2007 6spd auto trans
Does anyone have some info on the newly advertised auto 6 spd to be used in the 2007 3500 truck? I understand it is Japanese made but don't know much else. Wonder if it will be much better than the 48RE?

Just curious - why the thumbs down icon if you don't know anything about the transmission?
I understand it's built by Aisin, who also builds transmissions for clients such as Toyota. Here's some info from the coverage of the 2007 Ram 3500 Chassis Cab introduction.

The optional transmission is a six speed Aisin AS68RC automatic with a .63 ratio overdrive and 4.10 rear end gears only. I've included pictures of the cutaway transmission that was on display. As you can see in the pictures, the torque convertor is a multiple disc lockup unit. It is rated for exhaust brake usage and is a fully electronically controlled transmission. We asked if this transmission was going to be used in the regular 2500 and 3500 trucks and were told that the '07 model will continue with the 48RE.

Doesn't Toyota own 20% of Aisin-Warner ???
FWIW, Aisin Warner units use the Aisin Warner T-IV ATF and not the ATF+4. You'll have to buy it at a Toyota dealer for about $5/qt; Amsoil makes it in their Universal ATF though.
But, they may be factory filling with the new "World-Standard" lifetime ATF in Aisin Warner units, I don't know to be honest. Starting with the '03 4-Runners, Toyota switched to the World-Standard fluid in their trucks. Its supposedly a lifetime fill (similar to Toyota T-IV), but costs $10/qt.
60K drain interval under severe service, and lifetime fill under normal service.
Sorry for the hi-jack.

I'm taking a wait-and-see approach to the whole 07 deal. Aside from the transmission, the engine will also apparently have quite a few more sensors, electronics, particle filter, EGR system...
Could be good, but I think I will wait until they have been out for a while.

No body knows what the affect the new epa things going to do to the 07 diesels. There is one thing for sure. The cost of the truck will rise a great deal with all the added epa garb and the mpg will drop. I can tell you this. If I were in the market for a new truck. I would be looking for a buy on a 06. There appears there is going to be a whole bunch of new epa things added to the 07. Therefor making the performance thing more difficult.

I've been reading a lot of these threads and a lot of bashing about foreign products. I've owned a lot of Hondas and still own Toyotas and they have never let me down in any way. The simple fact is engineering. You ever took apart a Honda or Toyota? All grade 8 bolts and nuts. Ever take apart a Ferd? Grab all the standard and metric sockets and have fun. I know I will hear all the American built this and that but look where our trucks are being built, in Mexico. Look at the Mitsubishi full size box trucks. Automatic trans in them, the fed ex driver owns one, no problems 100k plus miles on trans, gets beat on everyday loaded. Aisin has been building transmissions for some time for foreign cars and trucks. This trans might be the greatest thing since sliced bread. One thing I will say is it will probably be hard to modify and parts will be expensive to buy. But the thing is don’t bash something if you don’t know.

first things first. the 3500 chassis cab will be getting the aisin warner 6spd, not all 3500's. the 68rfe is going into production in Oct and ramps up really quick for begining of 07. this trans is american assembled and will be in the 2500-3500 trucks(not chassis cabs). I am told from one of the engineers that it was and is being tested around 1000 foot lbs. remember they do not shift production to low wage countrys for quality, they do it for profit. if they truely wanted the consumer to benefit they would lower their prices to reflect the savings. remember you said our dodge trucks were built in mexico you meant assembled. where is the parts content manufactured? the early 07's will not have to be compiant only trucks built after jan 1. thus you will have 07.5 just as the 98.5 went to 24 v and the 04.5 added the cat.

Asian-Warner AW-4 tranny's are running around in hundreds of thousands 4.0 Wranglers and Cherokees. When I was a tech at the local Jeep dealer we had no problems whatsoever out of this tranny. If the new 6-spd. auto in the '07 trucks is half as good as the AW-4, it will be a great tranny. Just my $.02

Just a FWIW, my '95 had a cat, '98 didn't, '01.5 had one and my '03 didn't. Just depended on what year met which emissions requirements with or without it.

The transmission actually has six forward ratios but upshifts like a 5spd. 3rd is direct and 4th (.75 O/D) and 5th (.67 O/D) is what the Cummins needs and is what's missing in the 48RE. The jump from direct to .69 O/D is too wide and the two O/D ratio in the 5-45RFE fills the gap. So if this is what's coming and it's as stout as the 48RE, you won't be dissapointed.
