Trans shutter

[brschriever]

Not to long ago my 03 commonrail with a 47re trans in it started to want to shutter around, trans has a billet flex plate and input shaft, Dayton HD single convertor, and trans go shift kit, I don't know of what else, but when my truck locks into OD and I try to keep it steady at around 50 the truck will start to have alittle buck to it until you speed up till 60 and it's gone. Anyone have a idea of why it shutters?

Shudder or buck? Converter shudder is usually fast and light. Engine misfire can buck or stumble hard and u can almost feel the engine firing
