BD Diesel Transmission - 2004.5-2006 Chev LLY Allison 1000 5-speed 2wd 1064722

The stock transmission and torque converter were designed to handle the output of the stock engine, but not much more. Increase the durability of your drivetrain with a BD transmission and torque converter. BD's transmissions incorporate revised oil circuits, extra clutches and stronger internals to handle more power and torque than the stock transmission. All transmissions come with BD's heavy duty transmission pan for added protection and cooling! By design, OEM transmission Helical gears and engine torque thrusting causes stock plastic and Babbitt thrust washers to melt and break down contaminating lubrication oil and damaging solenoids. We remove the thrust washers and install roller bearings throughout the transmission which eliminates oil contamination, maintains tolerances, reduces heat and prevents premature solenoid failure.
