Sorry mine is 2004 model with 70000k on it was due for first service so i was going to change all the oils . Was doing a bit of reading and some people are suggesting castro transmatic j is a exact same thing so i thought i might ask you guys first . But cheers !

Go to Jetwreck (Craig'S) workshop and get a Transgo kit installed, almost all the trans fluid is dropped during fitment, it's the best way to ensure the fluid and filter are clean, and your gearbox will love you.

If it is Matic J compatible, it will be fine to use (as will any other fluid that is Matic J compatible)

Would the transgo kit increase wear on the gearbox since the shifts are quicker?

Slower shifts cause more wear, but manufacturers opt for slower shifts because consumer usually want smooth shifts.

No.

The part throttle operation of the box is identical. It still shifts smooth.

On full throttle it shifts faster without the slurrrr.

The only harshness I've had is when the box kicks down itself to 3rd. Does it with quite a clonk. Benefits over weigh negatives massively.

Go for a ride in one. You'll see.

As Alex mentioned, the shift kit fixes the mechanical side of the shift, but the auto ecu is still an issue. Sometimes at full throttle the gearbox will shift hard but the engine isn't on power yet, this can cause a slight clunk. It doesn't happen very often.

At light load the shifts are quite gentle.

There’s a lot of products out there that have replaced Nissan Matic J, for example you can use Penrite Multi Vehicle Full Synthetic ATF FS which is a new formula of transmission oil that specify for many other vehicle makes as well.

    • I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.
    • You are all good then, I didn't realise the port was in a part you can (have!) remove. Just pull the broken part out, clean it and the threads should be fine. Yes, the whole point about remote mounting is it takes almost all of the vibration out via the flexible hose. You just need a convenient chassis point and a cable tie or 3.
    • ..this is the current state of that port. I appreciate the info help (and the link to the Earls thing @Duncan). Though going by that it seems like 1/4 then BSP'ing it and using a bush may work. I don't know where I'd be remote mounting the pressure sender... to... exactly. I assume the idea here is that any vibration is taken up by the semiflexible/flexible hose itself instead of it leveraging against the block directly. I want to believe a stronger, steel bush/adapter would work, but I don't know if that is engineeringly sound or just wishful thinking given the stupendous implications of a leak/failure in this spot. What are the real world risks of dissimilar metals here? It's a 6061 Aluminum block, and I'm talking brass or steel or SS adapters/things.
    • And if you have to drill the oil block, then just drill it for 1/4" and tap it BSP and get a 1/8 to 1/4 BSP bush. The Nissan sender will go straight in and the bush will suit the newly tapped hole. And it will be real strong, to boot.
    • No it doesn't. It just needs an ezy-out to pull that broken bit of alloy out of the hole and presto chango - it will be back to being a 1/8" hole tapped NPT. as per @MBS206 recco. That would be for making what you had in alloy, in steel. If you wanted to do just that instead of remote mounting like @Duncan and I have been pushing. A steel fitting would be unbreakable (compared to that tragically skinny little alloy adapter). But remote mounting would almost certainly be 10x better. Small engineering shops abound all over the place. A lathe and 10 minutes of time = 2x six packs.
