I have a 37' 2004 Newmar Kountry Star on a Freightliner chasis with a Cummins ISB 300 engine and an Allison MD3000 transmission which is all very nice when it runs but I have had 3 flexplate failures . The first in Aug/07 at 10,000 miles,the second in July/08 at 16,000 miles and the third in July/09 at 22,000 miles. Can I expect another failure in July of 2010 ??? None of the abovementioned manufacturers can explain the reason for the failures and I think they are just waiting out my warranty untill it expires in Sept/09. Has anyone else had problems with the same engine tranny combination like mine? - what caused the problem and how did they fix it. I need help!!!!!!
