When you post, it's a good idea to include as much information as possible. How many miles? Why do you think it's the transmission?

With the limited information, I would guess that the tensioners have worn out and what you are hearing the the timing chain rattling.

my car is a 1998 sentra and the motor has 45,000 miles .i also thought that the thing that makes the noise is that i have exhoust headers, CAI, and no resegnator and also a preformance muffler. thats about it, ( it only makes the noise when im close to 5 rpm's) if its not those parts that make the noise, is what you said bad or ok?

if it makes a hard metalic sound i doubt its the tranny. did you have a full exhaust put on? header, new piping, muffler? i would bet my life savings that it is a the exhaust hitting something. or a heat sheild.

i dont have a catback system and no heat shield.
so you didnt have a new exhaust put on? just a muffler? .........where is the sound coming from? it could just be a crappy muffler. i have heard many a buzzy/tinny muffler on a stock sized exhaust pipe.

get your car on a lift and trace the exhaust pipe from the header all the way back to the muffler and look for contact on anything.

side note; what type of header and muffler do you have? a high flow header and "performance" muffler on stock pipe will not do you any good other than make your car sound like a pissed off penny racer on crack. i would get 2 inch pipe with the longest res you could find put on and see if that dosent solve anything.

FYI, the tranny would make more of a "clunk" than a hard metalic "clank/ting" because it is muffled by the tranny fluid. <im not sure if that is 100% true, but thats what i would think )

i do have headers (cant remember name). when i drive the noise comes from the drivers side where the tranny is at. so i thought the noise was from there.last night as i was driving home i was in second gear and my car stated to jump and pull but the rpms where rather low could that be the reason my car jumped and pulled and could that have to do with my noise question.

do you have a standard? if you shift and its to low you wont have enough power and it will want to stall. but i still dont think the noise is from the tranny, i had clunking noises and it was the axels.

sidenote: its "header" there is only one ;) if you had a V-6 or V-8 you would have 2.
