automatic transmission and locking differential. It also has the towing
package and ABS brakes.

I took the truck back to the dealership service dept, they kept it
overnight but said it was normal for these trucks to make that
noise. I thought 'WTF'? I've been around cars and trucks for a
long time and never had this experience.

I'm not 100% sure its the tranny-- it could be the locking differential
or the ABS brakes, but the only way I could tell for sure is if I could
plug in some kind of scan tool or laptop software to show what gear
I'm in (since the tranny is a 4-speed electronic, it should be possible)
then I could see if, when at a stop, my tranny was still in 2nd gear.

Anyway, I just wanted to post to see if any of you guys have heard
of this problem.

thanks!
