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.

    • Haha, i kow right? Could have bought so many cars for the same amount of money (or less) but driving Unicorn gives you at least +1mln to style 😅. Like wise man said "life's to short to drink cheap wine and drive boring cars" 😉
    • Newbie here, proud owner of an Autech 260RS. I'm on the hunt for wiring diagrams specific to the 260RS, particularly S1. I've ran my eyes through R33, R34 Diagrams, there are some similarities, however continue to find incorrect wire colours and pins on connectors in the 33,34 diagrams.   I was hoping someone could point me in the right direction? I'd be happy to pay for the originals in Japanese. I can translate them, at least they would be accurate.   Any help please would be greatly appreciated, never heard an RB26DETT before let alone driven one, and I've got a spaghetti monster of goodness to sort out.   Cheers Benny  
    • Hey all  im wondering if you can help me please I have put a rb20 box in my r34 gtt as my auto packed up and a friend had a spare box I know it’s not ideal but it will get me up and running for now. we have done the conversation and everything is working great but my Speedo we got a s13 speed sensor but my Speedo reads double now and I bought a speed converter but still not having any luck.  so I thought I’ll reach out and pick your brains  any help would be appreciated please as I wanna drive my car again 
    • Drain it. I got official Matic D but you can get whatever is listed as Matic D compatible.
    • Thanks guys,  Yeah I should at least have them dynoed, at least then I know what I've got as a starting point.  The springs on these are hard as rocks. I vaguely remember Russman saying he was going to sell the shocks to me with the rocks fitted, as he was keeping the softer springs for his new setup.  I didn't click at the time but of course that was to let me know the shock/spring wouldn't be matched.  I also remember pricing up new springs around 2014-15, but, house, money etc. it never happened. So that was another reason to have them rebuilt. I have rebuilt the forks on many motorcycles so I think I could handle the seals on these easily enough, but getting the valving right would be a rabbit hole I cbf exploring.  Duncan, interesting to hear RP was tuning these back then. I might give them a call.  In the mean time I have been busy fitting sway bars. The Whiteline rear sway bar I purchased 15 years ago finally got fitted, along with the Whiteline front bar that showed up last week. Just waiting on new links for the front sway bar to finish that off.  And my spare set of advan AVS VS5's should be back from the powder coaters in a Pearl White finish sometime this week, with a set of Hankook RS4's lined up for fitting.  And then I just have all the suspension bushes to do. A comprehensive kit is on the way... Lots to do before the Ararat hill climb. Cheers guys 🍻
