New R34 owned here (from the US) and found a gem, '98 GTT with ~6k miles, super clean & completely stock.

When shifting there's no grinding, shifts smooth, etc. The concern I have are 2 things:

1) Only in 2nd and 3rd... when maintaining a slower speed (in traffic as an example) as I let off/on the gas, the shifter will slightly move and vibrate. If the clutch is engaged, none of this happens. It's not bad, but enough to feel like something isn't necessarily right.

2) This mainly happen in 4th or 5th... the shifter slightly bounces up and down, almost like it's riding on unbalanced tires (and I do think the tires are unbalanced as I get a little of that bounce feel at higher speeds, which is maybe why it only happens in 4th/5th).

Lastly, and sorry for this noob question but I want to work on this car myself, can someone teach me some on these manual transmissions? Like servicing them, best products to use, etc.; would be greatly appreciated.

Thanks!!

Congratulations on your find :) Did you mean it has 6k miles or was that a typo?

Firstly, keep in mind some movement of the shifter is normal...it is a long rod hanging out of a box bolted to the engine. Having said that there are 2 next places to look:

1. Transmission and engine mounts. If these are worn or broken the shifter will move around more. They are reasonably easy to source and replace on a hoist, and possible but uncomfortable to replace car stands

2. On the bottom of the shifter there is a nylon cup that sits over shifter's ball end. If this is worn or broken the shifter will move around more than it should (but will still shift OK). That is a cheap part and requires removal of centre console, rubber shifter hole covers and a circlip in the gearbox shifter hole to remove the shifter.

Re maintenance, as with any new import you should change all the fluids including transmission when you get it; never trust the seller and previous owners to have done the right thing. I am pretty sure R34 GTT is the same as earlier big box transmissions, so use any good quality GL4 75w90 trans fluid if it is shifting well (if it is hard to shift due to synchro wear, redline shockproof lightweight will keep it alive a bit longer before rebuild is required)

I'm going to have to call shenanigans on the 6000 miles. There haven't been any R34s with 10000km on the ODO since the mid 2000s. Photos of the pedal rubbers, seats, carpets, etc required to even consider the possibility. At that many miles the underside should look almost completely new.

The movement of the gear stick is likely to be 100% normal. As Duncan said, the differences from an auto may be surprising. It is a mechanical thing, not an electro-hydraulic isolation device.

Thank you both, much appreciated. Yes, 6k miles, not a typo lol. The underside, engine bay, engine, trunk, interior, etc., look great and super clean, has all the splash guards too. Not sure if you can expand the photos, but the dash pic shows the ODO. She looks brand new, inside and out, even has the original Nissan TV/DVD/Nav head unit; still thinks it's in Tokyo haha! I used to own a '94 MKIV Supra, sadly sold it years ago, but wow I love the Skyline so much! The R34 gets SO much attention here since they just became legal to import last year.

    • Can I suggest you try EBC directly again and link them to as many competitor catalogues as you can to show their listing is incorrect, eg https://dba.com.au/product/front-4000-series-hd-brake-rotor-dba42304/ If you have access to an R33 GTST VIN and your VIN, you could also use a Nissan Parts lookup like Amayama to show them the part number is different between 33 GTST and 34 GTT which may get their attention
    • So i got reply from EBC and they just this site where you can clearly see those 296mm fronts on R34 GTT. I send them photos and "quotes" that 296mm are not for 34 GTT and they are too small. But it will be very hard to return them cuz nobody here knows 100% and they just copy those EBC catalogue :-D https://ebcbrakesdirect.com/automotive/nissan/skyline-r34
    • Hi, is the HKS  Tower Bar still available ? negotiable ? 🤔
    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
    • Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.
