EBAY Dodge Sonnax Line Pressure Booster 45RFE 

It works pretty well. Make sure to disconnect the battery so the trans can relearn. I'd say it's very noticeable, more so in higher rpm's.

Turns Out 680Ohms Is About 35PSI Drop In Pressure Sensor Reading. So Actual Line Pressure Is About 35PSI Higher. My Line Pressure Max With Stock Regulator Spring In Pump Is Right At 160. Set Neutral Min Line Pressure In HP Tuners To 160 With Line Pressure Boost And Found My Actual Line Pressure Reading On Scanner Was 125 Where Desired Was 160. So The Booster Was Hitting 160 PSI At 125PSI Scanner Reading. Scaled All My Shift Pressures Down By 35 So Actual And Desired Match More Closely. The Shifting Is Now Way Less Agressive And Not Damaging Feeling. The Holding Line Pressure Is Now 35PSI Higher During WOT Which I'm Stoked About. You Can Change The Shift Pressures To Say 160 On HP Tuners But The Hard Coded Holding Pressure (Line Pressure When You Have Been In A Gear WOT) Is 125 PSI. So When WOT Your Line Pressure Read 160 For The Shift Then It Drops Down To 125 To Hold The Clutches. There's Nothing In HP Tuners You Can Do To Change This. But Now With This Line Booster Holding And Shifting Pressure Are Both 160PSI Now. I Changed My Shift Pressure To 125 (Actualy 160 with line pressure booster) . So Now It's 125 The Entire Time WOT In All Gears (Actually 160PSI). I Have So Much More Reassurance For The This Tranny Behind My 5800Lb Turbo AWD Hemi Jeep!!!

All I did was the harness. It does a little but a shift kit is the best increasing line pressure

That's what I thought too

Correct. It's a cheap knock off. I believe I mentioned that in the video. Did you not watch the entire video? Usually people skip around then make comments that are explained in the video. The word "eBay" should have been an indication of that.

😂 Subbed

Yeah. Good ole ebay
