BD Diesel Transmission w/ Pressure Controller - 2011-2016 Chevy LML Allison 4wd

The increased steel mass in this transmission's components helps with better heat dissipation, a notable improvement for heavy-duty applications. This BD Diesel transmission is designed to significantly increase the durability of your drivetrain, especially when your stock transmission is pushed beyond its original limits. It comes with a BD Aluminum HD deep transmission pan that adds an extra 3.5 quarts of oil capacity, keeping things cooler and more lubricated under load.

Included with this transmission is the BD Allison Pressure Box, which can deliver up to 275 PSI of line pressure. This, combined with an increased clutch count across multiple clutch packs – C1 sees an 8-clutch setup (14% over stock), C2, C4, and C5 have 7 clutches each (17% over stock), and C3 gets a substantial 7-clutch setup (75% over stock) – means the transmission can handle more power and torque reliably. It also features high-energy GPZ frictions for improved performance and longevity.

Each transmission is dyno tested to ensure it meets performance standards before it leaves the shop. This unit is a Stage 4 build, featuring a billet input shaft and triple torque converter, making it a solid option for those looking to enhance their truck's towing and hauling capabilities. It's a complete assembly ready to be installed.
