1. Follow fluid and filter rules set by the transmission manufacturer. Many transmission failures can be avoided with adherence to service schedules.
2. Transmission fluid cools, lubricates and transmits hydraulic power. Too little fluid and the torque converter, bushings, bearings and clutches will not receive an adequate supply of oil. Too much oil can cause it to aerate, resulting in overheating.
3. Oil leaks primarily occur around the side of the transmission casing, external oil cooler or where power take-off points are located. Check these points frequently.
4. Try to keep a transmission free of contaminants. Solid foreign bodies have a detrimental effect on bushings and roller bearings.
5. Driveshaft components, the oil cooler, and transmission filter regulator should be examined at 25,000 mile intervals.
6. Check fastener tightness. Bolts with an incorrect torque can cause vibration. Stripped threads may lead to transmission removal for main case replacement.
7. Check electronics and wiring harnesses as part of an inspection.
8. Have crane operators report potential troubles such as odd automatics shifts, fluid leaks and unusual noises and take action to avoid downtime.
