Product Description
A TransGo pressure-regulator bore repair kit for GM 6L45-6L90 series transmissions (6L80, 6L90, 6L45, 6L50) built 2007-2017. It restores proper pressure-regulator function where the bore has worn from extreme pressure, without requiring special tools.
It is sold as a 3-pack, enough to fix three pumps, avoiding replacement of the pump for a worn bore. Installation requires transmission removal and is recommended for an experienced technician.
