just got an installed the 45rfe line pressure booster from sonnax
really made the shifts on our jeep a lot better. i was on the fence, it is 50$ but seems well worth it to me. cleaned up the shifts, and it downshifts better on the highway too. everything is better so far.
just thought i would share with everyone. will post any other results i find.

Hmmm. I stumbled upon that a while back but thought it was too simple. Mine shifts sort of soft but I am used to Fords. Might have to give it a try. Are there any bad things that can happen?

Without being able to adjust line pressure through programming (like in the 04+ Rams), an inline resistor is what is needed. I have one of these on my 03 hemi.
