Ok so here it is im driving back from the gas station after buying a pack of marlboro's and im approaching a red light; so I start down shifting but when I down shift from 4th to 3rd and 3rd to 2nd I hear this horrific noise. I dont even know how to explain it because I've never heard anything like that before. I don't even know what to search for on the forum to see what the problem is? I only have 5k miles on my VIII and still stock, my mods are sitting in my apartment and I need to find out what this is first before I start putting them on.

 

Is it a metallic 'clunk' type of sound coming from the rear? Give some description.

 

no its coming from the front and it doesnt sound like a clunk. its really wierd i cant explain it.

 

Anybody else?

 

If you put the wrong transfer case oil in, that could cause and issue. Transmission fluid in the TC will cause it to howl in about 4-500 miles. BTW, dealerships have been know to make that mistake.

The cone filter will mess with your MAF. For basic stock car, the stock airbox will work better, believe it or not. If you take the car to the dealer, you might want to put it back on.

 

i didnt put any fluids at all. do you think the dealer would do this under warrenty?

 

It's possible it can be a problem with your LSD. When you downshift, what RPMs are you downshifting at, also. Do you nudge the throttle to match RPMs?

 

Give us SOME kind of description. There has got to be a way to compare the sound.

 

c'mon, give us at least a clue to the sound. I know it may be hard to describe, but is it a clunk, a grind, a whine, a pitched wistle, a moan, a chirp, metal on metal, a rattle.......

Give us something, so we can relate it to something we may have exprienced.

 

uhhh its like a deep moaning sound but ony happens when i downshift

 

Is this your first manual?

 

no. first awd car though

 

i just took it for a test drive again, and it only happens as im letting off the clutch. this noise is not always there when i down shift but happens occasionally.

 

yeah I get that too..it happens when slowly let out the clutch right after downshift right?
deep humming noise

 

yes. but its pretty loud and never did this before. i was in my friends evo also and his doesnt do it either
