Did I F Up?

I was changing the fluid in my 04' ZHP manual transmission and was torquing the bolts down to 44 ft/lbs as I read in another thread. The drain bolt was fine and torqued normally but the fill bolt went loose before the torque wrench clicked. I pulled the bolt back out to inspect the threads and they seem to be ok. The bolt is a 8MM Hex bolt which I think is aluminum (Can somebody confirm?).

Anyway I put the bolt back in and screwed it in as best as possible and it doesn't seem the be leaking overnight.

What are your thoughts?

Did you check the threads in the tranny? The tranny is aluminum but the plug is steel.

this is my drain plug.

is that one aluminum or steel? It's hard to check the fill hole threads as it's a tight space.
