Does your truck have overdrive? If it does, does it have a button on the dash to turn off the OD?
If it does have OD and it had the button on the dash you have an E4OD. If it has OD but no button on the dash you have an AOD.
If it is just a 3 speed automoatic it is a C6.
What can I say Rick? I have no life

Pretty soon it will be race season and I wont have as much time to spend here.
And this beats watching the war on tv
Welcome Drow!
If it's a C6 I very highly doubt it is going bad, you prolly just need to change the fluid and filter. I had one the had almost 180k miles on it and whined in every gear, but it worked fine never gave me an problems.
sorry it probably would have been easier if i told you that it is a "T" on the <a href="http://www.motorhaven.com/">decal</a>.waiting for reply.....thank you
