You are buying a tool that is used to install the manual shaft seal on any GM late model transmission. It fits, but not limited to:
- THM 4L80E, 4L85E
- THM 4L60E, 4L65E, 4L70E
It is very simple to use:
- Lubricate the installer
- Simply slide the seal over the tool
- Insert the small end into the manual shaft hole
- Gently tap the seal into the counterbore
This tool will hold the seal square to the bore and press on the OD of the seal, thus eliminating leaks and ruined seals.
We also have the seal sizers available and will combine shipping on multiple orders.
