The BD Diesel 1064464SM TowMaster package pairs a rebuilt 5R110 TorqShift transmission with a matched BD torque converter for 2003-2004 Ford F-250 and F-350 Super Duty 4WD trucks with the 6.0L Powerstroke, or 2WD trucks with the flanged output. The factory 5R110 runs thin clutch packs and plastic valve body plugs, so added power and heavy trailers lead to slipping, heat and burned clutches. This package is built to carry that load.

BD adds clutches to the intermediate, direct and overdrive packs, swaps the plastic valve body pressure plugs for aluminum, reworks the front pump and installs a heavy duty snap ring and pressure regulator valve. The matched converter adds lock-up clutch material and torque multiplying cast aluminum stators, and the pair is dyno tested before it ships with BD's deep aluminum pan. Core required, refundable deposit at checkout.

Key Features & Benefits

• Increased Clutch Count: Intermediate 5 (+67%), direct 6 (+50%) and overdrive 5 (+67%) over stock.
• Valve Body and Pump Upgrades: Aluminum pressure plugs, reworked front pump and an HD pressure regulator valve help prevent runaway pressure.
• Matched Converter: Street and towing converter with cast aluminum stators, a stamp-forged steel cover and up to triple the lock-up clutch material for lower rpm response and less heat.
• Deep Aluminum Pan: BD HD pan adds 6 quarts of fluid capacity, with a larger late-model sump filter.
• Dyno Tested: Every transmission is tested on BD's dyno before it ships.
