Bully Dog
Duramax Shift Enhancer

(Standard and Super Aggressive)



2001-05 Chevy Duramax

Allison 1000, 2000 and 2400 transmissions


These transmission kits increase line pressure in the transmission, which reduces torque converter and transmission clutch slippage and improves shifting. Easy to install using basic hand tools. Bully Dog’s shift enhancers improve shift and line pressure while reducing slipping and lowering heat. The end result is firmer, quicker shifts which vastly improves the driving experience and longevity of the transmission by lowering transmission temperatures.


The Allison Shift Enhancer is the simplest, most effective kit available without having to pull the transmission. It literally gives the clutches more traction in the clutch packs. It allows for a quicker shift and 50 hp worth of additional holding power for the Allison 1000, 2000 and 2400 transmissions.


Regular VS Aggressive Shift Enhancer

The Aggressive model leads to a slightly more aggressive shift. The pressure is a little higher and makes for a harder shift
