You are buying a tool that is used to help install the intermediate clutch piston on either a Turbo 400, 3L80, 4L80E or 4L85E transmission.

The tool replaces the crack prone plastic GM tool, it is very simple to use:

  • Lubricate the installer
  • Simply slide the protector over the center hub in either the forward or direct clutch drum
  • Install the forward or direct clutch piston assembly (the aluminum cast piston is shown – it will work on both the stamped and cast versions)
  • Remove the seal protector from the housing
  • 100% made in USA
