One on the bottom of the gearbox and two, one fill and one drain, on the rear face of the rear diff. Always remove the fill plug before the drain plug.On this model WRX, where are the various drain plugs located and do I need the t70 torx bit to remove any said plugs?
The manual specifies a specific weight of GL5. Since you are under warranty I'd follow the manual.What kind of gear oil would be suitable for this type of tranny?
No. Use only specified fluids of correct viscosity and API grade.I've got 52,000 miles on the tranny, should I consider any kind of conditioners for the oil due to that mileage?
