TransBrake Kit
Fits: 4L80E and 4L85E
The TransGo TransBrake Kit delivers the ideal combination of street reliability and race-ready performance. It retains factory electronic shift controls for everyday driving while adding manual up-shift capability for track use.
With lightning fast release for hard launches in both D3 (auto up-shifts) and D1 (manual up-shifts), this kit offers total control.
A built-in safety switch prevents accidental activation unless the transmission is in first gear and constant line pressure ensures maximum holding power throughout the entire range.
To ensure maximum holding power the kit is designed to have fixed 180 psi of line pressure forward with boosted reverse pressure of 250 psi.
