'15 Nissan Titan pickup will get new Cummins diesel engine

[RustyJC]

The history and product line of JATCO is pretty lengthy - see HERE. They supplied transmissions to most all of the Japanese manufacturers, including Honda.

Not sure if it was mentioned previously or not, but I was at SHOT Show in Vegas the past few days as "media" and was able to talk to the Cummins and Nissan people regarding this new engine/truck.

Peak torque will be between 1200-1500rpms, not a high revving engine. Rail pressure will be approx. 32,000 with piezo injectors or as they said, "the next generation of Bosch fuel injection systems. He couldn't remember the type of fuel pump. Both the pump and turbo will be in the "V." The turbo will be a Holstet, but they aren't saying what the specs are only that it will be "very different than the VGT found in the 6.7L."

Most interestingly, the transmission... I asked if Nissan were building one in-house and he said "sourced through a third party that Ram HD owners will be familiar with." I asked, "Start with an A." He nodded yes but possibly some "improvements" being made to it.

This post is very interesting, the V8 Cummins/Nissan is sounding more advanced than I first envisioned, and brings up a point that I think many light truck buyers are facing.
I'll try to explain, and hopefully not go too far on a tangent:

You know I like my 2 Dodge-Cummins trucks, and the 2014 is a very tempting platform...in some combinations. But really, Ram needs to put the Aisin in the 2500. When I look at the 26000 GCWR CDL required issue in my state (and many others), and see the GVWR for a 4-tire gooseneck trailer is commonly 14000 GVWR (and often 16000 lb), many buyers will want a truck at or below 12000 GVWR to avoid the CDL hassle. If a buyer wants a crew-cab with an 8' bed to avoid clearance issues with a deck over the gooseneck, gn-car-hauler, or similarly nosed trailer, then the Ram choice becomes a 2500 without the Aisin.

Disappointing that GM offers a 2500 with Allison 1000 (330 lb), Ford offers a 250 with 6R140 (350 lb), and Ram only offers a 2500 with the 68RE (235 lb). Heck, even a Nissan 1/2-ton might be equipped with an Aisin transmission!

A hundred pounds of extra strength transmission in a vehicle likely to see a trailer weighing 14000-16000 pounds (or even heavier RV) is a serious consideration. Ram has an otherwise class-leading 2500, but I will not buy it without the Aisin. I had to bail on a 2500 with the 47 auto, and baby my '03-48RE to the point it is not towing my heaviest trailer. I tow my heaviest trailer with a '97 3500 manual, all the while hoping to avoid stop-and-go traffic that the best automatics reliably handle. I will not buy another 2500 with an automatic transmission that is not the equal of the engine. Too bad, as the 2014 2500 is an otherwise stellar package, and the new rear suspension is quite an achievement.

How about it Ram, let's put the Aisin (or another transmission built to the 330 lb strength-standard) behind ALL Cummins/Ram trucks.

Should I even point out the fact that GM chassis-cabs get the full strength Duramax now? GM must have full faith in the Duramax/Allison!

If your truck and trailer are capable of 30K GCW, but you are operating at 24K GCW you have to have a CDL in your state?

That means that to drive a '13 3500 DRW with 3.73 or lower you would need a CDL, even if you were empty going to the grocery store. Or a 2500 with a 48RE and a GCWR trailer of 1,000 lbs would require a CDL.

Not saying it's wrong, just doesn't make any sense.

Look at the FMCSA rules:
http://www.fmcsa.dot.gov/registration-licensing/cdl/cdl.htm
In short they take the truck GVWR plus the trailer GVWR and add them together. If you have a 14000 GVWR trailer (not RV) towed by a 14000 GVWR 3500 truck, you need a CDL in many states, including mine, and it doesn't matter to them if you ACTUALLY weigh less than 26000 combined, they go off the combined RATED weight.

I don't think it should be that way, but that is the federal regulation. Some states allow a "non-cdl" class A license, such as IL, and there are some other wrinkles for trailers below 10000 lb behind a truck weighing up to 26000 lb, but there it is. My state allows trailers greater than 10000 lb GVWR without a CDL as long as the RATED GCWR is less than 26001 pounds.

http://www.itd.idaho.gov/dmv/DriverServices/documents/cdl_manual.pdf
page 14-25 will give you an overview of your states rules and exemptions

"GROSS COMBINED WEIGHT RATING (GCWR): The
GCWR is the total weight of the GVWRs of each unit of a
combination vehicle (truck/tractor and trailer(s) added
together."

"You must have a
CDL to operate any of the following commercial
vehicles:
Combination vehicle with a gross combination
weight rating (GCWR) of 26,001 or more
pounds, provided that the gross vehicle weight
rating (GVWR) of the towed unit is greater than
10,000 pounds."

You got off subject matter. OK, they have a 7 speed for heavy rwd vehicles from JATCO. does not say if it is a CVT, but maybe it would act like one. with a 7% fuel mileage increase. Quite a trail that company lead, from then till now.

Off subject?

JATCO builds standard automatic transmissions (is that a contradiction in terms?) as well as CVTs. I had a JATCO 5-speed automatic in my 2003 Acura 3.2TL-S. It was not a CVT. CVTs have pretty low torque limitations because of band strength and band/pulley slippage issues, so I doubt that they have a CVT on the shelf that will live behind a diesel.

Yep, cdl's don't equate to nissan Titan.

Was going to comment --thanks DFitzwater.

Was going to comment --thanks DFitzwater.

How is it even possible to get off subject in the Dodge-Ram TDR Forum for "4th Generation VM Turbo Diesel 1500" in a thread titled "'15 Nissan Titan pickup will get new Cummins diesel engine"?

Not that I care about off subject, and am even interested in following a discussion on CVT's but how is a JATCO 7 speed even a CVT, or not "off subject"?

OK, carry on!

 

[AH64ID]

I would say it has to do with potential offerings with the topic of the thread...

The whole thread is off topic if you look at the forum.

 

[DonFitzwater]

Because they may be installed behind the new cummins that Nissan is going to use.

 

[PDM]

Yep, cdl's don't equate to nissan Titan.

It's the TDR forum titled "4th Generation VM Turbo Diesel 1500" so aren't we already off subject? A CDL discussion isn't any more out of place than one concerning Nissan is it?

I had thought we were free to discuss any topics of interest to diesel enthusiasts, and a Nissan-Cummins-Aisin towing a trailer over 10000 pounds may require a CDL in states where posters on this thread reside.

OK, guess I'm color-blind to the thread boundry, but I'll try to look for it!

Since were still off topic, is everyone in Wisconsin wound this tight? Lol

 

[PDM]

Was just surprised by the hall-monitoring, not something we see much in Wisconsin. If it makes anyone feel better, I too get frustrated around many of the CDL discussions as there is so much incorrect information that usually follows.

Getting back to the Cummins V8, read a little about the sequential turbo setup at http://www.dieselpowermag.com/ and it seems that more development has been done for the Titan than I expected. Looks more likely to be a well developed vehicle.

hall monitor!!!

OK, thats funny!

Put a cummins in a truck that won't totally rot out in half the lifespan of the engine and make it fairly affordable and I will consider buying my second cummins powered truck.

For now everyday I walk by my recently vp44 dead and long time body rotted out 99 Ram and remind myself of better days driving with "HVAC" many moons ago in his rocket red Ram. A new Ram outfitted like my 99 is twice the price now. Where is the sanity in that and will it last any longer?
