#45LPB / #68LPB. This family of transmissions uses a full range line pressure sensor mounted on the outside of the transmission for "closed loop" line pressure control. Due to this system, traditional methods of raising line pressure by changing the PR spring or valves have no effect. This Line Pressure Booster alters the pressure signal sent to the computer causing the computer to raise line pressure. The 68RFE has a 10-15 PSI increase and the 45RFE and 545RFE has a 15-30 PSI increase. Higher line pressure increases clutch holding power and torque capacity. 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. Simply unplug the vehicle harness and reconnect with one of these parts. Cost $49.00


Has anybody done this mod? Would this help the transmission?

 

its the same thing as a powerwire, but for your transmission basically. when you buy a shift kit from transgo, they send you a little resistor along with it too. it does the same thing as the product you are talking about. some people install it, some dont. some claims better shifting, others say it doesnt do anything. also keep in mind, that some tuners also boost line pressure. and you dont want to end up going to much.
