ZF6 / ZF8 Transmission Oil Thermostat

Compact high-flow transmission oil thermostat from Improved Racing, used by KINGPIN Fab in our ZF automatic M57 conversions.

A transmission cooler is useful, but over-cooling the oil is not. This thermostat bypasses the external cooler while the fluid is cold, helping the transmission reach operating temperature more quickly, then progressively directs flow through the cooler as temperature rises.

Specifications

  • Suitable for ZF6HP and ZF8HP transmission cooling systems
  • Opens at approximately 74°C / 165°F
  • Fully open at approximately 83°C / 181°F
  • Female -6AN O-ring boss ports
  • Maximum stated flow: 5 GPM / 18.93 LPM

Fitting options

  • 1/2-inch barb option for suitable AN8 hose
  • AN8 male option for AN8 female hose ends

Includes

  • 1 x compact remote thermostat block
  • 2 x zinc-plated mounting brackets with screws

Not suitable as an external engine-oil thermostat. Contact us if you need the higher-flow engine-oil version.
