does the 2500 series ram power wagon with the hemi use the same transmission as the 1500 series or is the 2500 series a heavier duty trans?

 

same 545RFE

 

If you have a 5 speed in a Ram 1500, 2500, or 3500 built after 2001 it is a 545RFE, and if you have a 5.7 in your Power Wagon its got a 5 speed. The 6 speed auto offered with the Cummings is a 68RFE, that thing is a beast and probably a bit of overkill for a 5.7, which for most of us would not be a problem

 

The only engine you can get with the Power Wagon is the 5.7L (345 c.i.) HEMI. The 545RFE transmission, the same as 1500, 2500, and 3500 models, is the only transmission available in the Power Wagon for the 2005 and 2010-present models. The 2006-2009 models were available, I wish my 2005 had one, with the G-56 6-speed manual transmission. A very rare beast.
