Anyone know of an inherent issue with the 3.9(specifically) engine, 8 lug converter, using this trans having a severe vibration at 2000rpms? Our converter builder just told me Sonnax has a new front cover that eliminates the "adapter" plate/ring, allowing the converter to bolt directly to the flexplate....to eliminate a problem with vibrations for this engine ONLY. Sure would have been nice to know that BEFORE the 4th dang converter install....
Just curious. Nothing on the Sonnax website about it that I can find.
This is in a 2002 Thunderturd, btw.
