Ok Everytime I'm goin under about 30mph and I let off the gas I hear a clanking sound somewhere under the car (in the tranny area., I think). The wierd thing is if I let off the gas and shift in to neutral I dont hear the clanking? please help what is my problem? Also i have 350whp and a stock clutch (if that matter's)

 

I know someone can help!

 

we have very loud transmissions. This noise is normal. Mine sounds like a low "grrrrr" when I let off the gas. Nothing to worry about unless it gets much louder or you notice things like shifting problems.

 

I have this problem with my hks exhaust and rnr carbon ti. It rattles against the driveshaft at deceleration and doesnt rattle in neutral.

 

It sounds like metal hitting metal, It's not my exhaust. It must be my tranny, hope it's not serious
