So drove down the southern highlands from sydney today. On the way home near heathcote, car suddenly feels like its losing power and I get a TCM error.

Pull over and restarted the car cool down and tried restarting but still had the error. Had my Cobb on me but for some strange reason, after plugging in, it just loads the AccessPort screen.

Anyways, realised the car only had 1,3 and 5 gear and was in limp mode (I think) as it feels the car limited my speed to under 40 km/h.

Will be taking it to the workshop on Monday (out of warranty and cobbed so doubt Nissan will like that) but from reading, I suspect it could be a solenoid or sensor. Though it obviously could be something more serious =(

If you have had the issue before, could you shoot me a PM please =)

Thanks

if it was something major the car wouldn't be driveable

most likely pressure sensor or solenoid

either way nissan dealer wont attempt to trouble shoot beyond ecu codes, their suggested and only fix will be a replacement trans - dealers aren't mechanics

best put the car on a truck and send it to willall

Most probably pressure sensor fail...same problem I had.

Dont bother will Nissan...if your car is modded they will diagnose then charge you to say they cant help.

If you want to transport your car to Willal in Adelaide by someone who cares about your car let me know

They managed to pull the codes using their AP but I didnt ask them what they were as I was flat out today. I'll ask them tomorrow but they mentioned they got the usual plus one they haven't gotten before.

They also cleared the codes and it drove fine again for a bit. Then they went from 5th to 6th and the the transmission oil pressure shot up to double and the the t/m malfunction and limp mode came back on. I'm assuming this is pressure sensor or related.

In any case, the gearbox is coming out tomorrow to get fixed.

P2832 - Shift Fork 'A' Position Circuit Range/Performance

Solution for the aftermarket appears to be the TSB Clip (assuming your car is 2011+).

Taken from 'Jacks Transmissions': ( http://www.jackstransmissions.com/pages/gtr-gr6-clip-tsb )

The shift pistons in the valve body make contact with the forks and move them into position. If these pistons wear, the forks and sliders will no longer shift properly and can be damaged. This is a common problem with the GR6. Prevention is to perform this TSB.

We have never encountered these problems again after performing this TSB so it has become standard procedure to install clips in every unit we touch.

APPLIED VEHICLE:2009 – 2011 GT-R (R35)

For 2009 - The MIL is on and DTC P0729 (6GR Incorrect Ratio) is stored,
For 2010 - The MIL is on and DTC P0729 (Sleeve A1 Function) is stored,
For 2011 - The MIL is on and DTC P2832 (Shift Fork A) is stored,


Here is a picture below of the wear. Note the circled area. It doesn't look like much, but that is enough to cause thousands of dollars in damage:

The clips will allow for better contact with the piston and prevent the wear or failure.

There are a series of magnets inside the piston which will become out of range of the sensor if the assembly wears too far. This will prevent the system from recognizing where the piston is moving and the unit will shift the fork too far as it doesn't know the forks location. This is what will break the fork along with the slider. This simple TSB solves any issue you could ever encounter with the fork or sliders. Well worth performing while you have your pan out and this TSB can be completed while the trans is in the vehicle.

    • It's excellent but I'm still breaking it in so I'm not 100% sure where it'll end up. I would say it's about 15% heavier than stock and the smoothness of the slip zone is quite progressive but you need to be a little patient compared to stock or it'll bite hard and stall. Stock I got away with absolutely horrid clutch control. Like I said before I couldn't even tell where the clutch would grab when it was stock so releasing way too quickly without enough revs it would just slip and the revs would drop lower than ideal but that would be the end of it. Currently there's a bit of a nasty clutch judder if I don't apply enough revs + find the exact wrong point of the slip point in the clutch pedal but it feels like it's slowly resolving as I drive it more. I would not recommend the competition clutch unless you really need the extra clamp force. I think this clutch combined with the Nismo operating cylinder is going to be exactly what I want. Enough bite that you need to remember the release point to avoid stalling or rough shifts, but progressive enough that it's not hard to drive by any means and not heavy at all. I tried a "super single" clutch on my friend's 997.2 Turbo 6MT and that was absolutely horrid. It runs an electrohydraulic power steering pump for the clutch power boost so there's zero feedback in the clutch pedal and there was a horrific clutch shudder well after break-in due to the lack of marcel springs or hub springs in the friction disk. It felt like the slip zone was the thickness of a single toe twitch as well so it was almost impossible to avoid stalling it unless you gave it a ton of revs and just dumped the clutch instead of trying to be smooth with it. I was terrified of pulling out in front of traffic. I have also tried some kind of "super single" on an EK9 and that makes this twin plate Coppermix look like a stock clutch. Releasing the clutch pedal even slightly too quickly feels like you're getting rear-ended. The pedal is extremely heavy as well and there's no vacuum assist like the GTR.
    • Yeah, well I was probably way underguessing the $300 figure anyway. Just multiplied a "normal" by 4 for the purposes of pointing out it's not cheap, particularly if it has to be repeated.
    • We have an alignment shop out here that does what you're talking about but he wants like 800 AUD a pop. DIY is "cheaper" but once you start accounting for the value of your time I'm not sure it's worth it.
    • The main catch phrase for any car is "the eye of the beholder", and "personal tastes and preferences" And as for the plastic "flares", I honestly think they look cheap and tacky, and I cannot see them aging well, maybe if they were body colour they might look better to my eyes, but, I would still prefer it the were more like the older WRX STI models that had the wider body metal panels In saying all this 5hit, I wouldn't buy a new WRX again, even if it had the wide body metal panels
