Twisted Street™ 6L80E Performance Transmission | High-Energy Clutches & Steels + Super Duty Billet Cover Torque Converter
Stronger Than Stock. Daily Driver Ready. Built the Twisted Torque™ Way.
The Twisted Street™ 6L80E is our entry-level performance transmission for GM cars, trucks, and SUVs that need more than a factory-style replacement without sacrificing everyday drivability.
Every transmission is completely torn down, cleaned, inspected, and rebuilt in-house with high-energy performance clutches, new matched steels, corrected hydraulics, and a NEW pump and bellhousing assembly.
We finish every build with our Super Duty Billet Cover Torque Converter at factory stall speed — INCLUDED.
Built for stock and mildly modified applications rated up to 450 HP.
