REMOVAL AND INSTALLATION (Continued)

(22) Remove lower starter bolt.
(23) Remove engine wiring harness clip.
CAUTION: Always use a safety chain when remov-
ing or installing transaxle assembly.
(24) Place a transmission jack under the transmis-
sion
(25) Remove the transaxle lower dust cover.
(26) Remove the access cover in right splash shield
to access torsional damper bolt.
(27) Remove drive plate to modular clutch bolts
while holding torsional damper bolt with socket and
ratchet. To avoid distortion of the drive plate, remove
the modular clutch bolts a few turns at a time. Use a
crisscross pattern until all bolts are loosened.
(28) Unbolt rear engine mount through bolt and
two (2) mount bolts.
(29) Remove the left front fender splash shield.
(30) Unbolt left engine mount through bolt and
unbolt mount from the transaxle.(31) Remove front engine mount (Fig. 60) and (Fig.
61).
(32) Lower the transaxle and modular clutch.
To service the drive plate, refer to Group 9, Engine.
INSTALLATION
(1) Position the modular clutch assembly onto the
input shaft of the transaxle (Fig. 62).
(2) To reinstall transaxle, reverse removal proce-
dure making certain to align the elongated hole in
the drive plate with the modular clutch bolt hole that
has the white paint mark.

REMOVAL AND INSTALLATION (Continued)

NOTE: To avoid distortion of the drive plate, bolts
should be tightened a few turns at a time. Use a
crisscross pattern until all bolts are seated. Tighten
modular clutch plate bolts to 74 N´m (55 ft. lbs.).
NOTE: Lower control arm pinch bolts must be
installed with the bolt head rearward of the ball
joint.
(3) Fill transaxle to the proper level with the spec-
ified lubricant.
(4) While the vehicle is elevated slightly, run the
transaxle through all the forward gears. Apply
brakes and shift into reverse. Run the transaxle
through reverse gear.
(5) Check the transaxle for leaks and recheck the
level of the transaxle lubricant.
DISASSEMBLY AND ASSEMBLY
TRANSAXLE
The A-598 transaxle (Fig. 63) is similar to the
A-523, A-568 transaxle with the following exceptions.
The major differences are that the input shaft is sup-
ported by ball and roller bearings and the intermedi-
ate shaft is supported by tapered roller bearings.
Also the front intermediate bearing will not clear the
final drive gear for disassembly or reassembly.
In vehicle service is limited to:
²Shift cover components
²Sealing external joints and seals
²Service of 5th gear set and synchronizer
DISASSEMBLY
(1) Remove engine mount bracket (Fig. 64).
(2) Remove differential bearing retainer (Fig. 65).
(3) Remove extension housing (Fig. 66).
(4) Remove differential cover with soft-faced ham-
mer (Fig. 67).

DISASSEMBLY AND ASSEMBLY (Continued)

NOTE: Two of the bolts retaining the shift cover are
shouldered. Mark the bolts and the location (Fig.
71).
(7) Remove shift cover splash shield (Fig. 73).(8) Remove shift detent springs (Fig. 74) and roll-
ers (Fig. 75).
NOTE: On some A-598 transaxles all four detent
springs are of the same color and spring tension.
On other A-598 transaxles, three identical springs
are used on the forward gear detents, while the
reverse detent spring is a different tension and
color.
