Eaton Fuller 10-Speed FAQ
What's the difference between a Super 10 and a standard 10-speed?
A standard Eaton Fuller 10-speed pairs a 5-speed main box with a 2-speed range (Hi/Lo) selector, giving the familiar double-H pattern; gears 1–5 in low range, then flip the range and run 6–10 in high. A Super 10 (RTO model) instead uses a push-button splitter with single-lever sequential shifting and no range lever.
What oil does an Eaton Fuller 10-speed take?
Eaton recommends 50-weight synthetic transmission oil (such as PS 386), and most 10-speeds hold approximately 26 pints (12 L). Always confirm against your unit's lubrication spec.
How do I identify my Eaton 10-speed transmission?
Match the model and serial numbers stamped on the transmission tag against the nomenclature above, or use our Eaton transmission identification guide.
