Line Pressure Booster (Diesel) for Chrysler 68RFE

c/w: 1 green wire and 2 black wires

The 68RFE uses a full-range line pressure sensor mounted on the outside of the transmission for closed loop line control. Traditional methods of raising line pressure by changing the PR spring or valves have no effect. This line pressure booster for Chrysler 68RFE transmissions alters the pressure signal sent to the computer, causing the computer to raise line pressure. This model (#44957-LB1) provides 10-15 psi increase.

Higher line pressure increases clutch holding power and torque capacity but with this transmission, the increase has a limited effect on shift feel. Changes in shift feel will be noticed mostly under aggressive driving or loaded conditions. This part is ideal for heavy duty and modified vehicles and even stock transmissions when a little extra pressure is desired. No other modifications are required.

The line pressure booster installs between the pressure sensor and vehicle harness using OEM-style sealed connectors.
