Operating line pressure is the lifeblood of any automatic transmission by providing the clamping force on the clutches and bands. Often times, increasing line pressure is a requirement when increasing driveline output. The new TCI 4L60E boost valve assembly provides you the means of elevating your line pressure while also addressing wear issues that may actually have your transmission running at a lower level of pressure than GM intended.

Boost valve features: larger diameter over stock that yields 10-15% higher line pressure, o-rings on boost sleeve which prevents loss of boost signal pressure, sleeve constructed from Alcoa Deltalloy 4032 & hard-coat anodised which prevents wear between the mating parts.
