I am doing an oil change on a 2004 GD Subaru Impreza 2.5l RS (peanut lights). As usual the engine oil does not register on the dipstick and there is no coolant in the overflow bottle - both now fixed.

I doubt that at 155,000km the front diff/gearbox oil (one unit) has been changed nor the rear diff. Is a 5 speed manual box.

The car's handbook indicates that there is a dipstick with a yellow handle on the drivers side - sort of under the air cleaner and that gearbox oil is filled through the dipstick tube - problem is there is no dipstick and no dipstick tube.

Any clues and how do get the oil into the gearbox - rear diff is no issue - just drain and refill through the filler hole like any landy.

Thanks

Garry
