Opinion on volvo vs detroit

Doesn't that ishift die at about 750-800k miles and costs about 30,000 for a new one?

 

I own mine 4 years, took from 700k to over a million now.I stay regional and SE in the spring.

Twice at dealership.

First time scheduled visit, replaced whole cooling package, CAC,hoses etc,
no complaints beside wrong coolant filter (or rather dummy one since I changed to extended fluid) which was replaced promptly.

Second time turbo blow up, towed to dealer, everything dandy till they send me estimate of repair.
They wanted 2x or 3x (can't find it now) for turbo itself.Since truck was apart, I went to different dealer, bought myself and bring to them.Saw light in eyes look, heard "You will have problem with warranty" bla bla BS.Got truck back, 2 years now, no problems.M and K in Kalamazoo MI.


Parts usually I order thru local Mack dealer, they have Volvo too just not my location.I live 14 miles from them.Or stop by on the way to WI.Many of my loads originate there.

 

Volvo used to have detroit 12.7 before freightliner (diamler jerks) bought detroit engines.

 

Preemission one.

 

What problems did you have on your cummins isx??

 

Sounds like nightmare. I know before 2014 isx had problems with fuel pump ceramic plungers , which ruined engine. Im curious what causes carbon built up in liners?
