Hey again, one more question thats buggin me:

Accelerating a little harder than maybe i should :-D , i notice a loud shrill at a little over 3,100-3,200 rpm, ive determined it wasnt the engine making this noise by parking, poppin the hood and revving it past this point several times...no noise, so im starting to think its possibly the transmission...but i dont know... :-? btw..this noise kinda sounds like its at the top of a gear and then it shuts up after it shifts gears, just a thought..also it doesnt do it all the time, but its enough to get me worried

Thanks Guys
