Remanufactured 6L80 Transmissions That Just Work

If you’ve been dealing with 6L80 failures, you already know the signs: torque converter shudder, harsh 2-3 shifts, or random no-drive scenarios. These aren’t isolated issues — they’re part of the 6L80’s DNA.

At ACE, we don’t just repair 6L80s — we remanufacture them with critical updates and real-world testing that helps your shop avoid comebacks and costly downtime. Our builds are engineered for Silverado fleets, Tahoe owners, and every GM customer who counts on performance.
