Chuck, the 45RFE is the same transmission that is used in 4.7L powered
Dakotas and Durangos. It is an automatic overdrive that has 5 forward gears,
one of them being a "2nd over". Basically it has 2 different 2nd gear
ratios- one for accelerating(lower for better acceleration) and one for
kick-down or passing(higher so as not to make the RPM's jump as high when it
is kicked down). The 46RE is the same old A727-based 4-speed overdrive that
was also called the A518 and 46RH. It is the same transmission that is used
in the Dakota R/T and the 360 powered quad cabs and Durangos.The 45RFE is
pretty highly revered and has a descent approval rating right now. There has
been a few cases of them jumping to another valve body postion without
warning, but it is not a common problem. The 46RE's are just as they have
been-lazy shifts, lack of refinement,etc. It's based on a design that's
almost 40 years old! Need to know the ratios or anything else??

Sorry for the off topic post, but what is the difference between the 46RE
and 45RFE automatic transmissions for the new Ram's? Has anyone heard of any
problems with either?

again!! The down time is being well spent though ;-)
