SPE Spec 6R140- Fits 11-19 F250/F350/F450




The 6R140 Torqshift transmission can be a very stable and reliable transmission if built correctly. Here are some of the improvements we make on all of our Torqshift transmissions: 

Base Unit Spec 800hp :

  • SPE Modified high volume front pump assembly

  • SPE completely custom solenoid body 

  • SPE added count clutch packs proprietary friction to direct & overdrive

  • New Torrington thrust bearings

  • New thrust washers

  • New bushings

  • Enhanced solenoids

  • SPE shift enhancement

  • Deep Pan

  • Modified E clutch Control circuit

  • SPE patented thermoreg valve assembly (drops trans temps by 50deg)


SPE Comp Transmission Spec 1200hp+ :
Includes everything above along with these additional items:
  • SPE completely custom solenoid body (No cores components used this is an SPE part)
  • Cryo treated shafts & planetaries 
  • SPE comp clutches and added counts for all clutch packs
  • All clearances blueprinted and documented
SPE Modifies The 3-4 E clutch control circuit. This eliminates the 3-4 squawk without changing any internal hard parts like other companies. There are ways to do it mechanically but it adds complication and added components to fail. 

***SPE will only charge you exact shipping. If shipping is less than the $700, SPE will refund you accordingly. If shipping is greater than $700, SPE will contact you for the difference
