2011-2016 Silverado & Sierra 2500 & 3500 Duramax LML Torque Converters

The factory torque converter on your Duramax LML's transmission may be able to handle normal street driving at stock power levels, but if you're ratcheting up the power or towing heavy loads, you're going to need a torque converter with much higher strength. Tier One's selection of performance torque converters for 2011-2016 Silverado & Sierra 2500 & 3500 Duramax LML trucks can handle the strain of aggressive tuning and tough applications so that you don't end up with a pricey tow bill. Each of these converters features durable construction and improved designs that make them resistant to warping, cracking, or burn-up. We carry everything from uprated stock replacement torque converters to billet torque converters with multi-disc designs that can handle extremely high power levels and competition use. If your torque converter has already failed and sent debris through the rest of the system, a simple replacement might not be enough, and you may need to swap the whole unit with one of our 2011-2016 Duramax LML Complete Transmissions. A torque converter working hard under a heavy load generates massive amounts of heat, so keep that heat from cooking your fluid and ruining your new converter with one of our 2011-2016 Duramax LML Transmission Coolers. To get the most out of your new converter, your transmission needs to apply the correct fluid pressure, so ensure your lock-up is firm and reliable by upgrading to one of our 2011-2016 Duramax LML Valve Bodies. While you have the transmission disconnected to install the converter, it's the perfect time to upgrade other maintenance items, so see what else you should swap in our 2011-2016 Duramax LML Transmission Parts.
