(14) Measure input shaft end play. Place transaxle
so input shaft is vertical. Set up end play set and
dial indicator as shown in (Fig. 27). Input shaft end
play should be within 0.13-0.64 mm (0.005-0.025
in.) If outside of this range, a #4 thrust plate change
is required. Record indicator reading for reference
upon reassembly. (15) Remove oil pump-to-case bolts (Fig. 28).
CAUTION: Be sure input speed sensor is removed
before removing oil pump. (16) Install pullers Tool C-3752 as shown in (Fig.
29).

(24) Remove front carrier/rear annulus assembly
and #6 needle bearing (Fig. 38).
(25) Remove rear sun gear and #7 needle bearing
(Fig. 39).
NOTE: The number 7 needle bearing has three anti-
reversal tabs and is common with the number five
and number two position. The orientation should
allow the bearing to seat flat against the rear sun
gear (Fig. 40). A small amount of petrolatum can be
used to hold the bearing to the rear sun gear. (26) Setup tool 5058 as shown in (Fig. 41). Com-
press 2/4 clutch return spring (just enough to remove
snap ring) and remove snap ring.
NOTE: Verify that Tool 5058 is centered properly
over the 2/4 clutch retainer before compressing. If
necessary, fasten the 5058 bar to the bellhousing
flange with any combination of locking pliers and
bolts to center the tool properly.
NOTE: The 2/4 Clutch Piston has bonded seals
which are not individually serviceable. Seal replace-
ment requires replacement of the piston assembly.
