I have had this short 'grinding' noise intermittently for several months. Low speed, first gear, once or twice low speed second maybe?

I have only used LC2 a couple of times (no not understating to protect myself)

Anyone else had this here?

Taking car to Nissan prior to next track day.

lol whats FWIW stand for, i cant work it out.

Just sounds like that its a pretty rare issue at this point in time, probably one of those things that happens to every car model, there are so many things that can go wrong that its amazing that the r35 has such few things that are actually failing on them, thje more parts and gizmos in a car, the more chance that something can go wrong.

Don't worry about it untill it happens to your car or you will always be paranoid looking for something to break

the GR6 transmitions not very smooth at low speeds but several R35s already have transmition problems like while they are still new and not even driven hard. have your tranny checked, hopefully its just the normal operation. we do have customers coming in complainin about some rattly or grinding noise before as well.

this occured with oem fluid long before the pentosin went in. havent had it since (you can work it out by dating this topics post date and the pentosin post date).

The transmission is actually a bit quieter and smoother with the pentosin in for what thats worth.

proof will be in how it holds up to the 10,000 road km use and 1,200 track km per year over the next year or so if the tanny lasts that long.

the car is a 2009 model.

I have had a slightly different noise when changing from first to second. There is a bit of a clunk noise from the gear box. It is not a gear clunck, it it more like a sound of metal hitting metal for a split second. I hear it more when travelling through tunnels or when the sound bounces of surrounding buildings, it is more pronounced under hard acceleration.

I havent had any grinding noises but FWIW whilst there is no doubt the Willal oil is the best track solution, and still beautifully smooth on the shift, my car (tranny) shudders like a bucking bronco off the line in daily driving. I'm thinking about going back to Nissan oil for a while to see the difference...

that sounds like gearbox/engine mounts to me which makes no sense as they usually take a while to give up

      Magnetic Drain Plug Snapped in Half

      By kevboost7 · Posted

      Update: I got the magnet out. I bought 3 different flexible magnetic reach tools, but none of them worked. The magnet on the tip was all less than 2lbs of force, so i had to buy a special cylindrical magnet that had a pull force of 9lbs.  The magnet finally came in the mail yesterday, so i got under the car to get to work. The super strong magnet isn't that long, so i only have about 1 finger pinch lengths to hold it. I was so scared when i was going in the hole, that the 9lb magnet would just fly away inside the oil pan never to be seen again, but i had my butt cheeks clenched and finger gripped on that thing so tight, i managed to get it to suck the other magnet out.  It was a victory for me last night.

      New fix for low tyre pressure from bmw

      Yep, pretty much what you said is a good summary. The aftermarket thing just attached to the rim, then has two lines out to valve stems, one to inner wheel, one to outer wheel. Some of the systems even start to air up as you head towards highway speed. IE, you're in the logging tracks, then as speeds increase it knows you're on tarmac and airs up so the driver doesn't even have to remember. I bet the ones that need driver intervention to air up end up seeing a lot more tyre wear from "forest pressures" in use on the highway!

      Anyone know this frontpipe?

      By sunsetR33 · Posted

      Yes, but you need to do these type certifications for tuning parts. That is the absurd part here. Meaning tuning parts are very costly (generally speaking) as well as the technical test documentation for say a turbo swap with more power. It just makes modifying everything crazy expensive and complicated. That bracket has been lost in translation many years ago I assume, it was not there.

      Hahaha, yeah.... not what you'd call a tamper-proof design.... but yes, with the truck setup, the lines are always connected, but typically they sit just inside the plane of the rear metal mudguards, so if you clear the guards you clear the lines as well. Not rogue 4WD tracks with tree branches and bushes everywhere, ready to hook-up an air hose. You can do it externally like a mod, but dedicated setups air-pressurize the undriven hubs, and on driven axles you can do the same thing, or pressurize the axles (lots of designs out there for this idea)... https://www.trtaustralia.com.au/traction-air-cti-system/  for example.... ..the trouble I've got here... wrt the bimmer ad... is the last bit...they don't want to show it spinning, do they.... give all the illusion that things are moving...but no...and what the hell tyre profile is that?...25??? ...far kernel, rims would be dead inside 10klms on most roads around here.... 😃

      You're just describing how type certification works. Personally I would be shocked to discover that catalytic converter is not in the stock mounting position. Is there a bracket on the transfer case holding the catalytic converter and front pipe together? If so, it should be in stock position.
