APPLICATION
DESCRIPTION
The transaxle consists of 3 main units: automatic transaxle, torque converter and differential assembly. The automatic transaxle consists of
front and rear clutches, one-way clutch, low-reverse brake assembly, oil pump and hydraulic controls (valve body and servo piston
assemblies). The valve body is controlled by the governor valve, vacuum throttle valve diaphragm (modulator) and kickdown solenoid. The
torque converter on the Aspire model is a mechanically operated (centrifugal type) torque converter clutch. See Fig. 1
.

See STALL SPEED SPECIFICATIONS .
Testing Procedures
1. With engine at normal operating temperature, tachometer installed and parking and service brakes applied, perform transaxle stall test in
"D", "2", "1" and "R" ranges at full throttle and note maximum RPM obtained. Correct stall speed should occur at specified RPM. See
the STALL SPEED SPECIFICATIONS
.
STALL SPEED SPECIFICATIONS
2. If stall speed is too high in all shift ranges, the following components may be faulty:
Worn Oil Pump.
Oil leakage from oil pump, valve body or transaxle case.
Sticking pressure regulator valve.
3. If stall speed is too high in "D", "2" and "1", the following component may be faulty:
Slipping rear clutch.
4. If stall speed is too high in "D", the following component may be faulty:
Slipping one-way clutch.
5. If stall speed is too high in "2", the following components may be faulty:
Slipping intermediate band.
6. If stall speed is too high in "R", the following components may be faulty:
Slipping Low/Reverse Clutch.
Slipping Front Clutch.
7. If stall speed is too low in all shift ranges, the following components may be faulty:
Slipping torque converter one-way clutch.
ROAD TEST
1. Before road test, ensure that fluid level, fluid condition and control linkage adjustments are okay. During test, transaxle should upshift
or downshift at about same speed as specified. See appropriate SHIFT SPEED SPECIFICATIONS
.
2. All shifts may vary slightly due to production tolerances or tire size. The quality of the shifts are more important. All shifts should be
smooth, responsive and with no slippage or engine flare. Slippage or engine flare in any gear usually indicates clutch or band problems.
3. The slipping clutch or band in a particular gear can usually be identified by noting transaxle operation in other selector positions and
comparing internal units which are applied in these positions. See CLUTCH & BAND APPLICATION
.

Inspection
Remove seal rings and inspect piston for damaged or worn piston. Ensure spring free length is 1.890" (48.00 mm). If less than specified,
replace spring. Install new seal rings on piston and servo retainer.
DIFFERENTIAL
Disassembly
1. Remove ring gear retaining bolts and ring gear. Using hammer and pin punch, drive out roll pin. See Fig. 12. Push out pinion gear shaft.
Remove pinion and side gears, with washers, from differential housing.
2. Using appropriate puller, remove side bearings from differential housing. DO NOT remove speedometer drive gear unless damaged.
Removal will damage speedometer drive gear.
Inspection
Check all gears for signs of excessive wear or damage. Check differential gear case for cracks or other damage. Replace as needed.
Reassembly
1. Reverse removal procedure to reassemble. Measure side gear and pinion gear backlash by inserting drive shafts into differential side
gears and supporting shafts in "V" blocks. Position dial indicator with plunger resting on teeth of pinion gear. See Fig. 13
. Measure
backlash. Repeat procedure with plunger on other pinion gear.
2. Backlash readings should be less than .004" (.10 mm). If backlash is not within specification, adjust backlash by changing thrust
washers. Thrust washers are available in .079" (2.00 mm), .083" (2.10 mm) and .087" (2.20 mm) thicknesses. Use thrust washers of t h e
same thickness on both sides whenever possible.
