# RTV SEALANT/OIL PAN GASKET REPLACE LATEX COATED CORK

THM 125 AND 125C TRANSMISSIONS ARE NOW BEING BUILT WITH R.T.V. SILICONE SEALANT ON THE VALVE BODY COVER AND BOTTOM PAN IN PLACE OF THE CORK GASKET. THE FLANGE ON BOTH THE VALVE BODY COVER AND THE BOTTOM PAN HAS BEEN REDESIGNED TO ELIMINATE THE STIFFENING RIB, (SEE FIGURE 1) MAKING THE FLANGE FACE FLAT. OIL PANS WITH RAISED STIFFENING RIBS ON THE FLANGE, AS IN FIGURE 1, MUST NOT BE ASSEMBLED WITH R.T.V. SEALANT. ** SEE BULLETIN **

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
