[Fireplug]

Need more info!
1. the noise does it happen while driving sitting at idle or both.
2.when does the noise stop trans in park , drive, n, rev,??
We have to find out if its in the drive line(rear end ,axels bearings stuff like that) or an internal trans noise ,engine .
If the ps was low of fluid are you SURE the pump is not making the noise?? ps pumps are known to make very load noise while the truck is moving.
Open the hood with the engine running in park with the ebrake on and rev the engine any noise???
Lets know
