I am going to be changing my gear oil next weekend and had a look under the car and can only find the drain hole. Anyone know where the filler hole is located? The drain hole is right on the bottom center of the transmission case and looks to be a 3/8 or 1/4 inch drive.
A bit more info that others might might interesting/helpful. Car has 65K and the dealer recomended I do it, they told me this when I was in for a free oil change. iirc they wanted 289.99 plus tax for a flush and fill. My mechanic said he would do it for 90 or less (1hr labor) if I supply the oil which is 75W85 semi syn which I think is API GL4. I figured it's not a hard job so I'll do it my self. Oil from the dealer was 24.99 per quart and it apparently takes close to three. Everywhere online just says drain for 30 minutes then fill until it starts to over flow.
Any advice would be appreciated.
