rattling noise when accelerating
 
well for awhile now, iv noticed that when im accelerating from a stop, theres a rattling sound. this can also happen when im accelerating while driving, but i dont notice it as much.
my car has been leaking transmission fluid from the axle seal for awhile now, but i dont have the money to fix it, so iv just been putting more fluid in. could this be a cause?

Could be, but that leak isn't helping.

or maybe it could also be your exhaust pipe falling apart...or maybe its just touching the shield...

but then why would it only rattle when accelerating?

Because when you accelerate, the engine mounts flex, allowing the engine to lean backwards, which causes the exhaust system to flex into a new position.

thanks.
i sure hope its the exhaust and not the transmission

I hope so too, but noises are the hardest thing to diagnose over text messages... :D

The fact that it changes with throttle suggests that its not valve/lifter noise.
If it were wheel bearings, it SHOULD(?) change with steering around a corner.

Maybe CV joints?
Can you make the noise in an empty parking lot? Have a friend stand outside & maybe tell the location of the sound?

I've heard that Honda B-pipes have an internal pipe as well that can come loose and rattle.

yeah i had my friend stand outside the car.
you cant hear it when standing over the engine, only when you'reto the side

Crawl under the car (PROPERLY SUPPORTED PLEASE) and check the exhaust pipe end-to-end and make sure the heat shields aren't rattling against the exhaust or floor pan.
