Product Details

The Sonnax 57917E-03K is designed for Toyota/Lexus U140E, U140F, U151E, U151F, U240E, U241E, and U250E transmissions, where the lockup control plunger valve controls torque converter apply and release functions. Wear at the plunger sleeve location can cause converter apply pressure to exhaust, leading to TCC apply and release problems, trouble codes, and converter failure.

Key Features:

  • Hardcoat anodized aluminum valve construction combats premature wear
  • Annular grooves added to the valve prevent sideloading-related wear
  • Sleeve manufactured from highly wear-resistant billet aluminum
  • Drop-in Zip Valve design installs quickly and easily
  • Complete kit includes both replacement sleeve and plunger valve

This valve kit restores proper hydraulic control at the lockup control plunger location, preventing converter clutch issues and extending transmission life. Ideal for transmission rebuilders addressing TCC concerns or performing preventative maintenance during overhauls.
