I just got my gt a couple weeks ago and i noticed under "heavy" acceration theres a little rattle coming from the tranmission area..is this normal??

 

Congrats on your new Stang! Are you telling us that you're out banging gears and smoking tires? And experiencing the forces of rapid acceleration?

The rattle you're hearing is kind of hard to diagnose from here, but most likely its normal. I don't recall hearing anything alarming but there are some "machine" noises coming from the trans tunnel. Sometimes you can hear them over the sounds of exhaust and tires.

 

The fix...
Louder exhaust to drown out the tranny goblins

 

haha well if thats the fix then im sure my slps on their way should take care of it
