I want to change my rear diff fluid, but I don't feel like removing the cover. I have seen a lot of different fluid transfer pumps that can be used to both empty and fill the differential through the fill hole. You can spend $10, $250 and anything in between. Rather than one of those small 4 or 5 oz. pumps I'd like to get something that will empty out the case quickly. Please let me know if there is a pump you would recommend. If there is a pump that can also be used to empty out the automatic transmission through the fill pipe, I'd put it on the top of my list. I'd like to keep the price under $100.
Legal Bill
You can get a cheap fluid transfer pump at harbor freight or another parts store and do that. I did this with a lawnmower gas tank. If yours is really low mileage its likely ok to do. if its 100k or more and never been done you would be wise to do the cover and inspection. Its a $1500+ bill for a shop to completely rebuild the rear depending on the cause.
This is the one I got. Worked ok for what I have used it for thus far. I think it would be nice to have an electric or air one like posted above though.
