Adam- You can see the angle the G sensor is set at on a scan gauge with dash commander. Not sure how accurate it is as I didn't test it kn my car. My brother which has the exact same truck shows his forward back G sensor is set at -45 degrees but until he goes into Nissan and get it checked then...

Just got the truck back from a very very helpful Nissan dealer. First dealer the technicians actually knew more than me haha Had the gearbox oil level checked and it was 1.5litres overfilled. The oil in the box wasn't drained back after initial filling when brought up over 30degrees Celsius. So...

So I've done a fair bit of research and calling around. It is the same box as the 370z as stated but the TCM is completely different. It receives signal from the ECM reporting torque due to load. It changes the VGT (variable geometry turbo) and gear selected relevant to the torque required...

Sorry to bring up this thread but sounds like your issues could be related to the ecu pulling fuel to protect the gearbox. The jatco7r11e 7 speed sends load and torque signals to the standard ecu but can usually correct itself but allowing LU slip through the gear changes and even providing slip...

Blanked mine at the inlet side of the EGR pipe. Truck ran south smoother and a noticeable increase in fuel economy. If you pull the engine cover off you will see a ribbed silver pipe in the V of the engine on top. That is the EGR pipe. The side closest to the front of the car is the inlet to...

I'm going to have a look into that. Using UPrev to up line pressure, but ultimately trying to organize a controller for in cabin adjustment. Most NA 370's aren't getting any slip in the box but I notice a heap with the 550. Maybe the high torque. So I'm sure upping the pressure in anyway will be...

The pathfinder Ti550 uses the exact same set up as the navara 550. The hill descent control system uses the ABS to control the speed which in turn lets the gearbox hold gears. Maybe the pathfinder Ti550 drivers aren't too worried about the lag seeing as tr SUV is set up more for comfort on road...

There is some more technical info on the development of the box here including shift patterns, LU slip and how they use LU slip to make the box feel like a CVT box but remain conventional...

Hey guys, New to posting on here but long time reader of some very useful info. I've come to realise there is stuff all information about the 7 speed auto in the 550 navaras so I've decided to start at thread to open up some information to anyone that wants to know. First of all, this gearbox is...
