The Transmission Authority is the authority on quality, selection, and convenience. All of The Transmission Authority's remanufactured transmissions follow strict build specifications and undergo a variety of testing throughout the manufacturing process, including proprietary dynamometer testing for at least 30 minutes. When you need a remanufactured transmission that is powerful, efficient, reliable, and covered by the industry's best warranty, look no further.

Features:

  • Fully remanufactured valve body, with complete system correction and recalibration kit, improves pressure control and shift quality
  • Upgraded actuator feed limit valve prevents missing shifts and premature transmission failure
  • Upgraded 34 element intermediate sprag increases holding capacity
  • All-new shift solenoids ensure positive shifting
  • EPC solenoid is tested separate from the transmission to confirm precise pressure control
  • Updated force motor for improved pressure control
  • Updated pressure regulator prevents overly high pressure
  • Case connector is updated to the latest design on pre-1994 versions, and a vehicle harness pigtail is provided to address connection issues with the early design
  • Fully remanufactured torque converter is tested for leaks, lock-up, concentricity, and balance. Upgrades exceed OE requirements and eliminate the possibilities of front seal leaks, premature bushing wear, and vibration
  • No Walkout rear case bushing is installed, addressing an OE flaw, to prevent case and output shaft damage
  • All-new custom-spec bushings to improve internal fluid flow control and pressures
  • Every transmission is cold-and hot-tested using a proprietary dynamometer testing program that includes fully synthetic automatic transmission fluid and a filtration system
