Driveline Click 08 2500hd

[Jpakutz]

I have a nasty click in my 2008 sierra 2500, it is the GM 6 speed on a gas truck, this noise only occurs when I put the truck in drive or reverse, and its when the tension hits the driveline, no problems with drivability or clunking during acceleration/deceleration. The truck has 120,000 miles on it I did change the u joints with moog HD versions and this did not solve the problem it sounds like it is coming from the area of the transfer case but its hard to tell being as that the sound travels throughout the driveline. the truck is also throwing A code for transmission pressure sensor code any input appreciated Thanks!

Lube the drive shaft spline with some marine base grease . That will stop the clunk. As for the sensor, that is something I cannot comment about.

Oh, just search for a how to to show you how to go about this if you need.
