2007 Aisin AS68RC vs 68RE?

[EMD-Run8]

Been seein' a lot of back and forth about the 68RE. Some are saying that it will be used in the regular 2500/3500 gas/CTD trucks. Some are saying that the Aisin is for chassis cabs only. I'm curious, maybe the Aisin will be for CTD's only and the 68RE will be for gassers. Anybody got any scuttle on that idea? Maybe DC finally got it right and will put an auto in their trucks that's built for a Cummins. Let's just hope the Aisin is well-rated to handle the 6. 7's torque huh?

yes the 68re is for 2500-3500 coming in 07(not the early builds the epa compliant trucks for 07). it is a huge trans built for the cummins in mind. the trans plant in kokomo indiana will assemble the unit. the parts (maybe not all, I am not sure) will be from canadian supplier lanimar( I beleive spelling to be correct, and they do have a web site). we are hoping they switch all the trucks over to the unit built in the states. its bad enough they outsoursed the parts. the line is going in as we type.

Do you mean Linamar? If so, I'm gonna have to keep my eyes open since we make a lot of the special tooling for those guys.

 

[EMD-Run8]

OK, so why the Aisin transmission then? Does it have something the 68RE won't?

The same people that biuld the overpriced vacuum pump for the Jacob's E Brake ?

Any ideas on why the two different trannies?

For one thing, the Aisin will be behind the new 6. 7 litre Cummins engine, whereas, the 68-RE will be behind the 5. 9 litre engine.



Some of the stories (rumors) I've read from guys that seem to work in the transmission plants & "know people" that are familiar with the new transmissions, the new 68-RE will probably be a robust piece.



It sounds like the Aisin is already a solid, well built piece.



If & when it goes into the 2500/3500's, I don't know. Haven't heard, yet.



I went to a seminar (May Madness) given by Mr. Dennis Hurst, the TOP man at the Cummins Engine Plant, in Columbus, IN. Questions were asked of him regarding the new engine/trans. combinations. Some of the questions, He couldn't answer because DC wants to keep some information close to the vest. They don't want the competition to know what they have planned. He did say that we should be happy with the results.

Here's an idea. Maybe the 68RE isn't PTO capable but the Aisin is and therefore it's use in the chassis cabs.

 

[bmoeller]

The 47RE doesn't have the PTO cover, but the t-case does.

I work in one of dc's auto trans plants here in Indiana, whom do you know here? and which plant?

 

[jmorse]

Linamar

These are the same fine folks that built Onan engines for Cummins . The engines no longer exist and it is a good thing because once production moved to Canada, quality went down hill ! Hope they do better on the transmission.

Just a note, I ordered a 3500 mc 4x4 with the 6. 7l Cummins, the dealer faxed me the order form on the 19th and under transmission is it is listed as "HD Automatic HDRFE Transmission"

All I can say is it looks like the first year owners may be guinea pigs.

Thats a bit contrary to all the info so far. The 5. 9 is done for production in the Dodge trucks so how would the trans be restricted to the 5. 9? As of Dec 4 you could not order a 5. 9 only the 6. 7?



I think the Aisin is probably slated for the 4500/550 series trucks so they will use it in the lighter CC also as an intro. The Aisin has options for PTO and is behind the detuned engine for longevity in the fleet operations.



If DC has done as good a job with the 68RFE as they did with the 545RFE it should be a good trans. Whether it is beefy enough to take BOMB's without major mods will be the next big question.

 

[DHayden]

I don't think DC would have gone through the trouble of designing and producing the 68RFE to only put it behind a few of the last 5. 9's.

 

[BRayls]

will not bolt up to the 5. 9 anyhow. bellhousing is much larger.

 

[betterthanstock]

My opinion is that the 68 rfe is a slightly simpler transmission than the aisin, but that it will actually be a stronger one, lighter, and cheaper, since it's built by DC (with parts from who knows where, MB of Brazil?)

They probably have union contracts, so they can keep the 48re plant going.



Also, the Aisin will be in commercial trucks, which are subject to less abuse than pickups, due to weight scales, and commercial licenses. Most commercial users are hired drivers, and the owners do not want to "bomb" or overload their trucks. Look at the engine ratings. The power war is on with the pickups, so they are rated higher than the commercial trucks, and are expected to live less. (and have shorter warranties too)

 

[EMD-Run8]

I would imagine that the average chassis cab will see a fair bit more heavy use than the average pickup. I expect that the Aisin will be a real fine piece.

 

[betterthanstock]

No doubt it will be a fine piece. All I am speculating at this point is that the Aisin will slip at a lower torque than the DC transmission. Also, the Aisin will be designed with thicker clutch linings, for more shifting before wearing out, as long as you stick to the factory torque. The DC will have more clutch discs, and maybe higher internal pressure, but thinner linings, so it will wear out faster, but will hold more torque without slipping. The Aisin may have better filtration too, again for longevity, versus brute strength on the DC version.

Just my educated guess, based on the engine ratings on the two trucks, and the expected power race with Ford, GM, and maybe other newcomers.
