Transmission and Clutch Automatic Transmissions Service Intervals Check daily with engine idling. See Table 1, “Recommended Maintenance Intervals,” Page 154 for service intervals. Automatic Transmission Oil Level Preventive Maintenance NOTE: The vehicle must be parked on level ground. Maintain the oil level and check it daily. Oil should be up to the “HOT” mark on the dipstick when (1) the engine is running, (2) the transmission is at operating temperature, and (3) the transmission is in Neutral. See the Transmission Operator's Manual in the glove compartment for more information on checking the transmission oil level.

Preventive Maintenance STEERING AND DRIVELINE Power Steering Oil (under low pressure) provides the power to operate the steering gear. It also serves to lubricate moving parts and remove heat. A loss of steering efficiency will occur if too much heat builds up in the system. WARNING! Do not operate the vehicle if the steering system is not working properly. You could lose control of your vehicle if the steering system is not in good working condition, which could result in an accident causing death or injury. For driving safety, visually check the steering gear and components. Frequent checks are important for driving safety, especially after traveling over rough roads. NOTE: If the steering feels unbalanced from side-toside while turning, check for the following possible causes: • unequal tire pressures • vehicle overloaded or unevenly distributed load • wheels out of alignment • wheel bearings improperly adjusted Steering and Driveline If you cannot correct the problem, check with an Authorized Service Center. The Medium Duty vehicle is equipped with integral power steering. The system includes an engine-driven fluid pump, a fluid reservoir, the steering gear, and connecting hoses. Because of the hydraulic power assist, little effort is required to turn the steering wheel. When no input is applied through the steering wheel, the steering gear will return to the neutral position. If, for any reason, the power assist system goes out, steering the vehicle is still possible—yet it will require much greater effort. Visually check the following parts: • Crosstube: Is it straight? • Draglink tube clamp: Check for looseness or interference. • Ball joints and steering U–joints: Check for looseness. • Steering wheel for excessive free-play. Check the simplest probable causes first: – unequal tire pressures – loose cap nuts – bent crosstube – lack of lubrication Medium Duty (R05/09) Y53-6027 – 243 –
