This isn't your average rebuild — we break down what makes a Monster 6L80E different from stock, including key upgrades inside the transmission case.
We show off our billet 4-5-6 hub, improved clutches, and custom valve body mods to increase line pressure and holding capacity — especially in high-torque applications.
Matched with a Thor torque converter, our 6L80E combo delivers enhanced stall speed, improved lock-up control, and better heat resistance for towing and performance builds.
Whether it's daily driving, boosted power, or weekend drag racing, we tailor the build for your needs — including converter pairing, shift programming, and dyno verification.
