About 5W-30 Manual Synchromesh Transmission Fluid
This AMSOIL manual synchromesh fluid is a selection for compatible synchromesh manual transmissions. 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
Synchromesh fluid and hypoid differential gear oil serve different requirements. Follow the transmission specification rather than choosing by viscosity alone. 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.
