Good Idea to start its own Thread Timmy
it was kind of a thread hijack on the broken transmission thread


It's about the fastest easiest performance mod you can add for $50
although its little more than a resistor housed in a stock connector, it does the job.

I'm not sure it will show up on a timeslip as a huge benefit,
but just the increased firmness of the shifts makes it great for daily driving.

The biggest benefit for those that race, or just drive hard, is extending the life of your transmission because it increases the holding power of the internal clutch packs.

Less clutch slip = less chance of burning the frictions off the clutch plates = less change of a burnt up transmission.



45RFE - 545RFE - 68RFE Line Pressure Booster
#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

Increased line pressure
Increased clutch clamping force and torque capacity
Installs on outside of transmission
Easy plug and play installation




You can pick one up at several places on line
