BD's Tugger kit doubles low clutch holding pressure in manual 1 for downhill use and high-speed pull-in to 1, and it is built to handle an exhaust brake.
It also adjusts shift firmness, adds cooling and lubrication, and improves converter feed and capacity. The internal parts require removing the transmission, and BD recommends an experienced technician.
