I don't know exactly how the nissans work with their "limp" mode for what gear it goes into and such. This sounds like the computer is sensing a problem and going into the "limp" mode. Go get the code pulled to see what is says. If it has anything saying trans slipping or ratio problem then something internal in the the trans is wrong. Also, check the trans fluid and see if its burnt ( dark brown or black).

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).

Testimonial: "very detailed and useful response - beyond the initial question. Thanks"
Nissan Terrano's have an Electronic Computer that controls the gearbox. It is hidden behind the left hand rear Speaker box, right hard up against the rear seat back rest. This system controls all functions regarding the gearbox and it's rev rates. If your vehicle is shifting back on long drives then it is possible that the computer sees any slight increase in revs as a desire to "Kickback" the gearbox to a lower gearing, hence it dropping out of overdrive. Unfortunately a gearbox specialist with a computer "Plug-in" is needed to fix this, but it is fixable. This problem should not be too expensive in comparison with a new gearbox.
