  • Material: Aluminum

The OE plastic front lube/drainback valve assembly can melt at elevated fluid temperature. Once the plastic ball seat or ball seat stop melts it can restrict the front lube oil feed circuit, resulting in overdrive planetary failure. Sonnax offers an improved front lube/drainback valve assembly 36425-01K.

  • Ball seat and stop are manufactured from high-quality aluminum to withstand elevated fluid temperatures and prevent melting.
  • Ensures integrity of the front lube oil feed circuit.
