Frequency of fluid and filter changes are determined by the severity of the transmission application. More frequent changes are necessary when high levels of contamination, overheating, or S O S oil analysis indicates that the transmission oil has been contaminated. Contamination may include a viscosity change, a strong odor, S O S high levels of iron, aluminum, silicon or other elements, or a discolored black appearance.Note: During a system failure of internal components, the power train generates abrasive debris that circulates throughout the system. The debris can cause the valves, the power train, pumps, and actuators to suffer repeat failures. Thoroughly clean debris from the system after a component failure and replace the transmission oil cooler core in order to prevent repeat failures. Refer to Operation and Maintenance Manual, SEBU6250, "Caterpillar Machine Fluids Recommendations" for information on improving the durability of machine components and for additional fluid information.When a maintenance interval has been reached, all of the specified maintenance for that particular interval must be performed.Fluid RecommendationsThe Series CX of on-highway transmissions are designed to operate with ATF fluids that meet Caterpillar "AT-1" or Dexron® "IIIH" specifications. Extended oil change intervals require synthetic oils meeting Caterpillar "AT-1" specifications. Caterpillar ATF synthetic oil is available through Caterpillar dealers. Refer to the Operation and Maintenance Manual for oil change intervals based on applications.Note: Do not use Caterpillar "TDO-4" oil in the Series CX of on-highway transmissions.Application Severity DefinitionsSevere Application vehicles operate both on and off highway. The following applications are typical applications: dump trucks, transit mixers, refuse trucks, all wheel drive public utility trucks, snow removal, yard spotters and concrete pumpers. Heavy equipment transport and special PTO applications are also considered severe applications.General Application vehicles operate exclusively on paved or improved roads. The following applications are Typical applications: line haul, pickup and delivery, beverage delivery, public service dump, emergency vehicles and recreational vehicles with living accommodations.Note: Caterpillar recommends the CX28 main transmission filter be changed after the initial 200 hours of operations.
