It was a bit of an adventure, as the fill bolt took some effort (pounding with a hammer, lots of penetrating fluid, and multiple attempts with muscle and an impact gun). I also had to purchase a 24mm socket. But, it finally came off.
I drained 350 ML. So, it was obviously low. I added some 80w-90. I had one pump hose blow off and spew oil all over. LOL. Luckily, I was on my side driveway, which already has oil spots and isn't front and center. The drain bolt has a number of a small metal shavings on it.
I took it for a drive, and there is definitely a substantial leak. In a short time at the gas station, there were already drips. I have a clean tray under it now, and I'll try to pin it down more.
This is the first time I've ever changed differential fluid. So, it was fun to do something new.
More car specs: automatic (3 speed), 2TC engine. Aside from this issue, it starts on first or second crank, and shifts ok. The speedometer seems like it may be off. I do see RTV sealant around the bell-housing. So, I wonder if at some point someone changed internal components (as taking it apart isn't necessary for drain/fill), and may have done so improperly.
How you like that GL-5 smell?
I hated it for years but now it piques my interest.
