Hi everyone, yesterday I did a manual transmission fluid flush on my ZLE. To fit a ratchet onto the fill plug, you have to unclip the the transmission cooler line to get enough clearance, or unbolt the retaining bracket from the transmission. I did the latter.

Unfortunately I forgot to put the bolt back and I lost it! The transmission cooler line isn't fully secured now so I don't want to drive the car much until I can get it clamped back down.

Anyone know the part number for this or could tell me what size bolt it is so I can just get a replacement from my local hardware store? I was unable to locate the assembly by browsing on gmpartsdirect.com. It is pretty small, hex head, and didn't require much effort to loosen since it doesn't hold much.
