The 97-01 got 4auto/4high/4low. The V-8 4x4s all got a single-speed all wheel drive system. Although the system varies the duty cycle of the transfer case clutch, the clutch is mechanically either engaged or disengaged. The system is, essentially, 'rear-wheel-drive-until-it-slips'.
All-wheel-drive vehicles have more complex components. That means higher maintenance costs if something goes wrong. These added components can limit cabin space, as the rear floor has to accommodate a drive shaft. The added components are more of a draw on the engine, so AWD vehicles are typically not as fuel efficient.
for mixed snow and pavement, personally I would recommend 2hi with traction control. 4 wheel drive in a JT has no computer monitoring traction control at every wheel like an All Wheel Drive. It is purely mechanical. Its a different monster in the snow. Go to a nice big parking lot and practice.
Bring your vehicle to a speed of 3 mph (5 km/h) or less. Place the transmission in neutral (N). Move the 4WD control to the desired position. The information display can display a message indicating a 4X4 shift is in progress. The information display can then display the system mode selected.
The term quattro is Italian for “four,” which is appropriate given its association with Audi’s all-wheel drive system. Today, the Audi Quattro AWD system includes mechanical and electronic activation as well as intelligent software and sensors monitoring steering angle, traction, stability control, movement of the wheels, and yaw angle.
The difference between all-wheel drive, front-wheel drive and four-wheel drive seems more confusing than it actually is. Most modern cars are front-wheel drive, putting power to the wheels that are also steering the car. The same reasoning is applied to all-wheel-drive-equipped vehicles where power is distributed to all four wheels.
