About 75W-90 Manual Transmission & Transaxle Gear Lube
This AMSOIL manual transmission gear oil is a selection for compatible manual transmissions and transaxles. Identify your transmission before comparing products; a vehicle’s year and engine do not always identify the fitted transmission on their own.
Before you choose
Match the required manual-transmission gear-oil specification. Differential gear lubes are not automatically interchangeable with synchronized-transmission fluids. Check fill capacity and the manufacturer’s temperature or level-check procedure when planning the service.
How do I confirm the right transmission fluid?
Find the transmission code and fluid specification in manufacturer documentation, then match them against AMSOIL’s current application list. Ask Jeff for help gathering the right product information.
