SHUT-OFF G. 3D4215 - Caterpillar

If the ambient temperature at engine start-up or during operation is below -10°C (14°F), perform the procedures in Operation and Maintenance Manual, "Machine Warm-Up". Check the transmission for the proper fluid level. Failure to warm-up the oil or improper lubrication levels prior to operation will cause damage to the transmission.
Caterpillar MTO 10W30 is balanced in order to provide maximum friction material life in the following components: power shift transmissions and torque converters. MTO 10W30 has passed the requirements for the MTO 10W30 oil specification. The MTO 10W30 oil specification includes frictional requirements and gear wear requirements.Caterpillar only recommends Caterpillar MTO 10W30 oil. This oil provides the maximum performance and the maximum protection for Caterpillar transmissions.Note: Multigrade oils must meet the requirements of Caterpillar MTO 10W30 for use in transmissions. Multigrade oils that use high molecular weight polymers as viscosity index improvers may lose the viscosity effectiveness because of temporary shear and permanent shear of the polymer viscosity index improver. These types of multigrade oils are not recommended for Caterpillar transmissions. The Caterpillar MTO 10W30 oil requirement includes a test for the shear stability of multigrade oil. If Caterpillar MTO 10W30 is not available, use commercial oils that comply with Caterpillar MTO 10W30 oil specifications.Note: Refer to Operation and Maintenance Manual, SEBU5898, "Cold Weather Recommendations" for the selection of oil when the machine is operated below −20 °C (−4 °F).
