Ok to jack up ONLY the rear to change out trans fluid

[JoeFromPA]

Hi all,

Been reading guides on doing the trans fluid on this car. Seems like I have to remove the diagonal aluminum support braces, which should only be done with the wheels off the ground (i.e. suspension unloaded) to prevent changes in alignment geometry.

Now, I'm not too worried about getting the right amount of fluid in the trans (i.e. trans level or not) as I have that taken care of seperately, but I wanted to know this:

Is there any reason that I SHOULD NOT remove the aluminum diagonal support braces when the front wheels are loaded/on the ground? I.e. do they somehow still bear a load from the front (I can't see how)?

As a side note, I'm going to be swapping in Mobil One Delvac 75w90, which is $52 for a gallon from Grainger supply. I'll post thoughts afterwards.
