G56 Update

[photowrite]

So I want the most hp and tq from the factory with the G56.

So reading these posts the auto with the torque management only allows full torque at the right time under perfect conditions?

The G56 has full torque control with the go pedal?

Are there any dyno runs sheets or specs that show when the torque kicks in?

Thank you Casey

With your experience, I bet with a back-to-back test drive you would be able to feel how much or little difference there is between the G56 and an A/T and the perceived power.

One of the things I like about a turbo, manual trans... Is even though momentum is lost when changing gears, losing rpm, and boost, when all comes back up after you tip back into the accelerator, the full-surge and 100% lock-up of a manual really makes the twist noticeable... true on the my new Ram, old Ford, and our VW TDI.

Besides the torque mgmt, I'm guessing the EB works better with the G56 as well. I've been reading the the EB doesn't work under 20 mph on the auto transmission. That would irritate me as I was always using the EB on my 04.5 at slow speeds.

Yes!

I've been impressed with the factory exhaust brake... Works down to about 900 rpm regardless of road speed or the gear selected.

That momentum loss is something I could live without. The only times it got my goat was when I had to start off up hill when I really had my truck loaded. I always thought, "Wouldn't be nice to have an auto".......

Been there, done that.

Agreed, loaded and up hill shifting can be a drag

The manual transmission trucks also utilize torque management, and they have for a very long time.

There is more than just the transmission that cannot handle the full torque in first gear.

Well, that makes sense and seems reasonable. A skilled driver focused on "vehicle sympathy" wouldn't lay into it like that anyway.

Yeah, it's as bad as the auto's but it's still there.

There is a reason that the people that jump from 12V's to CR's feel like they have less power off the line under certain driving.

I can tell you that when I first drove my '07 after having a 98.5 +100 hp engine and DTT transmission,it was disappointing to say the least. Smarty helped a lot but the power is still not linear like my old truck. Hopefully,EFI on the way after taxes. Looks like EFI on the way for the 4th gens.

There have a been a couple times at low rpm in 2nd or 3rd when I leaned on the skinny pedal that I thought the engine seemed to build torque slowly. I was just blaming it on slow/low boost, but maybe it was toque management.

The manuals do not have different output for the lower gears. There is torque management for all gears. The computer TELLS the auto trans what gear to be in so it CAN detune the engine, it also tells it when to shift, another detune. The computer can only CALCULATE what gear the manual trans is in by engine RPM and the VSS, there is no sensor that tells the computer what gear the manual trans is in. With the torque multiplication of the manual trans in first gear, transfer case in low range, even a small gas engine can overload the drive train. What saves it is the loss of traction, the wheels spin before things brake.

Cool and interesting.

What I was saying was that 2-3 is when I thought I felt possible lower power/torque management. I've never thought it was managed on the top end or higher gears...but I guess it is. I don't need or want torque-management, but it's possibly a good thing to have for those infrequent times when somebody else drives my truck.

I don't think my truck is sluggish, I like how the truck drives with the G56 transmission, and even the 3.42:1 gears that I thought would be too tall, no complaints. We shall see when it's loaded, but I don't expect to be disappointed.

There was a big difference in emissions standards between the VE, P7100, VP44, 5.9CR and the 6.7CR. that is whey they all drive different. The 12 valves did smoke a little is stock form, the 6.7s wont even soot up the tail pipe in stock form. I remember how much people hated the 24 valves when they first came out, even though they has higher ratings they drove so different everyone hated them. The CR all had torque management for lower output at lower RPMs the engine was capable of making much more but for various reasons we where not given everything the engine was capable.

I read the Ram Truck Cab and Chassis website that the Aisin is rated for 325hp and 750 ft-lb and the G56 was rated for 320hp and 650 ft-lb. That is what I read anyway. I am still leaning to the G56 after a 2000 Ram 2500 and 2004 Ram 3500 with a combined 530,000 trouble free miles with their respective NV5600's.

 

[Joseph Donnelly]

That was the AS68 Aisin; the AS69RC that Ram has used since 2013 is rated much higher. Also the G56 has nothing in common with the NV5600.

The G56 is no NV5600 and unless you had both you can't imagine what the difference is. The NV5600 takes a few thousand miles getting used to shifting it but once you've dialed it in, its a beast. The G56 on the other hand is a very easy trans to shift, almost feels like your in a car with a manual, BUT, its a piece crap and will bite you in the wallet if you don't take proper care of it. The first thing you should do is dump the ATF for your favorite brand of manual transmission oil. the second is to over fill it by one quart. If your like me, I've been proactive with it by adding a proper transmission cooler on it at a ridiculous cost. I really recommend the Aisin as long as the G56 is the only manual offered.

Just a little side note, I have never liked the way my G56 has shifted. It's loosened up some now with some miles on it, but I always felt that the NV trans in my former '01 was much nicer.

Joseph: let me rephrase it as on the cab and chassis models you get 325/750 for the Aisin and 325/750 with the G56. On Ram Trucks(non cab and chassis) you get 385/865 for the Aisin and 350/660 for the G56. I know the G56 is no NV5600 and that is why I am on the fence between the G56 and Aisin. My next work truck will be cab and chassis 3500 SRW 4x2 crewcab and used for lugging tools and parts around to differnt job sites. There will be very little towing involved. I have driven the G56(test drove new 2500) and was unimpressed in shifting action. I also drove an Aisin cab and chassis 3500 and was impressed how it operated on the short test drive. My last auto equipped work truck cost me over $7000 in repairs in 140,000 miles.

I'd get the Aisin if I were to order today.

I think I would too... just for the power.

I really don't think the G56 is as bad as everyone wants to believe. It's been in operation for more years than the NV5600 and with more power.
