You are buying a tool that is used to help install the forward clutch piston on either a 700R4, 4L60, 4L60E or 4L65E transmission.

The tool is an improved version of the OEM tool, it is very simple to use:

  • Lubricate the installer
  • Simply slide the protector over the input housing
  • Install the forward clutch piston assembly (the newer stamped / bonded piston is shown – it will work on both versions)
  • Remove the seal protector from the housing

We also have the seal sizers available and will combine shipping on multiple orders.
