Description

Features and Benefits:

  • PTFE Impregnated Rear Stator Support Bushing
  • Modified Input Housing
  • Input Drum Reinforcement Sleeve
  • Overrun Piston Inner Seal
  • Overrun Piston
  • 3-4 Clutch Apply Plate
  • 3-4 Clutch Return Springs (10)
  • Bolt-on Anchor Plate
  • Overrun Piston Outer Seal
  • Socket Head Cap Screws (15)
  • Physically larger clutch pack area for increased 3-4 clutch capacity without sacrificing clutch durability. Use your choice of:
    • Modified Input Housing
    • (8) .067” frictions with (7) .095” steels
    • (9) .062” frictions with (8) .077” steels
  • Anchored backing plate keeps clutches parallel to stop the flexing and distortion that leads to heat build-up
  • Treated housing is significantly more resistant to fatigue failure
  • Steel reinforcement sleeve prevents breakage in the spline area
  • Custom backing plate replaces OE retaining ring to eliminate risk of blowout

Limitations of the GM 4L60-E, 4L65-E, 4L70-E OE input housing are the root cause of 3-4 burn-up in performance applications. The weak OE backing plate flexes during clutch apply, allowing heat to build up unevenly within the clutch pack’s limited space. 

Sonnax Smart-Tech Input Housing Kit 77733-06K makes room for a taller clutch pack, anchored in place by a stronger backing plate, making it the only way to increase clutch capacity and protect against destructive heat. 

Numerous other improvements to the housing ensure maximum durability and protection against failure in higher-horsepower, higher-pressure applications. 

The housing also is available with a pre-installed heavy-duty input shaft (77733-12K).
