Aisin AW 450-43LE transmissions may exhibit multiple shift problems due to excess 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. Sonnax oversized solenoid modulator valve kit 94987-14K allows the bore to be renewed, restoring hydraulic integrity for a properly modulated solenoid pressure.

Hardcoat anodized aluminum valve combats premature wear
Valve has added length at the outboard spool for additional support
