Finally completed the differential fluid drain and fill today on the 1995 Camry Automatic with 2.2L engine. The fill plug was loosened first. This was NOT easy. I removed the upper air filter box cover/diffuser and inlet hose to the throttle body. I then could reach down to the differential fairly easy. I wiped off the area around the fill plug. I broke the over-torqued plug loose with a 3/8" flex head ratchet and a 17mm 6 point socket. I then broke the drain plug loose and removed holding a bucket up close to the drain hole. The old fluid came out almost black. I then cleaned up the drain plug and magnet , inspected the drain plug gasket and reinstalled the drain plug and torqued. I lowered the car and filled from the top side using a funnel with a hose connected and routed into the fill hole. ATF was added until it ran out of the fill hole. The fill plug was reinstalled and torqued.

 

after reinstalling the plug did it run smoothly? I suppose it is

 

Great job!

Keep an eye on the leaking fluid and make sure the diff does not run out damaging the diff gears. This has happened.
