BD Diesel Tugger Shift Kit - 1999-2003 Ford 4R100

This BD Diesel Tugger Shift Kit is designed for the 4R100 automatic transmission found in 1999-2003 Ford F-250 and F-350 Super Duty trucks. It's built to handle the demands of working trucks, especially when towing or using an exhaust brake. The kit specifically doubles the low clutch holding pressure in first gear, which is a big help for downhill use and allows for a higher speed pull into first gear. This updated design also adjusts shift firmness for a more solid feel and provides better converter feed and capacity, leading to improved cooling and lubrication for your transmission.

Installing this kit involves internal transmission work, so it requires removing the transmission from the vehicle. Because of this, we recommend installation by an experienced technician. The goal here is to get more consistent performance and better longevity out of your transmission, especially under heavy load. You can expect improved cooling and lubrication, which helps reduce heat buildup and wear.

BD Diesel has been a well-known name in diesel performance since 1989, focusing on components that improve the function and durability of diesel powertrains. This shift kit comes with a 12-month or 12,000-mile warranty to back up its construction.
