Aisin AW 450-43LE transmissions may exhibit multiple shift problems due to excessive wear in the solenoid modulator circuit. Loss of 3rd, 4th gear and no TCC apply are common, along with low line pressure and flare shifts. Bore wear at the inboard end results in high solenoid pressure, improper gear or harsh shifts. Oversized Sonnax solenoid modulator valve kit 94987-14K allows the bore to be renewed, restoring hydraulic integrity for a properly modulated solenoid pressure.

Valve is hardcoat anodized to reduce wear
Valve has added length at the outboard spool for additional support
