06 ISX cummins question

the three pedal autos are better than the 2 pedal. we had one in a freightliner century and it was a nightmare. replaced a ton of wiring harnesses, x/y shifters, and trans control computers. they start to wear and go haywire. my advice is steer clear of them unless you cant shift. just my .02

I dont know much about automatics but have had quite a few isx's. My biggest problem with them has been turbo issues after 500k. I have 2 with twin turbos and had to have them replaced more times then I can count. I finally went over to a garret settup instead of oem and have had good luck with those. The stock ones seem to eat up impellors and have waste gate issues. If it hasn't been in the shop i would find a reputable mechanic to look it over with a fine tooth comb. Its better to give a guy a hundred bucks and be safe then to spend thousands on somebody elses problems. Also check the fuel filters, cummins tend to be very picky.

Anybody know how the newer ISX like 2012 and up are doing ?

That delete is about 15000.00 ? I have a 2014 579 with only 78000 so far the only bug it has is regening and it goes to cummins next tuesday to get a new turbo and a catalast they are hoping that will take care of that issue ..I really like the truck it has the ISX 525 hp 13 speed so far it gets 6.1 mpg pulling a tanker and hopper

I have 2005 Intl 9400i with an ISX which I bought new. It now has 1,340,000 miles on it and the neither the head or pan have ever been off this engine. It uses nearly no oil yet. Oil analysis every oil change (12,000 miles). That is plenty early for some people. Too long of service intervals has caused some of the issues with the ISX (cams etc.). My EGR has been unhooked for 4-5 years. EGR issues were the biggest maintenance cost on this truck.

This ISX and my Cummins shop have treated me well over the years. Some say I'm lucky, maybe, but I've taken good care of this truck and plan the rebuild it and run it another million. It's the right truck for the job.

Be careful of fleet maintained trucks. They are looking for "low cost of ownership". Probably smart business on their part. But the second owner could be hit with the repair bill for the minimal maintenance of the first. Might be OK if you buy it right.

As far as the auto shift, I have an o/o with a new Volvo with the "I shift" Running through towns with stop lights I can't shift fast enough and I have 100 more hp than he does. If I were buying new I would have an auto shift. I have heard some of the older ones had some issues and are expensive to work on.

Has anyone heard that the EPA is going to crack down on glider kits and make them meet the new emission standards?

Have 07 ISX in shop now for inframe overhaul. 770000 miles. Cracked head was pushing air into cooling system. Getting reman head and usual stuff. No new injectors or dampner. No turbo, Estimate sitting at $16,250 P & L with no extra warranty. Could be more if they find anything else bad and if anything needs machining. Feel free to contact me if you want the end result in a week or two. [email protected]

Best thing to do with an ISX Cummins is drop it in the ocean and forget where you dropped it

I got talked into an ISX in a 2005 KW. it was a disaster. After 3 years I gave up and replaced it with a 3406 E CAT. Best thing I could have done. I am partial to Cat power. The ruck now does well and EVERYTHING works factory. Ray at Arizona Diesel Solutions built a wiring harness so that everything just plugs in and functions correctly. Let us know if we can help.
