98 Intrigue tranmission ?'s

[2wheelcowboy]

Helleo to all. I just joined the forum tonight. Hopping to get some help with my wifes car. I have read several of the threads regarding the problem with the transmissions on these cars. On several of the threads many of the members were reporting of a whining noise when car was in Park or Nuetral. And I saw the tech report from GM on this.
My wifes car is just the opposite. I whines when put into gear and of course changes pitch as you increase speed.
a) car shifts perfect(no hard shifts)
b) accelerates fine
c) no shuddering
d) just replaced waterpump and thermo 3 months ago
e) flushed trans last winter and will do same next weekend
f) car idles smooth as ice in park,nuetral or stopped at a light
and is very quiet at the same instances.
As I stated above, I plan on flushing system out next weekend nad will be using the products that have been suggested by the members.
Any additional information will be greatly appreciated and used to the best of my abilities.
A thatnks for putting up with another newbie.
