Ok to make it quick and short I have a noise which is coming from under the car. It started off as a rattling which I thought might just be the heat guards on the CAT but now when I'm accelerating at about 3500 RPMs there is a loud squeaking noise. I don't really hear the rattle anymore and this also happens when I down shift and get to about the same RPMs. Its really noticeable going from second to third and back down to second. It does happen sometimes going from first to second. Any help would be great.

Thanks!

 

could be anything really. too vauge of a post.

could be t-case if its more of a whineing sound not a squeaking.

do you launch the car alot?

 

well the sound to me could possibly sound like a squeaky belt. Its really hard to describe. I don't launch the car very often but I am an aggressive type of driver.
