Lifting angle and levels when changing fluids

[2019 CX5 GT]

I'm about to change transmission, diffs and transfer case with OEM fluids and will be using stacked plywood to raise wheels.

If I do the front first without lifting the back wheels will the tilt factor cause inaccurate fill levels versus using a straight lift?

As far as the trans goes, best to refill with the same amount you took out, measure the fluid when it's cold. Then back off your plywood on a level surface and check the fluid at the appropriate temperature, 122 degrees F. It won't matter too much with the others. There's lots of room underneath to do the diff without raising it.

I would want it perfectly level. you can build cheap ramps using 2X4's stacked up one on top of each other staggered. I use 2 sets of ramps so I have quite a bit of clearance. the ramps have paid for themselves many times over.
