I still have a serious clunk in the drive train of my GXP and I have had it to the dealer twice and they contend that they cannot duplicate the problem.
I have stated this once on here a while ago but I'll state it again because my warranty is
about to expire.
After accelerating, you let your foot off the gas pedal and start coasting. When you press the gas pedal again, either hard or soft, there is a big clunk in the drivetrain somewhere. It is less pronounced if you actually use the brake and slow down first.
It is more noticable on the highway if you are using your accelerator to monitor your speed. It doesn't do it when the car is cold.
The first visit I told the dealer the symptoms and suggested the transmission. The second visit I said it was worse and also check the motor mounts. The service manager said they couldn't get the car to clunk.
It'* really bad, I don't see how they couldn't duplicate it. Any ideas?
There is another Pontiac dealer on the highway about 15 miles from me.
