I'm considering the Sonnax transmission line pressure gizmo. Does anyone know what the resistor value is on the one for the 68rfe? I googled "68rfe line pressure" and found a link to the Dodge forum and there is a DIY instruction on there for the smaller version of our trannys which just adds a resistor between the two wires that are on the two pins that are directly vertical of each other which is all that the Sonnax one is. On these smaller trannies, the increase is about 30 psi, where as ours are only about 15 psi. I'm cheap and would gladly spend only $3 on a resistor and do the job my self but the resistor will be different than the one they use.
