68RFE is the 6 speed automatic transmission that comes in the pickup 6.7's. If you have a 6.7, with a pickup bed and an automatic, you have a 68RFE.

Huh... I learned something new. I thought the RFE meant Real F'ing Expensive. Cause it seemed quite expensive if you screw it up.

Being a 4x4 has nothing to do with it if its automatic its a 68rfe if you have a manual you have what is called a G56 which is a mercedes benz design 6 speed manual

If I'm not mistaken, I think that 68RFE stands for: 6 speeds, 800 trq capable from the factory, Rear wheel drive, Front Engine....

the 6 is 6 speed, the 8 is the duty number, lower number, lower duty, The R stands for Rear Wheel Drive, The E stands for Electronic Controlled. The F I don't know about.

Ok, the F stands for Fully Electronic as in a TCM

I see your point, I was assuming he had an automatic.
