Can I use this in my 2001 silverado 2500hd with an allison transmission?

Yes, I recommend flushing and filter (Both) try to remove as much of the Dino oil as possible. Transcend works wonderfully in my '01 and '05 Chev Allisons

I am trying to find the color of the fluid. Not able to find it on the product description. Any comments?

It's red. Just like the older version.
