never been serviced. All the grit in the fluid is clutch material and if the clutches are really worn, it needs that grit to function.

 

The manual specifically calls for Dex II or III. IV is another thing entirely.


EDIT: At least thats what I read once. I dunno, seems like there might be more of a debate about that then I thought...

ANOTHER EDIT: Sounds like using Dex IV in a transfer case or power steering pump specced for DEX III might be bad.

 

I dropped the pan 2 years ago and cleaned it so well along with the magnets. I just want to drain out of the plug and refill thru dipstick

 

Where could I find a case of 6/12 of the Toyota II or III?

Or either of these below?

You got me second guessing, I could easily be mistaken. This is from the Toyota auto transmission wikipedia page. But that's not necessarily the most reliable source.

In 1998, Toyota releases the Genuine ATF Type T-IV Fluid Specification (JWS3309). This fluid was the Next Generation High-Performance ATF for Slip-Controlled Automatic Transmissions. This fluid replaces Type T-III, Type T-II and Type T fluids in all vehicles.

I guess Toyota spec'ed our transmissions with their own Toyota fluid Type T-III, is that right?
If so, I think Toyota Type T-IV does supercede the Type T-III, BUT I don't think an aftermarket Type T-IV necessarily meets the Toyota Type T-III spec. Hope I said that right.
I used 12 qts of off brand Dexron III during 3 drain and fills when I bought my tacoma. That was 3 years ago. And haven't noticed any I'll effects....yet.

 

Dexron II got replaced with Dexron III years ago
Just read the label and make sure the fluid is suitable for systems that call for Dexron III and earlier

Dexron IV and up are a completely different formula and should never be mixed. Do not put Dexron III in something that calls for IV and vice-versa.

I did the same and everything is still good

Says it is formulated to replace Dexron III on the back label, so you should be good with this
