When I look it up the options it gives are 1. (Passenger side) from cooler 4 spd 2. Transmission to radiator (upper) 4spd 3.4 spd trans pressure line 4. 4spd trans return line 5. 5spd tans pressure line

If you knew which it is i'll share the part number

I was able to find an entire parts manual and service manual for the 2nd gen, in online archives. The 2004 part number(s) for a 4.7L 545rfe 4x4 appear as follows:

Pressure line: 55056420AA Return line: 55056422AA

I found the 2006 parts book as well. The drawing and layout are identical, the parts look the same, but for whatever reason they excluded the pressure line part numbers for both transmissions.

The return line for the 545rfe is: 52029226AD

This is the best I've got short of just googling "2006 dodge dakota transmission cooler lines 545rfe".
