Lubrication Requirements and Specifications
Eaton UltraShift PLUS PV Transmission Gear Box Lubrication Requirements
Eaton requires the use of a transmission lubricant that meets PS-164 rev 7 specification.
A list of approved lubricants and suppliers can be found in the Approved Lubricant Supplier Manual, TCMT0020.
Not using the required lubricant will result in degraded performance and shortened life of the product. Refer to the Lubrication
Manual, TCMT0021, for the latest information regarding lubrication requirements.
Note: Eaton recommends the use of Eaton Roadranger Lubricants. Roadranger SAE 50 Synthetic Lubricant and Eaton PS-164
rev 7 are the only approved synthetic lubricants.
Note: Failure to adhere to Eaton installation requirements may affect the transmission performance and / or warranty coverage.
Warnings and Cautions
• Before working on a vehicle, place transmission in neutral, set brakes, and block wheels.
• Do not introduce additives and / or friction modifiers. Additives of any kind added later to the oil can result in
unpredictable consequences. No liability of any kind will be accepted by Eaton for any damage resulting from the use
of such additives.
• Do not mix lubricants of different grades.
• Use clean containers when transferring lubricant from the bulk storage to the transmission. Containers used for
antifreeze or water should be cleaned prior to use.
• Do not re-use lubricant.
• Failure to use the required lubricant will affect the transmission performance and the warranty coverage.
• SAE 15W-40 viscosity grades are not allowed in Eaton transmissions.
Operating Temperatures
Transmissions must not be operated at temperatures above 250 °F (121 °C.) Operation at temperatures above 250 °F (121 °C)
causes loaded gear tooth temperatures to exceed 350 °F (177 °C) which will ultimately destroy the heat treatment of the gears.
The following conditions in any combination can cause operating temperatures over 250 °F (121 °C.)
• Operating consistently at high loads / slower speeds
• High ambient temperatures
• Restricted air flow around transmission
• Exhaust system too close to the transmission
