Aisin transmission and defueling in the lower gears 1-2-3 ??

[AnonEd]

Do the DRW 3500s have traction and stability control, and if yes, were they turned off?

 

[Cummins12V98]

I had turned it off.

 

[JPM]

JPM, what are you asking or saying???

one guy says the new trucks spin tires and other says they do not , so what is it?

I can only comment on the 19 HO DRW I drove at May Madness, it did NOT. Honestly felt just like my 15 HO.

Much more get up in tow haul mode

Hauled a double axle heavy duty hydraulic dirt trailer today. Small track hoe and several loads of dirt up the mountain for my fishing buddy. New truck has lots of power. First real work its done. I’m impressed awesome power

TH keeps you in the power band.

TH keeps you in the power band.

Thats not really true. These aren’t 2-strokes.

Thanks to the displacement, VGT, and programming the power band is wide. You are very much in the power band without TH and an empty truck.

You may like the response of being in a lower gear when empty, but that’s not a power band issue.. that’s a response preference.

The way these automatic trucks are programmed you simply won’t run out of the power band, as the shift programming keeps you there.

I generally dislike TH empty as it’s doing nothing but over revving the engine and burning more fuel than required.

A loaded truck is different based on the power required is higher.

 

[Cummins12V98]

Personal preference, call it what you want you have instant acceleration in TH. Burns more fuel yes but who cares.

“Over revving” not so that’s if you exceed 3k.

I have instant acceleration without TH, and plenty of people care about burning more fuel than needed.

and typical example of a selective quote... over revving referred to required, not redline.... do you work for the modern media?

Let me clarify it. The 2020 HO's I took for a test drive slipped the tires less than 10% the moment the go pedal hits the floor from a stop. You can hear tire slip with the windows down. It's not a burnout. I came real close to taking a 2020 DRW Longhorn home because the SRW I wanted to see had sold before I arrived. Just couldn't talk myself into the DRW, and at that time, a S&S CP3 conversion OEM warranty question. (I drove both the DRW and SRW 2020's.)

My 2018 HO applies power much slower. Takes more planning with delayed power pulling out in heavy traffic.

My DRW 15 AISIN right out of the box handles my 35k combined load without any modifications. That's West Coast Towing!

Did same with dead-stock 2005 G56 DRW in oilfield. So?

15's for a 2022 and 17-18 for a 2003.

Your ET math is also off. Not sure how you're calculating it, but it's hard to prove a point with incorrect figures.

300hp @ 7000 lbs is a 16.6 ET; while 400hp @ 8000lbs is a 15.8 ET.

Noticeable braking improvement on my 18 over my 05, and that's just the service brakes.

I can pull better mpgs out of my 18 than my stock 05, so again poor figures. My modified 05, which returned better mpg than stock as well as a lot more power, could do better in some instances than the stock 18, but not all. They are generally ±5% which is hard to quantify as capability vs environmental.

Speed and braking are just one aspect of towing, handling is another and the 18 is night and day better than the 05, which was great too.

I cited published test review numbers.
Then a 1/4-calc. No significant difference.

— Where’s the braking numbers? At a minimum: rotor swept area comparison vs weight.

— Faster thru a slalom? (Won’t be).

I’ll stay with my assertion that at a minimum the latest CTD exact a $10k penalty atop all else.

Lowered cost of operation is nowhere in sight.

Here’s a ‘16 in the hands of a conscientious driver. Harder, granted, to match ‘04, but it’s not an improvement.

A). Class 8 has more power and burns less fuel than in ‘04.

B). But these little light-duty pickups today do practically the same as they did in ‘04. They aren’t better on the road, nor can they do more work.

Some might say otherwise. Fine. Where are the offsets to total cost of ownership & operation as would be shown in CPM?

— I got started down this road wondering why my quarter-million mile truck is now worth close to as much as I paid for it fifteen years ago in unadjusted dollars.

The “answers” weren’t hard to deduce.

I think some folks might think something is wrong in the transmission or engine as it feels like it falling flat on its face then comes back on gang busters later. Truck is meant to pull and haul not drag race with . I need to try to drive it normal. I probably really need a hellcat hemi. Need for speed

Agreed. It’s limited by a design that hasn’t changed in about 80-years.

A 1943 Willys and a 1993 HMMV aren’t in the least the same.

But men today don’t make even half of what their fathers made fifty years ago in re buying power.

That might have a little something to do with it.

Apples and oranges.

Oil field work is mostly slow and on flat ground with a low profile load. Take that stock '05 with a high profile 5th wheel, in the mountains of the Rockys or West Coast with no exhaust brake.....

Or, take that antique G56 in stop and go traffic, down town Denver, for 60 miles with a heavy load v/s the modern 4th gen. auto....

I love my old standard transmission Cummins powered trucks (3) for the log woods, but for the big highway, gimmie my 4th gen!

That'll be me... having drove my 04 and towed with it all over the country,. my 2020 is lightyears ahead in comfort, power, and not much of a penalty at the pump. I dont miss the 04 at all except those rare occasions when it would be nice to have a second truck around and the Bronco doesn't cut it.

I guess I could be a smart AZZ and reply the same to you but not worth the ink.

What's the deal? Seems like a lot of attitude on here at times!

Two different applications. Hook my 6k pin and 24k RV to that and see if it sets ok "STOCK" without airbags. Not to mention miles long 14% grade holding it to the floor and not getting hot. YEP I have done so locked in 2nd and down the same 14% locked in 2nd with no brake applications other then for a sharp corner.

Yes only way my tires break loose is on wet or loose ground. TQ management protecting it but I think it is just set too aggressive.

 

[Wiredawg]

The 4/4.5 Gen Ram trucks are just amazing... I still find the performance and hauling/towing numbers to be unbelievable. My only suggestion is the 2500s ought to be available with the HO motor. I'm loving my 5500 since I'm driving it more.

Cheers fellow Rammers!
