After another 30 years they might address that.





I dont own new shit nor will I but I guess I'm not sold about having 37 gears when all I'm reading is its constantly hunting for shit.

My work truck is a 2024 F350 with a ten speed. It shifts fine, haven’t had any problems with it hunting gears. Only has 19,000 miles, though.

Knock on wood, but we’ve had 25-30 6.7 fords and no CP4 problems. Not a huge sample size but not totally insignificant. I’m currently on my third. I put 230k on the first one then the next guy drove it to 340. I put 330k on the second one and it’s currently a spare truck that works fine. I’d probably be singing a different tune if I’d had one that grenaded.

you're pretty lucky then. ive known two guys who have had theirs blow up. i told a coworker about it and i think he put a bypass line or something in his so when it blows its just a pump and not the injectors too.

only other Ford truck we have (have a few exploders and they seem to run fine and are reliable) we have in our small fleet of about 30 vehicles is an f150 king ranch that i have to keep paying out the ass to put cam phasers and turbos in. i fuckin hate that truck and i dont even drive it.

The problem with bmws is the owners. Specifically the ones that bought a used bmw and are too fucking poor to maintain it properly.

The amount of shit that needs to be regularly serviced and the labor that fixing shit routinely entails really cranks the "Altima factor" to 11 on those sorts of cars.

As the owner of a GM 8 speed and a Ford 10 speed (in an expedition) I’m not overly impressed with either.

I hear that all the time with GM and ford but rarely on the dodge/ram ZF.

I can't say they've been any worse than anything else I've ever owned, I've had a few different BMW models over the last 15 years and with the exception of rear ABS tone rings on one and a cabin blower on another, everything else has just been oil and brakes. I guess I've been lucky with mine 🤷‍♂️

Someone believes everything he's read on the Internet about the cp4...

As the owner of a 6.7 powerstroke, I am of the belief that the exploding cp4 thing is all about maintenance. My 2016 has 215k miles, I fuel at Love's (high volume of diesel going through the lines) add some hotshots every day diesel treatment with every fill up, and drive it. If the cp4 concerns you, there is the dcr pump from S&S diesel, or the RSX pump. Either one of those options will run you about $3,000 installed to eliminate that worry, if the cp4 is really a huge concern.

It's only $2k in parts to swap out the CP4 with a better one before it fails. Buy truck, spend the 2K on the replacement and drive on. Easy peasy
Click to expand...
I've got 215k on my cp4, and I just drive it. That being said, even if you pay someone to install the dcr, you'd be out around 3k. Given the costs of diesel maintenance, $3,000 isn't that much. I've actually been thinking about spending the money on a DCR pump lately, but haven't done it yet.

Why did GM have a class action lawsuit on the CP4 and stop using it in 2016? Why did ram walk away from the CP4 after 2 short years to go back to the CP3 and offer to put a CP3 in any CP4 ram for free under warranty?

While I wasn’t the one arguing the CP4 and I have tried my best to stay on the topic of the discussion of transmissions I have had multiple friends (not the internet) get shafted by the CP4.

I've sent 2 company trucks (Duramaxs) to essentially scrap because they had a CP4 die and eat the fuel system. Both were under 200k miles, one was less than 150k as I recall.

The real question is how has Ford avoided doing a recall?

Some mumbo jumbo about superior filter setup and it "not being necessary" IIRC.

Makes sense if you realize that Ford is the closest thing the US has to a useless European car company run according to European engineering principals.

I've had to do the carrier bearing and front driveshaft.
It needs wheel bearings.
But the drivetrain has been excellent.
I figure 180k miles on wheel bearings was a pretty good run.
Like I said, nothing abnormal.
Except the eccentric shaft sensor. I did have to do one of those at about 150k. Was pricey. Not a hard job though. I think it was 3 bills for the sensor. Only time it failed to start ever. Not really any different that a cam or crank sensor issue.

you're doing what 99.9% of the people who own those trucks wont do, and thats put in the additive at every fill up. that gives the lubricity that the ULS diesel didnt have compared to the old days.


i dont need the internet to tell me what people i know tell me. first i ever heard about it wasnt on the internet, it was another engineer i used to work saying he just got his truck back after paying $12k to do the whole deal after his pump blew up. He told me it was so common, you just call Ford, they know all the parts you need and they sell it to you as a package, and at the time (maybe 6-7 years ago?) it was $5k just for the parts. i was amazed as id never heard of it before, but admittedly at the time i didnt pay attention to what Ford was doing to its trucks and customers. but apparently, its a real thing.

they're getting sued right now. its a simple cost analysis. just like they explained in Fight Club.

I’d have to understand the laws behind what requires a recall. If it’s nothing or there’s loopholes that could be it.

There’s a class action lawsuit with ford over the cp4 going on right now.

So Ram got sued and issued the recall? Is Cummins just better to its customrers?
Is the failure rate to the vehicle population not high enough?

Ram dealer that my 19 got towed to had the entire parts kit in stock and had the truck back to me in 6 days covered under warranty. Happened somewhere around 25k. But was before the recall was even unofficial, so just went from v1 to v2 of the Ram/Cummins CP4.

This seems plausible. Every 6.0/6.4 owner I know of has had a bad experience. Especially with the 6.4. I've only heard of the cp4 failures through the internet.

they got sued in 2021. chevy got sued in 2019. this also mentions the american diesel fuel.

as far as i know, Ram was the only company who has used the CP4 and then quit as the problems rolled in. i think Ford and GM are still using it on everything.

2021 Ram CP4 Lawsuit​

A Ram diesel truck class-action lawsuit filed in October 2021 alleges Fiat Chrysler Automobiles (FCA) of knowingly selling Ram vehicles with defective fuel pumps that can cause engine failure. Affected vehicles include the following:

  • 2018 – 2020 RAM 2500
  • 2018 – 2020 RAM 3500
  • 2018 – 2020 RAM 4500
  • 2018 – 2020 RAM 5500
Heavy-duty Ram trucks equipped with the Cummins 6.7 diesel engines are at the center of numerous issues affecting these heavy-duty trucks.

Filed by three plaintiffs who own a 2018 Ram 2500, 2019 Ram 3500, and a 2019 Ram 2500, the complaint also sued Cummins, the company that manufactures the 6.7L Turbo diesel engine. These same CP4 fuel injection pumps were the subject of a 2019 class action lawsuit involving GM’s heavy-duty Duramax trucks.

Allegedly, the CP4 high-pressure fuel pumps have imperfections that can cause metal pieces to grind against each other, producing metal shavings that can destroy the engine.

This has resulted in stalling and even total engine failure, which poses a serious safety risk. For many owners, issues with their Ram vehicles happened as early as the first mile or after the fuel tank was filled with diesel fuel for the first time.

The 2021 class action suit alleges that CP4 fuel pumps cannot be used with U.S. diesel fuel and that both Ram and Fiat Chrysler have been aware of the problem for over ten years.

It is unacceptable that a vehicle advertised as a “diesel fuel truck” cannot handle diesel fuel. To make matters worse, it does not look like there will be an adequate solution to these concerns any time soon.

According to the National Highway Traffic and Safety Administration, Fiat Chrysler told dealers that a remedy for these problems is “not currently available.” A recent Safety Recall Notice by the automaker does not specify when Ram truck owners will have their vehicles fixed

GM switched to a Denso pump iirc.

My service truck that was bought brand new had a CP4 blow up. Oil and ALL FILTERS were changed in that truck like clockwork every 5k miles. I thought I was in the clear with the CP4 issues but at 196k miles it randomly blew up driving down the highway and cost my company close to $23k to fix.

So with the excellent maintenance and fuel from reputable stations why did it blow up? 🤔

I also used Howe's fuel treatment consistently.
 
I keep looking for the gear ratios of the Powerline AT8. I see 4.89-0.64 spread. Can anyone find what is in between? I would be curious if its a double or triple OD.
