• Transmission and clutch lubrication specifications

Transmission Lubricants

Eaton recommends the use of Eaton lubricants for an extended drain interval.

Use the Heavy-Duty and Medium-Duty charts, starting with transmission type, to locate the correct lubricant and change interval.

Note: See line haul and vocational definitions for more information.

Transmission Oil Filters

Transmission filters should be changed during regular lube intervals.

Inspection of the transmission filter should be conducted during preventative maintenance checks for damage or corrosion. Replace as necessary.
