Eaton has revised its Lubricant Suppliers List (TCMT0020 EN-US), which lists suppliers of approved fluids that meet the new PS-386 specification.
The Lubrication Guide begins with "Important Eaton Transmission Lubricants Update", as follows:
- Eaton transmission lubricant specification PS-164rev7 has been replaced by PS-386. All applications that required the use of PS-164rev7 approved lubricants will now require the use of PS-386 approved lubricants.
- Eaton makes a note that All major OEMs have transitioned to the PS-386 approved lubricants.
- Eaton also states it recognized a transition period until PS-164rev7 oils were eliminated in the market. Effective January 1, 2017, warranty coverage requires PS-386. Both PS-164rev7 and PS-386 oils can be mixed. Top offs using either fluids are permitted.
In this guide, Eaton also announces the introduction of Procision Transmission Unique Lubricant Specification PS-278, the only approved lubricants that are acceptable for use in the Procision transmission. Eaton notes that PS-278 approved lubricants are the only acceptable lubricant for the Procision transmission. NOTICE:Do not use PS-278 oil in other Eaton transmission models or damage may occur.
Eaton makes a special note: "To avoid damage to vehicle, never mix engine oils and synthetic transmission oils in the same transmission. When switching between types of lubricants, all areas of each affected component must be thoroughly drained. Do not introduce additives and friction modifiers. Do not mix lubricants of different grades. Do not mix mineral and synthetic lubricants. Do not mix heavy-duty, multi-purpose lithium based (#2 grade) grease with Sodium based grease."
