Other Drivetrain Fluids:

There is no recommended replacement interval for the transmission fluid on late model Subaru vehicles. The same applies to manual transmission and front and rear differential lubricants. In all cases, the recommended procedure is a fluid inspection at 30 month or 30,000 mile intervals. If the fluid in any of these units is found to be dirty, contaminated or at the incorrect level during the inspection, fluid replacement and/or seal or gasket repair are the only options.

Maintenance: Subaru Periodic Vehicle Maintenance Services: Making use your other drivetrain fluids are in good shape is a good way to ensure that your Subaru AWD system is in good working order.

Differential and transmission fluid recommendations for varying climate conditions can be found in the appropriate Subaru service manual. Subaru recommends against the practice of mixing lubricants from different manufacturers. Although both may comply with the GL and API ratings, lubricants from different manufacturers are refined from different base oils and additives. Combining them may produce unpredictable results.

Rear differentials and manual transmissions feature familiar add and drain plugs, while many Subaru automatic transmissions actually have a drain plug in the transmission pan (a feature welcomed by anyone who’s ever had the misfortune to take an ATF bath). Another welcome feature is the fill level dipstick that can be found on manual as well as automatic Subaru transaxles.
