The Aisin is nice, but the HO is harder on fuel.

Need No.

I vote yes for a better duty cycle.

The 3500 is a beast in any configuration you will be covered 100%, so no worries if you go with the different configuration.

Probably not good for ROI in general if you add in all the maintenance costs over the life of the vehicle. But I'm still in the Yes column.

are you saying aisin is only available with the ho /

That’s correct. To get one, you get the other.

The Aisin has better gear ratios going forward. The 68RFE has a better reverse ratio. I will take forward over reverse. To bad they did away with the 3.42 diff gears, as the Aisin works well with those gears. Love to cruise at high speed at low RPMs. Towing heavy, lock out 6th, however depending on tow speed in TH it will not shift to 6th until a touch over 65 MPH anyway. Maybe look for a clean 2016-2018. I say 2016 as they gain front park sense and ability to move cameras around on displays. AND YOU would still have a CP-3 injection pump!

I've had two trucks with the Aisin, so that's my vote. In 2009, I decided to replace my 02 3500 6spd standard transmission with an auto so my wife could drive it. I researched a lot and decided the Aisin was the transmission of choice. At that time Ram only offered Aisin in the Cab and Chassis trucks. Further research showed C&Cs also have larger brakes, and bigger axles.

Anyhoo, how long you want to keep the truck may weigh in... I kept my 09 Ram 4500 9 years and plan on keeping my 17 Ram 5500 as my last heavy hauler.

Two of my friends tow heavy >15K Lbs with 68RFEs and are very happy. Just about what you WANT versus what you NEED.

Cheers, Ron

I do not want a CP-4.2!!!!

The 68 is a good transmission. With 3.73 it'll be even better. The 68rfe outsells the Aisin probably 4 or 5 to one minimum. Service intervals for the Aisin are cut in half compared to the 68rfe and fluid selection for the Aisin is almost nil. Unless you get it from a dealer your Almost forced to order fluid online. 68rfe fluid is available everywhere and anywhere.

There's no "wrong" choice it just comes down to preference. I certainly wouldn't pass on a good deal either way.

Well said! I'm all about the deal too.

I would vote for the 68RFE and the standard Cummins 6.7L engine. My truck is a third gen with the 68RFE auto, with the 6.7L Cummins and 3:73 gears, 4X4 and this combination has been troubled free for me. I have close to 135K on the OD and I bought this truck to tow a fifth wheel trailer. I am on my third 5er a Cedar Creek 34RL bought new in 2015. this truck tows the trailer with no issues what so ever.

So, I see no real issue with the proposed new truck handling your trailer with the standard 6.7L Cummins and the 68RFE auto.

If I was to purchase a new truck this is what I would purchase. The standard 6.7L Cummins and the 68RFE auto 3:73 gears, 4X4 Mega Cab with the towing prep package.

snow king what is a cp4,2

 

[dieselshadow]

It’s the new style high pressure fuel pump. The cp4 (used in competitors trucks) doesn’t have a stellar reputation so some are vastly scared of the newer version used on the Cummins.

 

[SnoKing]

Grenade! Bosch injection pump.

 

[elephantrider]

you can always get a cp3 conversion from industrial injection if the cp4.2 scares ya.

 

[zb39]

YES!!!!!!!!!!!!!

 

[Wiredawg]

Just for clarity, are there CP4 failures documeted on this website? I check TDR daily and don't recall them. And for more clarity, only interested in version offered on 19/20 Rams.

Likely no worse than injection pumps on 2nd Gen, which I had one replaced.

Cheers, Ron

 

[dieselshadow]

I haven’t seen or heard of any failures or issues either. There are plenty of examples with some good road miles on them as well. This is likely a non-issue.

VP44 failures did not take out the whole fuel system. I did mine myself for $1065, not the 10-12k it cost with a CP-4.2 failure.

You are giving general information.... not saying it's not true, just like you to point us to ALL the failures CP4s are having on Rams, including destruction of the fuel system is all I'm asking. I don't have one, but would in a heartbeat if my 2017 Ram 5500 got totaled or stolen.

I'm just like everyone else, I want to see actual failures.
