I am also interested in what it has as I recently acquired a 04 quad cab 4x4 with a 3.7. If the 4.7 has the same tranny as the Hemi 5.7 has then the 3.7 must also use the same trans as the 5.7 Hemi, right? If that is right I heard they are excellent transmissions.
I believe that the only application of the 545RFE in the Dakota was with the 4.7L V8. The 3rd Gen Dakota used the 42RLE with the 3.7L V6; therefore, if the 42RE was not used, it was likely the 42RLE. I know this site is far less than perfect, but I believe it is correct. http://en.wikipedia.org/wiki/Ultradrive#42RLE

I didn't realize they kept the 42R(L)E for the 3.7. I mean I can see the (5)45RFE taking more power to turn than the 3.7 makes seeing as it's a not-very-efficient slushbox, but at the same time the 42R(L)E is such an old box from the A904 days, I'd expect DCJ to finally have a new version.

While the names are confusingly similar, there is a big difference between the 42RE and the 42RLE. The 42RE as you listed is based off of the A904 torqueflite. The 42RLE is a rear wheel drive application of the 42LE/A606 Ultradrive first introduced in the LH cars (Intrepid, Concorde, LHS, Vision/300M). The 545RFE has a very strange selection of gear ratios, but is a very durable unit from what I hear. All things being equal if it were possible to use the 545RFE with a 3.7L V6 in a Dakota, that is what I would prefer to use as it has the widest gear ratio spread (545RFE: 3.00=1st to .67=5th vs. 42RLE: 2.80=1st to .69=4th).
