I swapped a fully functional C4 to AOD 2 years ago.
After the AOD was installed I noticed vibration in 3d . The vibration also occured in P/N when revved up to around 2500 rpm
We canged converter, but it only got worse. A secondary vibration was introduced when AOD shifted from 2-3d.
We swapped the AOD to a another AOD. Vibration only got worse. Now there is constant vibration i 40 mph in 3d and 60 mph in 4th.
There was no vibration when the C4 was on.
What are we doing wrong??
(Oh, yes, The flexplate is the right OZ - we have checked several times)
