FORM-IN-PLACE GASKET
The transmission has several areas where the form-in-place gasket (FIPG) is in use. To ensure that the
gasket fully serves its purpose, it is necessary to observe some precautions when applying the gasket.
Bead size, continuity and location are of paramount importance. Too thin a bead could cause leaks. Too
thick a bead, on the other hand, could be squeezed out of location, causing blocking or narrowing of
the fluid feed line. To eliminate the possibility of leaks from a joint, therefore, it is absolutely necessary
to apply the gasket evenly without a break, while observing the correct bead size.
Since the RTV hardens as it reacts with the moisture in the atmospheric air, it is normally used in the
metallic flange areas.
DISASSEMBLY
The parts assembled with the FIPG can be easily disassembled without use of a special method. In some
cases, however, the sealant between the joined surfaces may have to be broken by lightly striking with
a mallet or similar tool. A flat and thin gasket scraper may be lightly hammered in between the joined
surfaces. In this case, however, care must be taken to prevent damage to the joined surfaces.
Surface Preparation
Thoroughly remove all substances deposited on the gasket application surfaces, using a gasket scraper
or wire brush. Check to ensure that the surfaces to which the FIPG is to be applied is flat. Make sure
that there are no oils, greases and foreign substances deposited on the application surfaces. Do not forget
to remove the old sealant remaining in the bolt holes.
FORM-IN-PLACE GASKET APPLICATION
When assembling parts with the FIPG, you must observe some precautions, but the procedures is very
simple as in the case of a conventional precut gasket.
Applied FIPG bead should be of the specified size and without breaks. Also be sure to encircle the bolt
hole circumference with a completely continuous bead. The FIPG can be wiped away unless it is hardened.
While the FIPG is still moist (in less than 15 minutes), mount the parts in position. When the parts are
mounted, make sure that the gasket is applied to the required area only. In addition, do not apply any
oil or water to the sealing locations or start the engine until a sufficient amount of time (about o n e hour)
has passed after installation is completed.
The FIPG application procedure may vary on different areas. Observe the procedure described in t h e
text when applying the FIPG.
