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:

DSC06452_grande.JPG?648

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.

      My guesstimate, with no real numbers to back it up, is it won't effect it greatly at all.its not a huge change in position, and I can't see the air flow changing from in turbulence that much based on distance, and what's in front of it. Johnny and Brad may have some more numbers to share from experience though.

      Which solenoid? Why was it changed? Again, why was this done? ...well, these wear..but ultimately, why was it changed? Did you reset the idle voltage level after fitment? I'm just a tad confused ~ the flash code doesn't allude to these items being faulty, so in my mind the only reason to change these things, would be some drive-ability issue....and if that's the case, what was the problem? Those questions aside, check if the dropping resistor is OK ...should be 11~14 ohms (TCU doesn't throw a flash code for this) ~ also, these TCU designs have full time power (to keep fault code RAM alive), and I think that'll throw a logic code (as opposed to the 10 hardware codes), if that power is missing (or the ram has gone bad in the TCU, which you can check..but that's another story here perhaps).

      Question for people who "know stuff" I am looking at doing the new intake like the one in the picture (the pictured is designed for the OEM TB and intake plenum), this design has the filter behind the front bar, but, the filter sits where the OEM duct heads into the front bar, and the standard aperture when the OEM ducting is removed allows the filter to pulled back out of the front bar into the engine bay for servicing, a simple blanking plate is used to seal the aperture behind the filter This will require a 45° silicone hose from the TB, like the alloy pipe that is currently there, to another 45° silicone hose to get a straight run to the aperture in the front bar Question: how will it effect the tune if I move the MAF about 100-150mm forward, the red is around where my MAF is currently, and the green would be where it would end up Like this This is the hole the filter goes through  Ends up like this LOL..Cheers

      Despite the level up question, actually I do know what that is....it is a pressure sender wire.  So check out around the oil filter for an oil pressure sender, or maybe fuel pressure near the filter or on the engine. Possibly but less likely coolant pressure sensor because they tend to be combined temp/pressure senders if you have one. Could also be brake pressure (in a brake line somewhere pre ABS) but maybe I'm the only one that has that on a skyline.

      Pull codes via the self-diagnosis procedure. As far as I can tell this is just a sign of transmission issues but not a code unto itself.
