Press down clutch pack with finger and zero dial
indicator.Low/Reverse clutch pack clearance is
0.89 to 1.04 (.035 to .042 inch).
Select the proper low/reverse reaction plate to
achieve specifications:
NOTE: When installing the 2-4 clutch plates and
discs, the orientation should be alternated so thepilot pads of adjacent plates do not align, refer to
(Fig. 254).

NOTE: Verify that Miller Tool 5058 is centered prop-
erly to the 2/4 clutch retainer before depressing the
tool.Press down clutch pack with finger and zero dial
indicator.The 2/4 clutch pack clearance is 0.76 to
2.64mm (.030 to .104 inch).If not within specifica-
tions, the clutch is not assembled properly.There is
no adjustment for the 2/4 clutch clearance.
DETERMINING No. 4 THRUST PLATE
THICKNESSÐINPUT SHAFT END PLAY
To determine the proper thickness of the No. 4
thrust plate, select the thinnest No. 4 thrust plate.
Using petrolatum (Fig. 263) to hold thrust plate in
position, install input clutch assembly. Be sure the
input clutch assembly is completely seated (Fig. 264).
CAUTION: If view through input speed sensor hole
is not as shown above, the input clutches assembly
is not seated properly.
Remove the oil pump O-ring (Fig. 265). You will be
able to install and remove the oil pump and gasket
very easily to select the proper No. 4 thrust plate.

CAUTION: The cooler bypass valve must be
replaced if a transaxle failure has occurred. Do not
reuse old valve or attempt to clean old valve. When
installing bypass valve, insert with O-ring end
towards rear of case.

GENERAL INFORMATION
A-598 MANUAL TRANSAXLE
Safety goggles should be worn at all times
when working on these transaxles.The A-598
manual transaxle uses SAE 5W-30 engine oil, meet-
ing SG and/or SG-CD qualifications, as the factory
fill lubricant. SAE G5 10W-40 engine oil is a suitable
service fill alternative.
This transaxle combines gear reduction, ratio selec-
tion, and differential functions in one unit. It is
housed in a die-cast aluminum case.

TRANSAXLE IDENTIFICATION INFORMATION
The A-598 transaxle model, assembly number,
build date, and final-drive ratio are stamped on a tag
that is attached to the top of the transaxle (Fig. 1).
The last eight digits of the Vehicle Identification
Number (V.I.N.) are stamped on a raised boss on top
of the clutch housing area.

VEHICLES
The A-558 transaxle model, assembly number,
build date, and final-drive ratio are stamped on a tag
that is attached to the top of the transaxle (Fig. 2).NOTE: Certain transaxle assemblies utilize high-
strength steel in various gears. It is imperative that
the correct transaxle assembly number is utilized
when ordering service parts. Do not remove this
tag, so the information is available for future ser-
vice.
The last eight digits of the Vehicle Identification
Number (V.I.N.) are stamped on a raised boss on top

SELECTION OF LUBRICANT
The A-598 manual transaxle uses SAE 5W-30
engine oil, meeting SG and/or SG-CD qualifications,
as the factory fill lubricant. G5 SAE 10W-40 engine
oil is a suitable service fill alternative.Hypoid gear
lube, manual transmission fluid, and/or auto-
matic transmission fluid should not be used in
this transaxle.Hard shifting effort, bearing, gear,
and/or synchronizer failure may occur if incorrect
fluid is used.
