Help before I dive in...

Hey guys, I have a 2002 4.6is with 90k miles on it. Engine runs great but I do have the hard 2-1 downshift unless I drive it in sport. I noticed the other day it was whining (supercharger sound) at low speed acceleration. It doesn’t whine in neutral or park, so unfortunately its looking like I might have to do a TC replace/rebuild. However....I have noticed on a few occasions my battery light came on for a sec and then went away. Is it possible at all that my alternator could be going and the whining is coming from that? Hopefully it’s not just wishful thinking! I also need to change my fan belts, so I’m just wondering if I definitely have to change my TC? I have BC coilovers, axles, and rear subframe bushings going in next week (hoping it dissolves the 2-1 downshift issue), and if I have to do the TC I’ll do it while the car is up. Also, I have no trans shifting issues or codes that come up. Thoughts?
