WARRANTY INFORMATION
BASIC NEW CAR LIMITED WARRANTY
All parts of the vehicle, except tires, are covered against defects in factory-supplied materials and workmanship for 12 months or 12,000 miles, CAUT ION: Indicator will cause a squealing or scraping noise, warning that brake pads need replacem ent.
CAUT ION: Continued operation of vehicle with a severe m alfunction could cause converter to overheat, resulting
in possible dam age to converter and vehicle.
CAUT ION: T o avoid possible dam age to vehicle use only ethylene-glycol based coolants with a m ixture ratio from
44-68% anti-freeze. DO NOT use 100% anti-freeze as it will cause the form ation of cooling system
deposits. T his results in coolant tem peratures of over 300° F (149°C) which can m elt plastics. 100% anti-
freeze has a freeze point of only -8° F (-22°C).
CAUT ION: Propylene-Glycol Mixtures has a sm aller tem perature range than Ethylene-Glycol. T he tem perature
range (freeze-boil) of a 50/50 Anti-Freeze/Water Mix is as follows: Propylene-Glycol -26° F (-32°C) - 257° F
(125°C) Ethylene-Glycol -35° F (-37°C) - 263° F (128°C)
CAUT ION: Propylene-Glycol/Ethylene-Glycol Mixtures can cause the destabilization of various corrosion inhibitors.
Also Propylene-Glycol/Ethylene-Glycol has a different specific gravity than Ethylene-Glycol coolant,
which will result in inaccurate freeze point calculations.
WARNING:Many solid state electrical com ponents can be dam aged by static electricity (ESD). Som e will display a
warning label, but m any will not. Discharge personal static electricity by touching a m etal ground point
on the vehicle prior to servicing any ESD sensitive com ponent.
CAUT ION: Never use non-detergent or straight m ineral oil.
WARNING:Relieve fuel system pressure prior to servicing any fuel system com ponent (fuel injection m odels).
WARNING:Halogen bulbs contain pressurized gas which m ay explode if overheated. DO NOT touch glass portion
of bulb with bare hands. Eye protection should be worn when handling or working around halogen
bulbs.
CAUT ION: Before operating vehicle, securely fasten passive shoulder restraints to the em ergency release buckles.
T he buckle fits in only one way. Ensure to position it properly.
CAUT ION: Always disconnect the fan m otor when working near the radiator fan. T he fan is tem perature controlled
and could start at any tim e even when the ignition key is in the OFF position. DO NOT loosen or rem ove
radiator cap when cooling system is hot.
WARNING:Keep hands away from radiator fan. Fan is controlled by a therm ostatic switch which m ay com e on or
run for up to 15 m inutes even after engine is turned off.

1991-92 ST EERING Ford Motor Co. - Steering - Power Rack & Pinion
DESCRIPTION & OPERATION
Power steering system consists of a rack and pinion steering gear, valve body, power steering pump, fluid reservoir and interconnecting
hydraulic lines. Pressure and return lines from pump are connected to valve body. A vane-type power steering pump draws fluid from the
steering reservoir. Fluid is compressed by rotor and vanes inside steering pump and sent to steering gear. Pressure is monitored and controlled
by a pressure switch and a control valve located inside of steering pump.
TROUBLE SHOOTING

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
.

LINE PRESSURE TEST SPECIFICATIONS (ASPIRE)
LINE PRESSURE TEST SPECIFICATIONS (ALL EXCEPT ASPIRE)
LINE PRESSURE CUT-BACK TEST
1. Connect oil pressure gauges to line pressure and governor pressure ports. See Fig. 6
. Position gauges so they can be seen from driver's
seat.
2. Connect a hand-held vacuum pump to vacuum modulator. See Fig. 6
. Position vacuum pump so it can be operated from driver's seat.
With shift lever in "D", gradually increase engine RPM and observe pressure gauge readings. Record results.
3. With shift lever in "D", gradually increase engine RPM, and apply 8 in. Hg to vacuum modulator. When line pressure reading suddenly
decreases, observe the governor pressure gauge. Refer to LINE PRESSURE CUT
-BACK TEST SPECIFICATIONS .
4. If governor pressure gauge readings are not within specifications, ensure rod in vacuum modulator is installed. If a rod is installed, rod
length may be incorrect or vacuum throttle valve is sticking. See VACUUM THROTTLE VALVE DIAPHRAGM (MODULATOR)
under TESTING.
LINE PRESSURE CUT-BACK TEST SPECIFICATIONS
GOVERNOR PRESSURE TEST
1. Attach oil pressure gauge to governor pressure check port. See Fig. 6
. Position gauge so that it may be seen from driver's seat. Shift
transaxle into "D" and road test vehicle.
2. Accelerate vehicle smoothly and record governor pressure readings at 20, 35 and 55 MPH. See GOVERNOR PRESSURE
SPECIFICATIONS . If pressure gauge readings are not within specifications, check for fluid leakage in line pressure hydraulic circuit
and/or governor pressure hydraulic circuit. Also check for a faulty governor.

REMOVAL & INSTALLATION
See the appropriate TRANSMISSION REMOVAL & INSTALLATION - A/T article in this section. Refer to the following menu:
TORQUE CONVERTER
The torque converter is a sealed unit and cannot be serviced. Check for cracked or worn ring in seal area. Measure bushing in converter boss.
If I.D. is larger than 2.090" (53.08 mm) on Aspire, 1.302" (33.075 mm) on Festiva and Tracer, replace torque converter. If metal particles are
found in ATF, replace torque converter. To clean torque converter, flush with solvent, drain and flush with ATF and drain ATF.
TRANSAXLE DISASSEMBLY
1. Remove torque converter. Attach transaxle to appropriate holding fixture. Remove park/neutral switch, kickdown solenoid and vacuum
modulator with rod. Remove oil dipstick and tube. Remove speedometer driven gear retaining bolt and lift out gear assembly. Remove
oil pump drive shaft and turbine shaft.
2. Remove oil pan. Remove valve body. DO NOT lose check ball and spring. Position transaxle with oil pump facing downward. With
flat-blade screwdriver inserted in wide slot between front clutch drum and sun shell, pry down on front clutch drum. Do this seve r a l
times as you rotate assembly 2 complete revolutions.
3. Using a feeler gauge, measure front clutch drum end play. See Fig. 7
. Check clearance of small slot between front clutch drum tabs and
