Does it stop when it shifts into 2nd. If so that is normal whining, all trannies do it. Test it out if you don't believe me, put your auto shifter in 1st and slowly accelerate till around 25, and let your foot off totally, you'll hear the tranny whine. Of course do this with the radio and stuff off. After that, put your shifter in D and drive normally, you'll hear 1st gear whine, it'll shift into second, and the noise stops, then thrid comes along, and fourth. No noises in fourth....I hope!
