TransGo's Fully CNC'd Overdrive Pressure Plate


Transtar Part #:  T72140HD

Hot-forged 1045 steel fully CNC'd overdrive pressure plate allows the addition of extra capacity to the OD stack in all models.

Corrects, Prevents, Reduces

  • Friction failure when combined with aftermarket engine performance add-ons
  • Soft, slipping or erratic shifting
  • Over pressurization/ ballooning of the torque converter
  • Harsh triple-disc converter apply



  • The new RFE high-pressure kits allow increased engine horsepower and torque via aftermarket tuners and other mods without the driveability side effects and costs associated with external transmission PCM programming. Included with the many performance and tow upgrades is an optional triple-disc converter calibration valve, for use with triple-disc converters to modulate the apply rate of the converter clutch, preventing harsh lockup engagement complaints without diminishing increased holding power benefits.

  • For even greater overdrive clutch capacity, TransGo offers an optional hot-forged 1045 steel fully CNC'd overdrive pressure plate (part #T-72140HD sold separately) allowing the addition of extra capacity to the OD stack in all models.
