Got this message back from Castrol this afternoon:

Hi Matthew,

Thanks for the follow-up email.

The Transmax E had to be formulated last year because the additive
required to blend the Transmax J was no longer available. The
performance of the Transmax E is equivalent to the Transmax J in some
parameters but better in areas including; friction durability, torque
capacity, wear protection and oxidation stability.

I can confirm that Subaru are now using this product at their
dealerships though I don't know if their auto transmission are brought
into the country filled with a different product.

I hope the above information proves valuable.

Regards,
Dimitrius

So from the sound of it, the Transmac E which is what Subaru is now using is a better fluid when compared to Transmac J, which is what they used to use.

I might add, it is not recomended by Subaru to mix these fluids... So if you're thinking about changing, you need to have a transmission fluid flush... This generally happens at major services (EG 45,000kms).

So if I was to change to another type of fluid... What do I need to keep my eye out for? I don't want to have a repeat of what happened with my mates Polo... I want to be "sure" that what I'm doing is going to give me a genuine advantage over what Subaru offer

Just going by what I was told. You definitely can't use DEXRON III in it, and I was told that the Castrol/Subaru stuff is the only stuff it's designed to work with.

As you can see from the responses I got from Castrol, that seems to be exactly what they are suggesting.

I'm going to look into Redline products a little more as it has been recommended to me by more then one person.

Oh, also, it would appear that people running the 4sp auto's may have a little more choice in regards to fluids - Shano you lucky bugger!

I spoke to Redline this morning & they will be getting back to me with a product that can be used in the 5sp auto's safely They wanted to cross reference their products with the Castrol products (Subaru OEM) to ensure they will not cause any dramas

Damn you people with 4sp auto's, you've got it nice & easy

& for info, "Smurf Blood" is a Redline manual transmission fluid product.

Out of interest, are there any other companies that I should be contacting?

Castrol has been done, now I'm onto Redline (Which is very highly rated)... Any others?
