If you guys are still looking for Transformers sounds, check these pages out:
Many of the other G1 characters have sounds on their pages too, use the left top sidebar to browse through that era of TFs.
And I've attached some clear TF Sounds.
Also have a ton of Prime from the 2007/2009 Movies, some dead clear. Ripped from various flash applications around the web that were used for promo, if you need/want Prime sayings.
Don't have my Camaro BB yet, dealer looking to allocate from another source, but when I do, I will be looking back here, because I MUST have the TF sound for my arm/disarm sounds, some how.
