Each 4L80 Transmission Includes :

• 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.
• Complete road simulation testing using USEP’s proprietary dynamometer testing program called CARS (Computer-Aided Road Simulation). Every transmission is cold- and hot-tested while using Synthetic ATF, a custom-blended fully
synthetic automatic transmission fluid, and filtration system.
