ATF questions

[Hennie Marais]

I searched through most of the ATF treads but would like to get a little bit more info on some of the oils and problems. What I've read here:

1. Do not use Dexron III, looks like it makes the gearbox slip. What's the reason for this or is it just an additive in the oil causing the problems.

2. Read transmax Z is a killer too, I see it's full synthetic but I'm not sure if that's the reason

3. Transmax J is part synthetic and some say it can be used.

4 Transmax M - mineral oil ,universal ATF. I could not find anyone trying this, any comments on it.

5. type II and VI, what makes the oil so special?

6. what's the biggest problem with modern oils in the A341, is it the full synthetic oil not working with it, additives in it, etc. I'm trying to see were the problem lies?

I see Mobil ATF 3309 gets highly recommended by some for the lexus.

Went to toyota to buy my type IV ATF, guess what, they only stock one that says "recommended for all toyota transmissions" and with it in big red letters "Dexron III". Now how's that possible, there's no type 4 here.

ahhh, found some Type 4, sad it's in another city.

From my experience I find the transmission shifts harder with the Type T 4 . especially if you sift from P to D you will feel the jump ​

Hmm, that might be a good thing with my turbo setup.

Hennie,
Where did you find type 4 oil?
