DESCRIPTION
4L80e Street Spec Performance Transmission Capable or 750 HP
We start with a fresh never rebuilt 4L80E core with zero case damage for all performance builds. The units are torn down and put through our rigorous inspection process to confirm the quality of the core meets the stringent guideline you would expect from a performance transmission. Every unit receives a complete rebuild regardless of the condition of internal parts.
Once fully assembled the unit is dyno tested using our proprietary programming on one of our Axiline dyno machines to confirm proper operation prior to packaging and shipping to you. This unit is perfect to pair with one of our 370 or 408 Boost Ready Engine Applications
