Hubert Glass Oil Synthetic Trans 40W Oil 5-Gallon Pail #G40S-5
The Hubert Glass Oil #G40S-5 is Glass Synthetic Trans 40W in a 5-gallon pail — the heavy-duty 40W manual transmission grade from the Glass book: per its data sheet, the Synthetic Transmission Fluid HD line for Eaton, Meritor and Mack heavy-duty manual transmissions (API MT-1), built for extended-drain on-highway service. The drum version (G40S-D) is stocked alongside it.
This is an application-specific grade — it goes where the equipment manual calls for a 40W transmission oil, not as a substitute for other grades. We confirm the application before the order ships.
