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

This is based on the 1999-2007 GM LS applications available in both 2wd or 4×4.

Built to handle serious horsepower and torque, our LS performance transmissions deliver smooth, reliable shifts and maximum durability. From upgraded stock units to fully race-prepped options, we’ve got the strength and performance your build demands.
