2004 Chevrolet Silverado 1500 4dr Extended Cab LS 4WD SB (4.8L 8cyl 4A)
After 6000 miles the drivetrain started
clunking loudly any time I drive
backwards (in reverse). The clunk does
not occur when I shift to reverse but
clunks when I accelarate faster than
normal. The clunk also occurs
frequently when I accelarate hard and
then let off the throttle. It sometimes
occurs on 1st to 2nd upshifts or
downshifts. I can feel the clunk in
the floor and passengers ask me about
it. This problem takes all of the joy
out of owning this new truck.
The dealer did the transmission
reprogramming which did not correct the
problem and they told me that I have to
live with the problem. Many other
owners are having the same problem.
Fix drivetrain "Clunking", interior
rattles from dash, door panels, and
headliner. Calibrate the Auto
Headlight feature to turn on when
it starts getting dark. Fix Key Fob
design so the Panic Alarm stops going
off all of the time. Upgrade poor
sounding stereo and speakers.
