hey guys need some help, my tranny has been replace about 5 month ago, new one. it was replace because it was making some wierd noise when u go about 40 or 50 mph when you gas it a little. it's like a whistleling noise. it only made the noise in 4 and 5 gear. so acura gave me a new one. but i knew something was still wrong because it still made the noise on and off, but EVERYTIME i would bring it to the dealer the noise would go away. but UNTIL now the whistleling noise is there allll the time. and it makes a funny idle sound like dropping the rpm to 800 to 300 and up to 1300 it keep rising and dropping. Whats is wrong??? sounds like it's running on 3 piston put i dont see any smoke coming out. and the engine vibrate around 1400 rpm. is it the engine or the tranny or both? thanks guys... appointment with acura this week. need help because my acura people don't know much. trust me..
