Project Old School: Shifting Into Overdrive
The lock-up solenoid was wired off of a fourth pressure switch. When the trans shifts into overdrive, it will automatically engage the torque converter clutch without any external switches required. This is critical because the engine rpm at cruise may be substantially less than the stall speed of the converter, which is a recipe for disaster. By applying a lock-up converter clutch, you eliminate this slippage and heat source--allowing you to have the benefits of a performance-oriented stall speed, plus economy, efficiency, and lower-operating temperature.
