6L45 6L50 6L80 6L90 Reprogramming Kit Drive Tow Race

Product Description

TransGo performance kit for 6L45, 6L50, 6L80 and 6L90 transmissions in trucks and performance applications, for drive, tow and race use. It raises maximum main line pressure and uses a more aggressive pressure curve.

The valve body and pump components are calibrated to keep the factory shift feel at light to medium throttle, with progressively firmer upshifts through WOT.

How it works

The kit gives quick, clean, firm shifts with increased holding capacity, and faster line rise when adding throttle.

Patent-pending parts rework the 2-6, 3-5-R and 4-5-6 clutch regulator and boost valves for faster, cleaner shifts with increased holding capacity, without bumps, clangs or bangs and without software tuning.

Optional tuning with HPtuners or EFI Live adds 1-2 and 2-3 hard-throttle tire chirping shifts and simple computer tuning of the shift time tables.
