MAINTENANCE - Vehicle Towing operating angle is the transmission mounting angle in the chassis plus the percent of upgrade (expressed in degrees). interval should not exceed 60,000 mi / 96,000 km / 6 Months. NOTE Before checking the oil level, the en- gine must be idling and the transmis- sion in neutral for at least 2 minutes. Lubricant temperature must be be- tween 60 °F and 120 °F (15.5 °C and 48.8 °C). Transmission Lubrication Change Intervals Lubricant changes should be based on a combination of the intervals shown in vehicle operator manual Lubrication Specification Manual, and user judgment based on the application and operating environment.
Extending drain intervals beyond those shown in the tables is not recommended and will put warranties at risk. Inspect the transmission exterior for leaks. Look around the oil filter and exterior seals for damage and replace as necessary. Vehicle Towing When towing the vehicle, the output shaft of the transmission must not be allowed to spin or turn. If the vehicle is towed with the drive wheels still in contact with the road surface, the vehicle axle shafts or driveline must be removed or disconnected. 3 CAUTION Always follow proper manufacturer towing procedures. Failure to follow proper towing procedures could result in damage to the transmission.
On-Highway Check fluid levels and inspect for leaks at regular PM maintenance intervals, not to exceed 12,000miles. Drain and replace lubricant every 500,000 miles / 800,000 km. How to Drain Fluid Off-Highway 1. Use a drain pan under the transmission drain plug to collect oil from the bottom of the transmission. If the transmission operating angle is more than 12° (or roughly a 21% grade), improper lubrication will occur. The Check fluid levels and inspect for leaks every week.
