Fluid Pump: Assembly

NOTE: Minor burrs and scoring may be removed with crocus cloth. If damage is found, install a new assembly.

Inspect the fluid pump components for the following:
- Pump body and case for burrs
- Fluid passages for obstructions

NOTE: Check and make sure that the garter spring in the seal has not popped off of the converter hub seal.

Install a new seal onto the Torque Converter Fluid Seal Installer.
