For GM 4L60 Turbine Stator Shaft Teflon Seal Installer/Resizer Transmission Tool

4L60 Turbine Stator Shaft Teflon Seal Installer/Resizer Transmission Tool for GM

This installer and resizer tool is designed to seat and size the Teflon sealing rings on the turbine stator shaft of GM 4L60 series automatic transmissions during rebuilds, helping the rings seal correctly against the forward drum bore.

Overview

This turbine stator shaft Teflon seal installer and resizer for GM 4L60 transmissions presses the Teflon rings onto the stator shaft and sizes them to the correct diameter so they seal properly once the unit is assembled. It is a bench tool for transmission rebuilders and do-it-yourself mechanics working on 4L60, 4L60E, and related units. Using the correct installer avoids nicked or stretched Teflon seals that cause pressure loss and slipping.

Built For Performance

• Sizes Teflon sealing rings to the correct installed diameter
• Seats rings onto the turbine stator shaft without nicking or rolling them
• Hardened steel construction holds up to repeated shop use
• Fits GM 4L60 series turbine stator shaft applications
• Compact bench tool design for one-person operation

On-The-Job Use

• Transmission rebuilds on GM 4L60, 4L60E, and related units
• Replacing Teflon sealing rings on the turbine stator shaft
• Shop bench work where seal damage causes pressure loss and slipping
• Do-it-yourself rebuilds that need proper ring sizing without a press

Good To Know

Q: Why do Teflon seals need to be resized after installation? A: Teflon rings expand when slipped over the shaft and must be compressed back to the correct diameter or they will not seal against the drum bore. This tool sizes them so they seat properly.

Q: Does this tool work on all 4L60 variants? A: It is built for GM 4L60 series turbine stator shaft applications, so confirm your specific unit and shaft dimensions before ordering.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
