2007 Ram 3500...58k miles . I tow 23,000 GVW three car wedge hot shot trailer 2,300 miles weekly...
Two weeks ago at 60 mph, the flex plate cracked allowing the bolts to loosen taking out the torque converter to the point all of the ears sheared off the converter. Also took out the starter gear etc. Trans was also take apart to try to locate the source of the "implosion"....Dealer found third gear clutches burned. Dodge has a 30 day B/O on the trans an out of the 3yr / 36k warranty anyway.
Had a B & D trans and billet converter built by a reputable high end diesel shop using my tranny as the donor. It was then Dodge Dealer installed on Friday ....
Now have a medium vibration in and out of gear at idle and less as I run up thru the RPM's .......any ideas ? ~Alan in PA

 

did you have your old trans redone or just buy a bd trans? maybe on yours one of the shafts is slightys bent that the dealer didn't find? if it's happening on the new trans, i would check all u-joint's.

 

Turned out to be two bad injectors that happen to show up the day I got the trans installed ...tnx !
