 Product Description

Ford 6R60/6R75/6R80 Transmission Sure-Cool Thermal Control Bypass Valve

Made in the USA by Superior Transmission Parts

  • Full time cooler flow with much lower average fluid temperature
  • Built in high pressure safety bypass into the lube circuit
  • Immediate and accurate fluid level check without warm-up cycle, which saves tech time for re-racking and rechecking
  • Fits all 6R60 Explorer, 6R75 Expedition/Navigator, and 6R80 Mustangs/F-150

The OEM wax pellet style thermostatic flow control system defaults to cooler flow OFF state.  It requires a preheat cycle up to the boiling temperature of water or higher to switch to cooler flow ON state.  When it malfunctions (typically in the OFF state), cooler flow is bypassed and the ATF and transmission are overheated.  This affects pump, valve body and solenoids as well as sealing rings and clutch drums operation.

The patented Sure-Cool systems default to cooler flow ON state, which provides instant fill and air purge of cooler and lines so that accurate fluid level can be established during initial star up after repair without lengthy warm up cycle.  Installers do not need to handle a hot transmission.  The default ON state will typically maintain stable ATF operating temperature around 160 degrees even under working conditions.  This extends fluid life, prevents a wide range of over-temp operating malfunctions, and helps the controls system provide consistent shift and operation control.  When the OEM thermostatic system is switched to cooler flow ON state, if the radiator gets blocked or cooler lines get pinched, all lube flow is blocked with results in a cascade failure to flow (needle bearings, bushings and crashed planetaries).  With the Sure-Cool system installed, if cooler flow gets blocked, it immediately bypasses directly into the lube circuits to maintain lube flow to the planets avoiding total failure.

  1. nice product

    Posted by Unknown on Aug 24th 2019

    I try this product and it’s really nice before my trans temp reached 117c when i’m driving so fast and now maximum temp i’ve saw 100c

  2. Great product

    Works better than described!
    lowered trans temp 40+ degrees!
    Must have for any towing or for every day use,
    2.7 ecoboost runs 130 to 140 on a hot day. It ran 200 + before.
    G.M. transmission also run hot. Basically the same trans.
    Global has the answer for them too!

  3. won't get over 170!!!

    Easy install with basic hand tools. My trans temps went from 205 while pulling 6k lbs with my 11 f150 5.0 to 170 and generally runs 130 to 150 when just driving around town not sure why ford wanted to dang near boil the fluid my guess is to shorten the trans life! Worth every penny.
