Inspect the pump housing and support components.
Replace the housing or support if the seal ring
grooves or machined surfaces are worn, scored, pit-
ted, or damaged.
Replace the pump gears if pitted, worn chipped, or
damaged. Inspect the thrust washer for wear or dam-
age. Replace the washer if necessary.Note that the
inner gear used in 1993 and later 30RH/32RH oil
pumps has a new design drive lug. The new de-
sign incorporates tapered drive flats instead of
the square lug used previously. The torque con-
verter hub has also been redesigned to accept
the new drive flats. If pump gear replacement is
necessary, be very sure to order and install the
correct style gears.
Inspect the pump and reaction shaft support bush-
ings. Minor bushing wear is acceptable. Replace the
bushings only if scored, or severely worn.
Install the gears in the pump housing and measure
end clearance with a feeler gauge and straightedge
(Fig. 46). Clearance should be 0.010 - 0.06 mm
(0.0004 - 0.0025 in.).
Measure clearance between the outer gear and the
pump body (Fig. 47). Clearance should be 0.08 - 0.19
mm (0.0035 - 0.0075 in.).
Measure gear tooth clearance with a feeler gauge.
Align one tooth of the outer gear in inner gear andmeasure clearance (Fig. 48). Clearance should be
0.08 - 0.19 mm (0.0035 - 0.0075 in.).

REAR BAND, LOW-REVERSE DRUM AND REAR
SUPPORT INSTALLATION
A different rear band and linkage is used in 30RH
and 32RH transmissions.
The 30RH transmission has a single wrap band,
one pivot pin and a band link to connect the lever
(Fig. 124). The lever adjusting screw is in direct con-
tact with the servo piston. A strut is used to connect
the lever to the band lug.
The 32RH transmission has a double wrap band, a
pivot pin, and a reaction pin (Fig. 125). The band le-
ver pivots against a lug on the band. A strut is not
used. The reaction pin functions as the stop, or locat-
ing mechanism for the band lower lug.
