Newby here, By the way, GREAT SITE! Anyway, I am the proud owner of an 06 shee that supposidly has only 20 hrs. on it and it actually looks almost brand new. My question: is it normal for the tranny to make a high pitched whining noise kinda like a super charger noise on a performance v-8? I also changed the tranny oil and there are tiny aluminum like particles in the oil. Please tell me this is normal. Any advise or info. is greatly appreciated!
