Question about 1990 Nissan Pathfinder

Open Question

Purpose of switch on dash of Terrano R3M (auto transmission).

This is on the dash in front of the driver, it has three positions, 'HOLD', 'A/T' and 'POWER'.

I understand 'Power', but what else does this switch do?

SOURCE: Front wheels not moving in

The grease seeps out when the seal is worn out or defective. In your case it appears it's defective: a bearing in the front differential broke, it locked the wheels and damaged the seal.
Repairing it will be a big job: you will have to completely dismantle the front differential. In the mean time disconnect all the shafts to it and use the truck strictly as an 2WD.

Cant get motor out of 4x4 nissan terrano r3m got i all apart but no room to get out so is there some trick got all the bolts out from the gear box sump hits front diff can you help many thanks

Does this vehicle have the bottom crossmember running from the front to rear that holds the mounts like most nissans, if it seems difficult you can always rest it on the ground from the bottom then pull it out, its just a lot easier for me that way

Engine removal

There is a device that you can put on the hook and there are too chains down to the lifting points of the engine The hook point can be screwed back and forth allowing the engine to tilt down at the back and the angle achieved will allow the engine to clear any problems . You can achieve an angle of lift up to 60 degrees safely. When refitting the engine as you put the engine in as you lower the engine you can alter the angle to glide it in and up to the gear box flange perfectly

My nissan terrano r3m 91 model has a EXCLAMATION icon with in a circle on the dash that stays on red light it used to turn off once i put down the handbrake, now it stays lighted After I Drain some excess...

I dont think they both use the same waring light, check the switch on the handbrake, and make sure its connecting and turning off correctly, could be a bent or broken bracket.

1996 Nissan Terrano diesel automatic. How and when can you change High to Low ratio? What does the toggleA/T button, which has 2 seetings - power and hold, do? What does the dial which has 3 positions -...

High to low /low to high ratio, you will need to be stopped and the transmission in neutral for this to be changed.
The 2wd - Auto - Lock switch can be switched at any time, as it operates an electromagnetic clutch - 2wd is rear wheels driving only - Auto - is to automatically engage 4wd when wheel slippage is detected (this also happens when turning at intersections, due to the inside wheels having a shorter path to the outside wheels, and can give a binding effect on sealed roads (I don't drive with it in auto on sealed roads) auto is excellent if you get, or expect wheel spin from an intersection when wet, just flick it on before or when you have wheel spin, also on gravel roads, having it on auto will greatly reduce the sliding of the back end, and make the car noticeably more stable.
Lock - this locks the differential, which further reduces wheel spin, when in mud / snow, but this will also make the car not want to turn corners, due to it resisting the different distances traveled by the inside and outside wheels.
A/T switch - this actually has 3 positions, and changes the shifting points of the automatic transmission - the middle is normal - Hold is to hold the gear longer, to improve fuel economy, and not change down (kick down) as quickly - Power has the opposite effect, it makes the transmission change down sooner under acceleration.
Also the O/D (overdrive) button on the side of the Tee shift lever, is to engage / disengage overdrive (5th gear) - never do heavy towing in overdrive, this will cook the transmission and overheat the engine (due to the radiator being used as a heat exchanger for the transmission fluid.
Another little quirk - if the transmission light starts flashing every 40 to 50 km, this can indicate that the wheels are different diameters (a flat tyre, or tyres have been swapped around and the spare is more or less worn than the other tyres), the computer will pickup that the wheels are turning at different speeds.
When cold, it is normal for the transmission to stay in 3rd (2-3 minutes of driving), until it has warmed up, and then stay in 4th for a few more km's (5-6 minutes), before it has warmed up enough to change into 5th (overdrive).

Check transmission fluid after driving for a while, this could be down a bit. If 4 wheel drive, make sure it's in 2H.
