Luk TC0017 Automatic Transmission Torque Converter

LuK TC0017 Torque Converter Overview

The LuK TC0017 automatic transmission torque converter is built for 6L80 applications that need a direct replacement with updated internal design. It serves a wide range of Chevrolet Silverado 1500, GMC Sierra 1500, Tahoe, Yukon, and related GM trucks and SUVs from 2007-2022.

Designed around the 6L80 transmission, this torque converter uses a dual-plate lockup design and a revised mounting plate to improve clutch apply stability and torque handling. The TC0017 is engineered to replace multiple OE part numbers with one service part.

Detailed Description

LuK TC0017 is a 6L80 torque converter for GM rear-wheel-drive and truck/SUV applications, including Chevrolet Silverado 1500, GMC Sierra 1500, Chevrolet Tahoe, GMC Yukon, and Cadillac Escalade platforms. It also covers select Chevrolet Express, GMC Savana, Camaro, Caprice, SS, Avalanche, Suburban, and Yukon XL applications listed for the 6L80 transmission. The dual-plate lockup setup replaces the OE single-plate style and uses Schaeffler friction material for consistent clutch engagement. A revised mounting plate helps reduce cover warping and flexing at the clutch apply surface, supporting longer service life than rebuilt converters in demanding use.

This part cross-references 4840017770 for the same application.

Common Problems This Part Can Address

• Torque converter clutch shudder or inconsistent lockup operation
• Excessive wear in a high-mileage 6L80 transmission
• Converter cover flexing or warping at the clutch apply surface
• Reduced torque transfer under load in truck and SUV service
• Need for a single replacement part across multiple OE SKUs
