Aisin transmission vs others

[brillmtb]

So I moved to looking at the 3500 to get the Aisin as I felt the weakest link in these diesels has been the stock auto transmission. I would be happy probably with the air ride 2500 then the air ride 3500 was an option but now appears to offer little advantage over the stock spring version as the ride quality doesn't seem to be that much better. So now I go back to asking myself is the Aisin REALLY that much better to give up on the 2500 air ride and sink thousands into the Aisin +/- the air ride on the 3500. I think going from an 03 HO to a 800 ft lbs motor in the 2500 vs 865 in the 3500 is probably a minor point.

I also read in another thread that the exhaust brake decides when to come on or not. Is that true, is there no "manual" control over them now?


Thanks

What are you going to do with the truck?

My exhaust brake works all by itself and does a fairly good job of it. It doesn't do much once the speed drops below 30 but anywhere else it slows big loads with ease.

If you want a comparable replacement for your current truck, the new 2500's will far exceed what it is capable of doing and in far greater comfort.

I haven't run a truck with the Aisin yet so I can't offer you any opinion other than my 68rfe tows like an angry freight train and is trouble free so far.

The air ride suspension between the 2500/3500 are completely different. The air ride on a 3500 is nothing more than a modified leaf spring w/ Firestone air bags; actually says Firestone on the bags.

Both auto transmission's have been out for a while and are proven. If I end up buying an auto transmission, I will seek the Aisin. My thought was if Ram continues to use the Aisin, it will carry a higher resale value later on. This of course is an assumption.

I'm still bewildered that Ram is offering 3 different transmission options to begin with and I think it stinks that the a Aisin is only offered in the 3500's.

Get The Aisin..... Now if all you do is Drive to-fro form the lake campsite... the 68RFE will work ..but its NO Aisin 69RCS. Both My 3500s with Aisin and Riderite (15PSI) @$350.00 ride nice.... If you want the best ride Buy the 1500 Ecodiesel and 4-point Air Suspension.

Depending on how heavy you plan to tow would dictate what auto transmission to buy if this was me. If you are going to pull heavy than you will need a dually truck also. So if you plan on pulling a 11K to 14K GVW trailer than the 68RFE auto transmission would be just as good as the AISIN transmission would be in this application; and save you some money.

I have the 68RFE auto transmission on my truck (the only one offered until 2013.5) and the transmission has been very reliable to me. I now have 80,000 trouble free miles on the truck with the only maintenance done to the transmission being transmission oil and filter changes. I do have the Mag-Hytec deep transmission oil pan installed with a temp gage on the auto; temps when towing my 11K fiver have never been above 180F with the pan installed.

The transmission is also seeing additional horsepower than stock I am using a Smarty S67 set on level 3 which is 60HP over stock at the rear wheels and torque management set on level 2. The truck has been this way since I installed the Smarty at 15,000 miles on the OD; so I have driven approximately 65,000 miles this way.

It is your call and money but to me the 68RFE transmission is no slouch in the right application. It is not like the 47/48 series transmission that was used on the 5.9L Cummins engine.

60K on my 68RFE towing a combined 27-29K and it has performed flawlessly!

My 15 on order will have the Aisin mostly because of the higher power.

2500 and 68RFE you are good to go. Personally I would never own a 2500 since 3500's are not much more and they are far more capable.

My 48REs I built, 1 Goerend (sold several Goerends over the years) 48RE all transmissions pulled 24 to 31K daily for 104k miles on 1 (Commercial) 78K on the other , the Gorend still pulling for New owner at 171K .. but none of these transmission will out perform My 69RCS You can make claims like these but they still are NOT equal to the 69 Aisin. Its this simple Ram test the transmissions before production if the 68RFE had the balls of the Aisin it would be in all CCs, like the 6DR110 Ford makes in 250-650 Trucks. that 6DR110 is 1hellva trans.

I see the running programs (background) that saving $3,000.00 makes you feel better...Thtas OK, but thinking and promoting the 68RFE is equal to 69RCS the is ****************9*0-%-0

The AS69RC in my '13........sold me the AS69RC in my '14. I'm at 60k miles on my '14, and it's not skipped a beat.

 

[RustyJC]

I don't believe people are saying the 68RFE is equal to the Aisin Seiki AS69RC, but neither is the 68RFE a POS! In my (and others') experience, it's proved perfectly adequate for our stock trucks pulling some pretty darned large 5th wheels. Yes, I would probably order a new truck with the AS69RC because more is always better (!), but it's not because the 68RFE in our current truck has performed anything other than admirably in 90-95% towing service.

Ok TC, I'm calling you out on this Bull sheet, who is comparing the 68RFE to the Aisin?

 

[Wingate]

I would look at RAMs Towing Guide... Look at similar trucks with the two different transmissions, there is a SIGNIFICANT difference!
If you will never need the capability of an AISIN then by all means, save your $$$ and get the 68RFE.
I purchased the AISIN because I want it bulletproof no matter the situation. I am NOT easy on my truck, even when towing... I do not have the patience for the 68RFE, Im not going to be gentle on it....

 

[TCDiesel]

OK... Name the place We will GVW the trucks Equal GVW Mine's 9258 Full tank or full... Make yours the same or I will add to My GVW.... Unlimited engine mods allowed. Factory Trans, (that's what were testing anyhow) Hook up and pull until the death... Up you want to make a $$$$ side Bet I'm in. I will be in West MT next month ,How about some place in Washington State, My Visa expired so I can't enter Canada.

Do you really not understand what we're saying? Nobody's claiming the 68RFE is "EQUAL TO" the Aisin. What we're saying is that the 68RFE has performed just fine for many of us who have stock trucks that tow some pretty substantial loads. I don't understand why that's so difficult to comprehend.....

[DonFitzwater]

TC, you just don't understand what is being discussed in this thread. You get off on some strange rants man.

 

[TCDiesel]

I apologize .... The 68RFE is a good trans I'm Not disputing that.. I have 1 of the most powerful pulling truck in America, I live and ****** pulling and when someone mentions call out I raise to the occasion and if I get my but kick I tip my hat and all is good. I'm not off on some social web Rant... You mention the words call out can get a man in a whole lota crap. It also means different thing's to different people.

Maybe I'm just putting to much into what's type.

Solo or towing, the Aisin is just laughing at the load. As the warranty guru said to me when I was choosing: The 68rfe is much improved and probably adequate. The Aisin doesn't break. The Aisin also has a steeper first gear, making the 3.42s more practical for us--we get the mpg and the takeoff with a load. You are getting too good an engine, the Cummins, right? Why not get too good a transmission as well?

 

[Cummins12V98]

The same "guru" told me to leave the 3:42 gears if I was happy with the performance. I have been extremely happy with the 68RFE and 3:42's pulling 27-29K. He told me it won't hurt it's self!

I will be even more delighted with the 4:10's and the Aisin towing my new 39' MS with the new 15 on order.

 

[2014 Ram]

Just curious as to the HP and Torque the 98RFE can handle comfortably with engine mods...

Awesome...I'll be looking forward to the review on the 15..... when its coming?

 

[brillmtb]

Thanks everyone. I am not easy on my truck either and I too want a bullet proof transmission so I think I will go 3500 Aisin and dump the idea of air ride and go with the standard springs.
