Looking for same advise. Planing to buy new truck but do not know which one will be more reliable and with better MPG? 2016 Volvo VNL670 with Cummins smart advantage and Eaton-Fuller, AutoShift with 2.64 ratio VS 2016 - 2017 Volvo VNL670 D13 I-Shift with 2.64 ratio. Thank you
I second that, if you're going to go with a Automated Manual Transmission, the I-Shift is the best out there. The D13 is much more reliable then the ISX15.
Agreed. D13 w/ iShift all the way... Cummins has too many problems.... and average life until in frame rebuild is dramatically earlier than the Volvo D13
