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."

Good question. When I originally posted this it did not have the thumbs down icon. The posts on this site seem to not be working correctly since some of the recent changes. I do not have a clue how that got in there. I certainly do not feel that way about the new tranny???

 

Just a bit of background. The 6 speed Aisin Warner to be used by Dodge is the same unit that is now used by Hino and Mitsubishi in their medium duty trucks after they experienced all the warranty problems on the World Transmission built by the folks that make the unit for GM. They are designed for up to 4 tons of payload on a Hino, so should be more than adequate for the Dodge.

The Aisin will be the transmission of choice in the new Toyota diesel.

If you own a Volvo prior to Ford's screwing them up, any Japanese car or pickup with an automatic you have an Aisin. You will also remember that they require little to no service, never fail, and have few shops around that work on them because they do not break.

Aisin-Warner is what happened to the old line US Borg-Warner company that built automatics for the US market prior to the disposable transmissions of the 70's and newer US automobiles. For the most part they are bullet proof.

There are some considerations with the new Dodge to deal with, but those are really in your favor in the long haul. The Dodge application will be the first fully integrated shift and fueling management system on a US small truck. This is the same technology used by the larger HD trucks that cuts the fuel (power) during shifts, and that extends the life of the transmission and drivetrain many times.

Frankly, I would be much more worried about the 6.7 Cummins, and the afterburner particulate filter that requires an additional open valve fuel charge to keep it lit, than I ever would about the Aisin transmission.

 

Actually the Allison-Dmax combo would be the first to do that. They have the de-fuel and up-fuel shifting integrated into the ECM. That feature can be disabled with Edge or other type fuel boxes, but can grenade the Allison pretty quickly.. But that has been out since 01..

FWIW..

 

sorry to say that ford has had the defueling/shifting feature since 03..................and it sucks!!!!!!!!!!!!!!!
