Has any tried Castrol Transmax E in their 2006 D40 Auto Transmission as yet?

Welcome Mark. Can't say I've heard it mentioned here before (doesn't mean it hasn't been though), we touched briefly on transmission fluids in one of the oil threads but I don't recall what they were.

Hi KarftyPg,
It's the tramsmisson fluid recommended by Castrol for Transfer cases & Auto Transmissions for the Navara's. I was just wondering if any one has tried it, and if so what the feel in the gear changes might be - if any.
It's a new fluid that supersedes the Transmax Z.

Doesn't appear like there's been many try it, but a bump up to the top of the list might get some new readers.
Nissan are super-pedantic on the ATF. The manual states ONLY their oil is to be used. They will probably try to avoid any warranty issues if some other oil is in the box.
The big problem with different grades of ATF is that the torque converter is designed around a specific grade and mix of oil.
A lighter oil will allow the torque converter to slip more, so you lose more revolutions of the engine (less efficient), but gear changes should be smoother.
A heavier oil will make the torque converter grab harder, turning the gearbox over more for each engine revolution, but gear changes won't be as smooth.
That balance is the key, and because there are so many widgets inside the gearbox, it really does need to be kept fairly close to spec.
I've had my 40K service done, the ATF was good so it was left intact. We just got back from a 7,000km christmas trip (posting details on this soon) and the gearbox performed wonderfully, not missing a beat - again, I'm on the standard Nissan ATF.
That's not to say that "standard Nissan ATF" isn't made by Castrol and might even be the oil you're looking at - they gotta get it from somewhere!
