Luk TC0011 Automatic Transmission Torque Converter

LuK TC0011 Torque Converter for 68RFE Diesel

LuK TC0011 is a new automatic transmission torque converter built for the diesel version of the 68RFE. It replaces the OE-style unit with a quad-plate lock-up clutch, giving this Ram 2500 and Ram 3500 application a higher torque-capacity design while keeping a similar overall size profile.

Key Features

• Automatic transmission torque converter for the diesel 68RFE
• Quad-plate lock-up clutch for increased torque capacity
• New components throughout for consistent build quality
• LuK friction material and INA thrust bearings
• Fully furnace-brazed fins for added durability
• 27-spline design with 13.110 in. outside diameter
• Direct replacement profile for selected Ram and Dodge Ram diesel applications

Detailed Description

TC0011 is engineered as a standard replacement torque converter for diesel 68RFE transmissions, with dimensions that closely follow the original fitment profile. It uses a quad-plate lock-up clutch instead of the OE dual-plate setup, which increases torque handling for demanding diesel use. The converter also uses LuK friction material, INA thrust bearings, and furnace-brazed fins to support smooth operation and long-term durability. This part cross-references 4840011770 for the same application.

What It Helps Address

• Lock-up clutch slip under diesel torque loads
• Harsh or inconsistent converter engagement
• Wear related to remanufactured converter cores
• Reduced durability in heavy-duty Ram 2500 and Ram 3500 service
• Fitment concerns when replacing a worn 68RFE torque converter

Installation Notes and Fitment

Fits 2011-2023 Ram 2500, N/A. Fits 2011-2023 Ram 3500, N/A. Fits 2009-2010 Dodge Ram 2500, N/A. Fits 2007-2010 Dodge Ram 3500, N/A. Mounting bolts for 6-M10 x 1.5 applications are noted in the fitment data. Verify transmission type, spline count, pilot dimensions, and mounting pad measurements before installation. Part number TC0011 is designed for the diesel version of the 68RFE and should be matched to the vehicle’s transmission configuration.

Quality Assurance

LuK builds TC0011 with all-new components rather than a remanufactured core, helping reduce the risk of issues tied to reused converter parts. The furnace-brazed fin construction, LuK friction material, and INA thrust bearings reflect a focus on consistent operation and durability in diesel Ram 2500 and Ram 3500 applications.
