The Ford 6R140 transmission varies line pressure between 70 and 170 psi. This works well for stock trucks but for heavy duty use and higher horsepower applications this may be insufficient. BD's PressureLoc for the 6R140 is a solenoid replacement that overrides the transmission line pressure to maximize output enabling the transmission to handle higher horsepower. The BD PressureLoc will allow the transmission to produce 250-300psi, substantially increasing clutch holding power which prevents clutch slippage and premature clutch failure. FEATURES Will not conflict with existing transmission tuning. Delivers up to 320 PSI of apply pressure 79% increase in holding power Prevents clutch slippage Prevents shift flare Increased durability due to higher clutch holding capacity Fast and simple installation No tuning required WARRANTY Parts 12-Months 24,000 Miles VIDEOS 6R140 Accessories!
