Hi from Australia.
I Have a 2010 JG Holden cruze CDX.
Holden Australia have recently replaced the auto transmission free of charge ( I think they have had a multitude of problems)
I now notice that between 60 and 80 Klm/hr there is a shudder which I can feel through the floor ( not the steering wheel)
I believe that this speed window is between 5th and 6th gear.
Anyone have the same experience? Or has anyone an idea what may be causing this? Drive shafts? CV Joints?
Looking forward to your ideas.
Cheers from Rossco54

Is it a single shudder or continuous? If single it may be the new torque converter locking up.

Hi, its a continuous shudder but goes away at about 80k/h. Or if I am planting the foot to get up to highway speed it doesn't happen. it only seems to happen when I am slowly accelerating..
