Transfer case as in gearbox? That was fully flushed recently.

Checked the Attessa, the reservoir is actually quite overfilled. Planning to get it flushed with Nulon Synthetic tomorrow anyway, is there a drain plug or something that you open? Will get the diffs done as well.

I think I have a random leak that isn't oil which I'm getting them to look at also. I thought it was power steering but the level in the reservoir seems okay.

So I had the diff oil changed (new diff oil) and the attessa and transfer case changed (Nulon 100% synthetic) and the problem is fixed. Good call Scotty!

Incidentally the leak turned out to be a hole in my radiator top tank which I discovered on the way to work today :rolleyes: yay!

There is Matic J in the transfer case also, as well as the gearbox. ;)

The power steering can also cause bad shuddering if it gets air in the cylinder.

The service manual says Matic J in the gearbox (10.3 litres) but Matic D (1.8 litres) in the Transfer case.

Something I'm not clear on though is the atessa fluid, is this the transfer case oil or separate to it? I'm having the same shudder problems as the OP.

I have Nulon synthetic in the power steering, the attessa and the transfer case without issues. The gearbox will have standard Dextron III in it when it comes back from Kewish, they prefer non synthetic fluid for some reason in their rebuilt auto's.

The transfer case has a simple 10mm allen key drain bung, it is separate from the attesa fluid. Make sure you crack the filling bung first. ;)

Yes, and Matic D for the Attessa.

The easiest way is just to use a fluid that is compatible with both Matic D & J in everything - hence the use of Nulon 100% synthetic trans fluid.

      S1 Autech 260RS Wiring Diagrams

      By ARB26 · Posted

      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

      Drain it. I got official Matic D but you can get whatever is listed as Matic D compatible.

      Tein Circuit Master- rebuild worth it?

      By QB6SAGR · Posted

      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 🍻
