2015 auto or manual trans?

[jkalchik]

I understand that, probably better than most, which is why I shot it from only a few inches away, and knowing that the exterior casing will be cooler than the internals. If you're getting a 100+ degree F difference in temp from oil to casing, I'd suspect that you've got something else going on.

snip... Didn't the Ford manual have a cooling system using the radiator like an auto trans would? I saw a picture of one, just don't remember the trans model.

The later 6-speed yes, but not the 5-speed ZF.

I used to limit my rpms low, around 2200-2300, but now I will tow at 2500-2600 if needed and the engine is much happier. I don't always rev it that high but have no issues if it is needed.

Agree with this... at lower loads I don't mind/like running lower rpm = better mpg, etc. If I need to gear down I will, and I'm not shy about using the whole rpm range on any of my engines. I don't keep the engine spinning in the stratosphere, but there is a rev limiter for a reason.

However, I still prefer how a manual doesn’t downshift early or needlessly, depending on the terrain. I can see ahead but the ECM cannot. To argue in forever of the [taller than I prefer] 3.42:1 gearing— it won’t pull hills ‘with a load’ as well as my old 4.10:1 manual, which forces me to go down to direct sooner, which is better for the rig overall, even if it cost a little fuel.

I've never checked with an IR to see case temps, and your right about the difference wouldn't be 100*. I only use my IR when testing AC registers that confirm the AC unit is in heat or cool. I've never checked oil temps until after the SMF was installed with the oil coolers from Geno's Garage. The oil coolers they sell have the 1/8" NPT tapped already, so I have two installed and when climbing with a load there is a 5-7* difference in temp from the passenger side to the Driver side. I found in hot climates the oil coolers are not effective and climbing out of Palm Springs with a 30mph head wind and 90* ambient, the trans would easily get to 230* with the hottest I ever saw at 250*. So that's why I developed my cooling system.

Ok, I thought I saw the cooling system in a pic, and that started me on the cooler idea, that started my quest on developing my cooler.

I can't say what the Aisin would do, but the 68rfe is too clunky in T/H and I keep it in drive, unless it's bumper to bumper then I pick my gears. The G56 is fun to drive but the 3:73 is to tall for my 305 HP 6.7 C&C at the Comifornia 55 speed limit with trailer/5ver, and it causes me to constantly shift up and down, I can't imagine what it would be with 3:42's.

Who really tows at 55 MPH? Not the trucks for sure, they seem to roll at 59-60 MPH. SNOKING

 

[RVTRKN]

Yes, that's right, but that's about it and 60 is where I run when with 5ver in Comifornia, other wise it's 65-70 mph and puts my 6.7 CTD in a sweet spot. It's the rolling hills that kill me heavy at 55-60 mph.

 

[Cummins12V98]

I tow 60-62 in CA with no trooper problems at all. Slowly passed by several of them.

 

[K9Kodi]

I've had 2 precious 68rfe trucks and it took me a while to find the one I just bought, bc it has a g56. I had transmission issues with the last truck, constantly bumping 2/3 gear, yall know shuttle shifting. It was annoying. Then to think about all the automatic clutch surfaces and how clutches are a wear item, no thanks , rather do my own manual clutch in my driveway then send off a whole transmission.

Be very careful about loving the g56 on this forum. This forum is really only for aisin owners.

Is there a subscription to renew for this forum?

The TDR magazine, yes. Heck, I've only just begun to praise my manual transmission in my column, and don't mind being in the minority, love me some manual control.

Love my manual transmissions, just not the G56. They are capable, just are inferior to the NV5600.

I dont get it, I thought this was a great conversation about a members quest to pick his transmission option. I wish this thread was in late 2006, when I was researching for my C&C, when the G56 was first introduced in late 2005. I probably would have picked the G56 anyway, but at least I would have had an understanding of the differences.

Apparently, you didn't have the privilege of posting with TDR member HBarlow, even though he had a treasure trove of knowledge about commercial hauling, he was a stuburn, pigheaded & had a "my truck is better than your truck" complex. He was rude and would get personal if you didn't agree with him. We'll miss your insights and opinions, as they say "the grass is allways greener on the side", good luck with that.

The New Venture is dead, buried and gone and OE parts are almost none existent.

Here's a POLL that YOU posted back in 2009. Seems like lot's of G56 owners were and still are happy with the transmission. https://www.turbodieselregister.com/threads/210353-G56-Poll?highlight=nv5600+failure

 

[RVTRKN]

Blumenthals now manufacture parts for them.

 

[RVTRKN]

That poll I posted due to the misinformation at the time, and was hoping for clarity.

Milk that stock clutch as nothing's as smooth and quiet. Operated within the stock parameters should yield a long silent life.

Impressive thread.

Agreed. While I'm not really a fan of dual-mass flywheels (the one on my 1996 F-350 died early but the clutch was fine), the engagement, feel, and control of the OE clutch on my '14 2500 leaves nothing to be desired. At least with only 12,000 miles. I'll replace it when it needs it or fails, but I'm betting I can get several years and many thousands of smiles out of the the OEM stuff.
