Diamond T is by far our most popular line on Torque Converters and we even run them in our personal vehicles. The quality is top notch and certainly an upgrade of the stock units.
Quality and reliablility Diamond T Torque Converter for GM (2017-19) 6.6L Duramax w/Allison 550hp Dual Disk
How is the quality of this? Over OEM one. Mine is making a noice when it goes into lockup mode. Shifting from 2nd to 3rd gear. My truck is tuned. But nothing crazy. Don’t romp on it. Just looking for something for normal driving and some towing that will hold up and not fail in a few years. Thanks
