Description
4L80E Transmission and Torque Converter
Our 4L80E features so many performance enhancing upgrades, you could accuse me of being on steroids. We've updated the case connected to the latest design on all models and versions prior to 1994. The vehicle harness pigtail is provided to address connection issues that plagued some of the earlier 4L80E's. We implement a fully remanufactured valve body with complete system correction and recalibration, this improves pressure control and quality of shifting.
This 4L80E transmission has an upgraded 43 element intermediate sprag that will increase holding capacity. The EPC solenoid is tested separate from the transmission to confirm precise pressure control. We have updated the force motor to comply with the need for improved pressure control. An updated pressure regulator prevents dangerously high pressure. Our reinforced 4L80E torque converter muses furnace brazing to maximize torque and efficiency.
