Just thinking about all the Ford motor saga and in my mind put together my idea of the dream truck, Caterpiller Diesel with an Allison tranny. I believe that combo would trump all.

heard rumors of that combo years ago from GM, before they went with current set-up. word i heard was Cat required too long of a warranty that GM refused to offer, so no deal...

Why? It would probably weigh another 1,000# and cost $20k more. Ford put their diesel engine saga to bed about two years ago by parting ways with Navistar and making their own diesel. The new engine is the most powerful one out and has no issues.

I was speaking to a Ford Diesel Tec and he told me the new 6.4 has many issues that make it look like the first few years of the 6.0. Im my oppinion I would go back to the 7.3 platform. And correct me if I am wrong but dosent Navistar make the 6.4??

Ford Actually owns Cummins. I wouldn't doubt that it will be done one day. Till then I will continue to drive my Dodge. BTW the new Cummins trucks have an Allison Trans, they just didn't pay for the badging.

I have a friend that took a Cat our of a school bus with a allison trans, and shoe horned it in a 1978 Ford 4x4 crewcab. The only problem with it is the gearing in the trans. Needs another gear or the rear end ratios changed. Only winds up to around 55mph.

That's scary because that Ford diesel tech should know that the 6.4 has been retired for a couple years now and the new motor is the Ford design and built 6.7 powerstroke which has been in the trucks for two years now. Ford retained rights to the Powerstroke name. The tech probably only knows the 6.0 and 6.4 because I doubt he sees the 6.7 for anything except oil changes. Go take a drive in the new 6.7 with new 6 speed tranny. Besides not having a cool name like Caterpillar or Cummins I think you'll be very impressed. I doubt you'll find too many of us 6.7 PSD owners wishing for a Cat, Cummins, old 7.3 or anything else. The engine is awesome.

Have seen more than one 2nd gen SD (2008+) badged as an F450 or F550 with CAT/Cummins/Allison combinations up here in CT. Have not spoken with my local truck Outfitter dealer in a few years, but thinking it is available.

Would wait a few years more before committing $$$$ or making statements about any new motors, especially considering the 6L PSD track record.

Why F250? The suspension is crude at best and pre-historic at worst. Too much grill on the present models for me also.

On another note; picked up my boat the other day from the shop (minor winter time maint stuff) and the owner of the boat shop was telling me a friend had dropped his brand new F250 PSD off at the Ford dealership a couple of weeks earlier and had called the bank and told them where to find it. Said the radiator was leaking and the turbos were blown and Ford refused to warranty any of the work. Said they wanted maint records and the guy didn't have any since he changes his own oil, etc. This is all second or third hand info so I don't put a lot of weight on it but the boat-dealer owner swears it was a brand new truck with th 6.7 in it. First I've heard of any problems with the new PSD. Wonder if it's true?

Information I have is you can get that combination, Cat diesel and Allison tranny in a Ford, a Ford F650 that is, I looked in to buying a F650 couple years ago, it was my understanding then that both the Cat and the Cummings with Allison tranny were options.

I fail to see how a radius arm, coil suspension live-axle rig is "crude" or even prehistoric. The design is much, much stronger and more durable than the IFS underneath a comparable Chevy or GMC.

Whats the hype about a Cat motor on a pick up truck? I own Cats on my Big trucks and very happy with them, but I would not let go any Cummins on a pick up truck for any thing else in the market, specially the 7 and 9 litre Cats, is alot bigger than the Cummins much heavier and weak, in size and weight will compare to the ISC 8.3 and the Cummins will do circles around the Cat counter part on power and reliability.

They use twin I-beam on 4x2's. Absolutely crude, horrible design that scrubs the front tires, creates contantly changing caster and camber and is a PITA to align. Because the Ibeam is swinging from a single attachment point, the tire moves in an arc. Because the strut arm swings from a single attachment point, the tire moves in another arc. So now you have a tire that move 2-dimensionally in 2 arcs. Great design! It's crude, AND as far as I can tell offers absolutely no benefit over un-equal length control arms. It's not tougher and it wears out tires MUCH faster. It also becomes a real problem if you put a lot of weight on the rear of the truck via load or heavy trailer (there's those damn arcs again). Because they have an I-beam that swings across 3/4 of the width of the truck, they have to raise the entire truck up to allow room for the I-beam to move under the oil pan of the engine. This means that the center of gravity of the truck is now raised and the vehicle is even more ustable that a normal P/U. Remember the Explorers that flipped when they had a blow out? Stupid TIB on those vehicles raised to CG too high and they were narrower than an F150/250 so they flipped when you had a blow-out. Check the new Explorers out. No TIB on them! Squating the rear and raising the front throws off caster and camber so far that the truck becomes downright dangerous to steer. They got rid of this dinosaur on the F150s more than 10 years ago. Why are they still using it on anything?

As to the solid axle design they use on 4X4s, crawl up under one one day. There's crap hanging all over the place under there. Getting rid of solid axle suspension on P/U's was why Ford came out with TIB back in the 60's... ~50 years ago? So why are they still using the solid axle ~50 years after they invented the "wonderful TIB"?

So what's not crude or pre-historic? And please, please prove to me that TIB is stronger or even lasts longer than ULCA. I've never seen anything that would make me even suspect that TIB is better or stronger.

I have a 2011 F350 diesel. I picked it up in sept of 2010. I have just under 30k miles. The truck is awesome! Best truck I ever owned and I owned quite a few. 2004 F150. 2006 F250. 2009 dodge1500 hemi. I did have a problem with it last month though. The radiator was leaking and it needed to be replaced. That sucked, lost the truck for a week. It was warrantied 100% but I was not a happy boy. Pretty big job taking the radiator out on these trucks and the dealer underestimated the time it would take. All in all I do love the truck, hopefully the radiator was a fluke and thats my last ish for a while.

No, bs on you and your ifs. Especially one with torsion bars. I (not friends or some guy I know) work on construction sites and drill rigs every day and yea ifs does seem to break down quick. We destroyed a 2006 chevy ifs on a rough grand bahama job site within a year and there's a reason most trucks on the sites are dodge or ford. It's called a solid front axle. Keep it greased and it works forever. Theres a reason you don't see ifs on bigger medium and heavy duty trucks. Theres a reason solid front axles while prehistoric are still used every day in trucks, the are tough and simple. Theres a reason all trucks still use solid axles in the rear. Ifs cv joints wear way to easy and ifs generally get loose a wobbly feeling very quickly when used for heavy duty or rough terrain every day because there's too many little moving parts. Yes ifs has better handling characteristics and can lead to longer tire wear due to the ability to completely align them but when it comes to long term durability nothing beats a solid front axle.

Since you don't own a Ford, and are apparently biased against them, why do you insist on populating Ford threads with "some guy I heard of had a problem with his 6.7L Ford" stuff? No value added.
You don't like Fords. OK. You usually can stick to facts. Not here. Nobody is calling your truck ugly, so why sling mud? Believe it or not, it is possible that a new engine design be superior to older engine designs. Gas or diesel. The new Ford is the most modern design in a pickup. It puts out 400hp/800Tq. Time will tell if it is the most durable as well. The reality is 300k miles is probably a reality with any of the diesel pickups. You cannot find real data on repair rates on the internet.
My compadres back at Ford engine engineering report no real issues to date with 6.7L. Unlike the Navistar 6.0L and it's stretched, 6.4L versions.
Oh, on a seperate note, Ford does not own Cummins.

When was the last time you checked about getting a CAT motor in that combination? CAT got out of the business of manufacturing diesel engines for over the road use a while ago. Did this just change? As far as I knew, you cannot get a new CAT engine in any chassis.

It was a couple years back and I did check the Ford website. It appears your options are a 6.7L Cummins or a 6.8L gasoline engine...wonder what happened to putting the 6.7L Powerstroke in it. I think the 7.2L Cat is still offered in the custom F650 and F750 trucks. You used to could only get them in 2wd which is why I did not move on one but now they are offered in 4wd and can be stretched to 6 doors.

You will see a new Medium Duty Ford in "a while" with the 6.7L in it. Regarding durability, most medium diesels are rated as having a B10 life of 500,000mi. This means 10% of the population will have failed at the half-million mile mark. Expect this to continue. This does not mean the engine is warranted for this many miles.

The TIB and TTB were pieces of shit. That's why they did away with them and went back to a solid axles and I-beams. MUCH more durable and when a solid axle cycles up and down it doesn't cause a camber change like the TTB/TIB caused. It was a crappy approach to IFS and Ford realized that they were better off with a solid axle/solid beam design. And no, you obviously don't know what you're talking about. In the 4x4's (I won't speak for the 4x2's because I don't have FIRST HAND EXPERIENCE with them, like you claim to) the Dana 60 front axle is UBER stronger than the crappy GM IFS. Why do you think that GM finally upgraded the "strength" of their IFS for the 2011 model year? A quick example (especially for the guys up north) is that the GM's IFS suspension couldn't hold up to a snowplow in addition to the Duramax. Ford and Dodge had no problems with running diesels + snowplows.

I still fail to see what you're talking about when you mention "crap hanging all over the place down there." Do you mean the two radius arms? The draglink, tie rod and tracbar? The parts that are necessary to keep the axle aligned and what is needed to steer the truck? This is not a complicated design, sorry. Why do you think virtually every major off road vehicle runs solid axles vs. IFS? Because they are much stronger and they can hold up to abuse better than IFS/IRS. No CV's to worry about, no upper control arms wearing out, no torsion bar or tie rod issues. Get off the GM soapbox. And FWIW, I drive a Dodge 2500 and am converting my front 4-link to a radius arm design soon (for off road purposes).

Nope, you're wrong. My son drives a Mercury Grand Marquis (that I bought for him). Pretty decent car and have very few complaints w/ it. Also, since they got rid of TIB on the F150, I think it's one of the best trucks out there and if I ever buy another 1/2 ton, it will be on my short list.

The TIB crap just irks me because other than that, the 250 is a decent vehicle and would be on my short list too. As it is, I'd never buy one. I have less problem with the solid axle on the 4x4, but I've never owned a 4x4 and may never own one - so my bitch is still TIB on the 4x2.

I also like new tech stuff too. Just wary of it for good reason. I waited a year before I bought my Dmax truck and still got one with injector problems. Couldn't wait any longer or I probably would have on that purchase.

From all I know the new 6.7 is a great motor... just wary of it and keeping my ears open for news and was quite suprised by what the boat dealer told me the other day. Wanted to know if anyone else had seen or heard this. Judging by one other post in this thread, they are having some problems with radiators but that's a pretty easy fix compared to something like a faulty injector design.

While the power may continue to climb, I think the major performance period for diesels is over. The EPA has gotten ahold of them and won't let go. The 7.3 was a great motor, but it had its own issues. And it wouldn't pass emissions anymore. Same for the old 6.5. The 6.0's had issues, but most are easily fixed with updated or aftermarket parts now. Same with all of them. But with the dpf filters now and electronic everything, you do have a lot more more things to go wrong.
As to ford and the TTB or TIB, it may be crude and old school, but it still works. You can keep it in alignment of you know how. And it's not weak, look at most stock based desert race trucks. F150's and rangers are everywhere with twin I beams. Amd most of the Explorers that rolled during the Firestone issue were SLA(independent) front suspension. They started using the A arms in 95.

How to not make new allies: "Nope, you are wrong", and then agreeing in text. The emission laws are big time serious as pointed out above. My parent company (OEM) truck manufacturer has $2000 (their cost) in the exhaust system of the diesel pickup. This at a volume of 100,000/year. Scary. Looking at it, seems like looking at some sort of space propulsion system out of the 70's. Fuel injection, additive injection (heated), various sensors, catalyst burn chambers., oh and one muffler the size of a lunch box, all in just the exhaust system. Chopping it off to run a straight pipe would require some serious reprograming the PCM. As always, technology will slowly chip away at the costs to meet the emission standards. Sadly, the emission standards keep moving while the technology is working hard to keep pace.
Soon U.S. emission won't mean much on a global scale as China (biggest new auto market) and India (another few billion people) have their people realizing the dream of owning a car. Probably not a diesel F350 though.

I dont know why everyone thinks the Allison is the Tranny to go with, if you put any power to the Duramax, you have to beef up the tranny, transgo jr, stuff like that, the TorqueShift holds way more power stock... I would love to have a 6 speed auto tranny behind my 6.4L so we could do apples to apples for fuel mileage with the GM trucks... Dont get me wrong I think they are both great trucks, just think the fords transmission is better


I'm pushing 600 hp with my duramax. The one thing I never worry about is my transmission.

I used to party with a 4x4 club that had lots of hp and lift but not a whole lot of aftermarket things done to the drivetrain. Ive ridden in a bronco with the 8.8 rear end that caught fire bc the bearing ceased only ford problem. Ive seen 3 newer GM dive trains die but this was under no normal circumstances but die they did. The EPA is really pissing me off. They even got rid of a bike that I like that got 40 mph wtf?

600hp at the crank or rear wheels, Is that transmission stock, or does it have a few add ons??? TransGo jr?? I'm pushing around 500hp at the rear wheels, but around 1,020ft.lbs tq and doing that with 150,000 miles on it too

I agree completely, and this is coming from someone who has a built Suncoast behind my Duramax.

Also, there is absolutely no way 600hp is possible on a stock Allison. What is done to your Dmax to acheive 600hp?

Sorry guys that was a typeo (I wish I was getting 600). I'm getting around 500. That's at the wheels. Good EFI Live tune, lift pump, and just intake and exhaust.

I heard that Toyota is going to have the Cat diesel in their big trucks for 2013.

If/when this happens, I'll think about getting a diesel truck.
