Valve Body: Service and Repair

TRANSMISSION VALVE BODY ASSY (A750E/A750F)

REPLACEMENT

CAUTION: When working with FIPG material, you must observe the following guidelines.
^ Using a razor blade and gasket scraper, remove all the old FIPG material from the gasket surfaces.
^ Thoroughly clean all components to remove all loose material.
^ Clean both sealing surfaces with a non-residue solvent.
^ Apply FIPG in an approximately 1 mm (0.04 inch) wide bead along the sealing surface.
^ Parts must be assembled within 10 minutes of application. Otherwise, the FIPG material must be removed and reapplied.
