FORM-IN-PLACE GASKET (FIPG)
This transmission has several areas where the form-
in-place gasket (FIPG) is used for sealing. To ensure 
that the FIPG fully serves its purpose, it is necessary 
to observe some precautions when applying it. Bead 
size, continuity and location are of paramount impor-
tance. 
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 fluid passages. To 
prevent leaks or blocking of passages, therefore, it is 
absolutely necessary to apply the FIPG evenly with-
out a break, while observing the correct bead size.
FIPG hardens as it reacts with the moisture in the 
atmospheric air, and it is usually used for sealing 
metallic flange areas.

.

Disassembly
Parts sealed with a FIPG can be easily removed 
without need for the use of a special method. In 
some cases, however, the FIPG in joints may have to 
be broken by tapping parts with a mallet or similar 
tool. 

.

Surface Preparation 
Thoroughly remove all substances deposited on the 
FIPG application surface, using a gasket scraper. 
Make sure that the FIPG application surfaces is flat 
and smooth. Also make sure that the surface is free 
from oils, greases and foreign substances. Do not fail 
to remove old FIPG that may remain in the fastener 
fitting holes.

.

FIPG Application
Applied FIPG bead should be of the specified size 
and free of any break. FIPG can be wiped away 
unless it has completely hardened. Install the mating 
parts in position while the FIPG is still wet (in less 
than 10 minutes after application). Do not allow FIPG 
to spread beyond the sealing areas during installa-
tion. Avoid operating the transmission or letting oils 
or water come in contact with the sealed area before 
a time sufficient for FIPG to harden (approximately 
one hour) has passed. 
FIPG application method may vary from location to 
location. Follow the instruction for each particular 
case described later in this manual.
