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 )

not 10 out of just the 2inch, with the header possibly.

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.
