It is the Lexus RX450h Shift Solenoid which provides the hybrid SUV with rapid, smooth gear shifts by pushing pressurized transmission fluid precisely when the control computer requires the vehicle to switch ratio. Within the automatic gearbox, the Lexus Shift Solenoid contains a smart coil and iron plunger to snap open or closed in milliseconds, providing hydraulic force to the right clutch pack, whether to make butter smooth upshifts or decisive downshifts. Since the Shift Solenoid reacts to throttle angle, speed, and fluid temperature in real time, it assists the RX450h to maintain low engine revs when cruising to maximize efficiency and avoid subjecting internal components to brutal shocks. The owners compliment how this Lexus piece works with the electric motors to remove the gear hunting that is occasionally experienced in other hybrids, highlighting its status of being exceptionally durable during the various years of production of the RX450h. The identical Shift Solenoid design fits 2010 through current RX450h models in front wheel drive and all wheel drive models, and thus drivers will have the same performance as software upgrades optimize the entire drive system. Constructed to factory specifications, the Lexus Shift Solenoid is heat resistant, varnish resistant, and fluid shear resistant to increase the life of the transmission and aid the already popular Lexus safety record by preventing unexpected neutral drops. With the Shift Solenoid directing pressure to the torque converter clutch, the hybrid coasts more efficiently, consumption of fuel is reduced, emissions are minimized without the loss of acceleration confidence that makes the RX450h a favorite in the city. Its silent mechanism is a complement to the insulated cabin, which enables the Lexus passengers to experience the peaceful ride as the unit silently makes thousands of shifts each time there is a road trip. Simply put, the RX450h has a designed Shift Solenoid that is designed to last long, actuate quickly, and fit perfectly, the petite yet significant component that makes Lexus hybrid drives appear out of the crowd.
