i am posting this for my buddy cuz this happened today around 6 and there are no shops open until monday. he has an 02 tahoe with 71,000 miles on it. he got home parked, then later got in and started it up, said he heard a weird sound then went to put it into reverse and it wouldn't do anything. so i went over to check it out for him. i have worked on a lot of cars in my time and have never in my life heard a sound like this. basically when you start it up it makes a whining sound while in park, neutral, and reverse, and when you put it into drive the noise go's away. while in park once the rpms are above 1500 it go's away. well i warmed the motor up and checked the tranny fluid and he was low, and added about a 1/2 a qt. to bring it up to level. the noise was still there. we later decided to push the truck back and see what it would do in drive, and when he started off it made the same whining sound. also there are no visible leaks of any kind. it almost sound like there is a problem with the fluid pump but was wondering if anyone had ever experienced this problem. any ideas?
