Engineered for heavy-duty work or performance trucks, the all new ALLISON-11UP performance valve body Reprogramming Kit™ includes pump and valve body components to provide maximum holding capacity in all clutch packs and lockup—stock or tuned.

Increased TCC holding capacity
Maintains factory shift feel at light to medium throttle with progressively firmer upshifts through WOT
