Maximum Recommended Downshifting Speeds Gear Selection Maximum Speed 1st 2nd 3rd 4th 5th Manually Shifted Transfer Case Operating Information/Precautions The transfer case provides 4 mode positions - 2 (rear)wheel-drive high range, 4-wheel-drive high range, neutral, and 4-wheel-drive low range. This transfer case is intended to be driven in the 2-wheeldrive position (2H) for normal street and highway conditions such as dry hard surfaced roads. When additional traction is required the transfer case 4H and 4L positions can be used to lock the front and rear driveshafts together and force the front and rear wheels to rotate at the same speed. This is accomplished by simply moving the shift lever to the desired positions. The 4H and 4L positions are intended for loose, slippery road surfaces only. Driving in the 4H and 4L positions on dry hard surfaced roads may cause increased tire wear and damage to the driveline components. 10 mph 19 mph 32 mph 50 mph 68 mph (16 (31 (51 (80 (109 km/h) km/h) km/h) km/h) km/h) FOUR-WHEEL- DRIVE OPERATION - IF EQUIPPED Four-Wheel-Drive Dodge Ram Trucks are equipped with either a Manually Shifted transfer case or an Electronically Shifted transfer case.
