Transmission Valve Body ASSY: Replacement

WARNING: This page is about a different car, the 2004 Lexus LS 430. However, it is still accessible from the selected car via links, so may be relevant.

CAUTION: When working with FIPG material, perform the following:

Using a razor blade and gasket scraper, remove all the old FIPG material from the gasket surfaces.
Thoroughly clean all components to remove any loose material.
Clean both sealing surfaces with a non-residue solvent.
Apply FIPG in a continuous line width approximately 1 mm (0.04 in.) along the sealing surface.
Parts must be assembled within 10 minutes of application. Otherwise, the FIPG material must be removed and reapplied.
