Sonnax highlights its oversized cooler/lube flow control valve kit for Toyota UA/AB transmissions. Sonnax says users can recover hydraulic control and restore cooler/lube performance in Toyota/Lexus UA80E, UA80F, UB80E, UB80F transmissions by reconditioning the bore and installing this kit (part no. 168740-08K).
According to Sonnax, the kit features an extended outboard spool that is 164% longer than OE, greater sealing and valve stability.
