4. Place the transmission on the
workbench (
Figure 7-15
) and
remove the oil pan and oil filter.
NOTE
The type of debris found in the bottom of
the oil pan is indicative of the type of
internal damage you may find in the
transmission.
5. Remove the bolts holding the
valve body to the transmission. As
you lift off the valve body, note the
position of all valve body parts,
springs, oil feed tubes, linkage
attachments, and check balls.
6. Remove the vacuum modulator,
push rod, and throttle valve from
the case at this time.
Figure 7-15 - Transmission in a
cradle.
7. Remove the bolts holding the extension housing to the case. Extension housings
are sometimes called tailshaft housings. The extension housing should pull off
over the output shaft after the bolts are removed.
8. Remove the governor. This step only applies to governors mounted on the output
shaft.
9. Remove the front oil pump oil seal (
Figure 7-16
). It is generally easier to remove
the seal before the oil pump is removed (
Figure 7-17
) because the extra weight
of the transmission assembly allows you to use the slide hammer more
efficiently. You should always replace the seal when the pump is serviced.

pump seal.
