Went to look at a RAM 3500 today with what I'm towing and the AISIN trans and 6.4 I thought I'd take a look. Had my title and was serious. Wow what a unrefined power plant IMHO Started 2 both had knocking for first 30 seconds then settled into sort of a rumbling idle almost like a slight miss. Drove one plenty of power but came back and started my 6.2 what a refined smooth engine in comparison.
This is just my IMHO based on short experience with al the rebates over 9,000 + discount was over 10K off truck about 36K with tow package and everything I needed. Compared to my XLT felt cheap and unrefined in terms of trim wasn't bad going down road. I'm happy where I'm at even with a screwed up synch system for last year and a half. I just couldn't go down the Ram pathway.
My ford dealer is getting Ford involved 22 service calls on it new Radio and not resolved During the last 13 months. Dealer knows i have a problem dropped calls, Radio just shuts off, switches to AM, Phonebook Corrupts all documented. I've had a fusion and 2 other Escapes on lease all flawless. Not sure how to resolve Customer Care no help did get Ford Extended Warranty at NC but still broken. I love my 6.2 Quite a motor

 

You can't get the AISIN with the 6.4 Hemi, only the cummins. The new 2019 Ram 6.4 Hemi comes with the ZF 8spd matched for the Hemi, from the reports I've read it is a major performance improvement. The exiting 66rfe tranny mated to the 6.4 was just not a great match.

 

We have quotes for fleet trucks in a 3500 Dually 6.4 with the AISN trans. They have a lot truck with one but it was 4x4 and we wanted TWD. Now when I tried to build a truck on Dodge’s website selecting that trans automatically moved me to the Diesel engine and i thought the same thing but that is not the case according to our dealer.

 

The 6.4 and Aisin is a C&C only option and not available on a pickup truck.

 

Ah yes, this makes sense. Good info.

 

I looked at 2 Pickup yesterday with them PDF of Sticker is Attached 66RFE is AISIN on 3500 with 6.4

 

The 66RFE is not a AISIN transmission.

 

to each his own...went from a 6.2 to a 6.7 Cummins Big horn trim....28,000 miles no issue and love towing with it.

 

My bad 66RFE is not AISIN stand corrected

 

Wow. I test drove a 2015 leftover in 2016, and it had the same knocking. Research on the Ram forums said it was a pretty common issue with them. Good to know Ram cares enough about the customer to fix it after all these years....not!

I had a 2016 Cummins. I do miss that engine (and the manual transmission), but I don't miss the emissions issues and maintenance that come with diesels...

 

I have had the opposite experience. I purchased a new 2017 2500 with the 6.4L and now have 18,000 miles with out a single hiccup. The engine does not make any funny noises, the transmission shifts very smoothly, the ride is over all pretty good. The front suspension does not have a lot of travel so if you hit a large bump/pot hole the suspension bottoms out the stops and really jars you. For a large pickup I feel the fuel economy is pretty decent, I pull a 13K 40 foot long 5th wheel a couple of times a year and it does it very well for a gas powered rig and gets decent fuel economy doing it.

I have been a long time Ford pickup driver and fan but my 6.4L diesel was starting to show some signs of needing major engine work at 170,000 miles so it was time to get rid of it. I took it to Ford to buy a 2017 F250 with 6.2L gas and they would give me very little in trade on my 2008 King Ranch coupled with no discounts on the new body style pickup so full sticker price. Took it to Dodge who gladly gave me 7K more in trade and big discounts on the Ram and it was 16K cheaper to buy than a Ford so I went with it. It is a Laramie trim package and the Ford I was looking at was an XLT. I showed the quote to the Ford dealer and said i'm leaving town today in an new pickup so which one will it be, you are going to have to match the trade value at least before we can even talk and they said nope, nobody wants a 6.4L diesel.

I'm not here to start a fight but the comment about Dodge doing nothing about the noise on the Hemi, is that kinda like Ford did nothing on the MOD engines that spit spark plugs out or the later MOD engines that you can't remove the plugs from? Should we venture down the road of complaints on the 6.0L diesel? Dodge is not the only one to ignore fixing major complaints and doing very little besides give a little discount to trade on another new one.

I still like Ford pickups but I wasn't going to pay a premium of 16K to drive one. I still own older Ford pickups for my farm and for fun and I am sure I will have another new one again some day. For now my Dodge does everything I want and more and have no complaints about it.

EVERY single dodge owner I know says the same thing. The cummins engine is the good part. Everything else around it is bad news.
I don't even know why people drive a dodge gas truck. That's like the worst of both worlds (engine/rest of truck).

YEah Ford's 6.0's were garbage. Same for 6.4. 6.7 seems to be better. Stille expensive.

fyi, the spark spitting issues was a simple fix; torque it to 26 ftlbs.
The spark plugs you 'can't remove' isn't bad at all. Run the truck to warm it up, remove w impact wrench. Works very time. Even if it breaks off, there's tools.
