Diesel High Torque Towing 4L80E Lock-up Converter for all 6.5TD applications 1992-up.

These TCI High Torque Towing converters are efficient units that put more of your engine's torque to the ground. Slippage is minimized, providing better gas mileage and as much as a 20 degree F reduction in transmission temperature. Another benefit is reduced engine rpm at highway speed.

TCI strives to produce the best torque converters in the industry. Part of the process involves ensuring that each unit is built to spec. Regardless of what category or price level it may fall into, every TCI torque converter is Triple Tested during assembly.

Once all the prep work on the component parts has been completed, the impeller is welded to the front cover. Immediately following this process, a pair of dial indicators are employed on a rotating table to verify that the impeller body and pump drive hub are true.

Each unit is then pressurized and subjected to a leak test to confirm the integrity of all the weld seams. Lastly, each unit is computer balanced to reduce annoying and potentially damaging drivetrain vibrations that would occur from an unbalanced torque converter. That's Triple Tested so you can be confident you're getting a torque converter that's ready to roll.
