I changed the lefthand diff seal, so followed/did the below:
Manual says 2.4 ltrs SAE 75w-80 for the transaxle.
I drained about 2.8 ltrs from the *bottom* 23mm drain plug, below the diff area.
I found a 23 plug at the top of the diff and added 2.4 ltrs of SAE 75w-90 (Mazda dealer said OK to use).
Then, I checked another 23 oil level check plug at lower/front of g/box. Nothing appeared, so used small probe camera to view inside the hole.
I cannot see any oil, but there are plenty of gears.
What am I doing wromg or missing.
