Does anyone know who makes the 6 speed automatic tranny in the 2009 3500 w/Cummins?

 

I believe that the 6 speed is Chrysler's own design. From pretty much all accounts, it's been a smash hit right out of the box from the time it was introduced in the 07 model year. The 6 speed manual is manufactured by Aisin.

 

I guess I had it backwards then, because I owned an '08 and I thought the 6-speed auto was made by Aisin. I liked the auto tranny and the engine brake, but hated the check engine lights.

 

I thought the 68RFE was Mopar and the AS68RFE in the Cab & Chassis trucks was Aisin. (both auto's). Hopefully someone will step in and say for sure, I've heard just about every variation lol

 

if you have a 2500 or 3500(non Cab&Chassis) and it has an automatic transmission, it is a 68RFE and is an in-house transmission.

if you have a 3500, 4500 or 5500 Cab&Chassis and it has an automatic transmission, it is an AS68RC and is sourced from Aisin.

the manual transmission is the G56 and is a carryover from previous generations

 

What he said is correct, both automatic transmissions are very good. I have an 07 C&C that now has over 220,000 miles on it pulling a heavy 40' gooseneck with no problems at all. I know several people that hotshot with the pickup model and they have had no problems with the pickup transmission either.

 

The manual G56 is made by Getrag.

 

I take the g56 mercedes makes is really a car transmission with the same name.

 

68RFE made Orion industries, a Chrysler subsidiary.

AS68Rc is made by Aisin, (as previously stated). Aisin make all Toyota automatic trannies.

Aisin is the Jap answer to Allison.

 

The manual g56 is made by my Great Aunt Mildred in her basement in Fond du Lac, WI.
