At the end of the test they were going 2600 RPM at 25 mph. Truck wouldn't downshift. I wonder what would have been different if they put it in manual. To be honest I never put mine in manual, but I have not towed the IKE.
I wonder if it fails to downshift because at that altitude the engine doesn’t generate enough torque for the transmission to sense a downshift pointShinerBock wrote:
The current CP4.2 is not the same as the old one that was notorious for failing on the 2011-2015 Ford and GM trucks. There is a different cam profile among other things and the max pressure was raised from 29k to 36k.
I believe the new Cummins is only pushing out 29k psi which plays a huge role in the pumps longevity and reliability since it is not utilizing the pump to its max capacity like Ford and GM were with the old CP4.2. The new 2020 PSD is utilizing 36k psi from the new CP4.2.
Interesting info. It will be interesting to see how these pumps do in both the new Ram and Ford. I won’t be personally experimenting though because I’m holding on to my trusty CP3 powered truck! :)- The current CP4.2 is not the same as the old one that was notorious for failing on the 2011-2015 Ford and GM trucks.

My biggest concern going diesel is with all the Emmisions **** on them, and the cost to repair it. I know some have no probs, but you read stories all the time of CP4 fuel pump grenading and costing $10k to repair, or $5k Emmisions repairs.
I keep trucks well past warranty, my current truck I've had for 17 years, and 235k miles, and I've had 2 engine repairs. A fuel pump at 195k miles, and at 210k I had new rear main seal, oil cooler lines, valve cover gaskets etc replace because it was dripping oil all over the driveway. Total engine repairs over 17 years is less than $2500.
I'm debating new trucks now, and diesel vs gas is part of the debate. There is no denying that the diesel is a beast towing, but I'm only towing 8000k lbs, and I'm in the southeast, so we've got little hills compared the out west. After 15-20 years resale is not real a huge concern.
I believe the CP4 problem and warranty denial was a Ford problem. GM and RAM seem to have far fewer problems. If you are stuck in the Ford camp then I guess you get what you deserve.
The new Ram Cummins welcomes you to the CP4.2 and all it's glory for years to come.
I wonder if they will deny warranty claims - oh wait that was Ford.
I wouldn't hold my breathe based on FCA's history on handling safety recalls. And that Ram Cummins with the CP4.2 has limited warranty so FCA will stick it to you either way.FishOnOne wrote:

I wonder if they will deny warranty claims - oh wait that was Ford.- I think it’s pretty impressive it took having the throttle pinned for over 10 minutes at that load in stride.
- The funny thing is, the dB on that truck screaming at 5K towing a trailer is lower the the 2k cruising dB on my truck with no trailer.
That was impressive. wing_zealot wrote:

That's BS, when you're towing 10% of time and commuting 90% of the time, "those other factors" are very pertinent. You need an adequate tow vehicle but you also need a very good commuter vehicle.
The advice and info you will gain on this site applies strictly to towing. Those other factors are not pertinent when it comes to the tow vehicle discussion.
I can tell you my dually can be used for commuting but its not the best commuter vehicle. However it works great for towing my 5'er.
My dually may not fit in the average garage either.
Again this is the tow vehicle forum not the multi purpose, best bang for the buck forum.
Once we stray away from towing, the discussion gets generalized and is no longer contains beneficial towing info.
I know my dually does not make a great commuter vehicle, do I really need to seek out info on how hard it is to park it in an urban area or tight parking lot? That's simply not what this forum is about.
However if someone wants info on how a dually tows vs. a SRW. Or how heavy can I tow with a F150 you are in the right place.
Of course one may have other criteria to consider when buying a vehicle but those criteria are generally not universal to all.
You end up with a meaningless apples vs. oranges discussion.Flashman wrote:

IIRC the OEMs used to derate the GCWR of vehicles with normally aspirated engines 2% per 1000 feet of elevation, which of course translates to a reduction of 22% for the top of the Ike. Reading the towing guides for both GM and Ford I can't find any reference to this.
