Have searched through the driveline threads and haven't found a similar description of my problem....
In my 06 GXL 4l auto, I am getting a considerable low rpm shudder at around 1000-1100rpm, quite noticeable going up a slight incline at around 60km/h, and still noticeable on flat streets driving at 60km/h, so it's getting quite annoying driving around the city !
It feels similar to when you are driving a manual car in too high a gear uphill and the driveline starts to vibrate.
My 05, also a 4l auto didn't do this.
There are a lot of potential causes here, wheel balance, harmonic balancer, broken engine/gearbox mounts, uni joint, dirty injectors etc etc.
Has anyone experienced a similar low rpm shudder/vibration to this and found an obvious cause ???
Thanks for your input !
