Description

The Diamond T FT99GSD torque converter is a high-performance upgrade specifically engineered for 1999-2003 Ford F-250 and F-350 models equipped with the 5.4L gas engine and the 4R100 transmission. This triple-disk converter features a robust 4-stud billet cover and a heavy-duty design, aimed at improving acceleration, pulling power, and overall vehicle efficiency. Diamond T Enterprises emphasizes quality and durability in their torque converters. Each unit is built in the USA using the highest grade components. Unlike mass-produced remanufactured converters, Diamond T technicians maintain the original parts together as a matched set to ensure superior quality. They meticulously inspect all parts, replacing any marginal ones, and verify housing thickness against OEM specifications, replacing thin housings with new ones to prevent premature failure. The converters are precision balanced using computerized equipment and utilize only the best clutch materials. To prevent internal rust before installation, they are pre-charged with transmission fluid, and each unit undergoes quality testing before shipment. This torque converter is backed by a Lifetime Non-Transferable Warranty against defects in material and workmanship under normal and proper use. However, the warranty is void if the product experiences improper installation, accidents, neglect, misuse, or dismantling/alteration by the customer or a third party. A core charge applies to this purchase, and the customer is responsible for the return shipping costs of the core.
