NOTES
See flushing procedure, page l4-264 and 265,
BSet idle rpm in gear to specified idle speed. lf still no good, adjust motor mounts as outlined in enginesection of this manual.
clf the large clutch piston O-ring is broken, inspect the piston groove for rough machining.
Dlf the clutch pack is seized or is excessively worn. inspect the other clutches fot wear, and check the orificecontrol valves, CPC valve, and linear solenoid for free movement.
lf the linear solenoid is stuck, inspect the clutches for wear.
lf the 1-2 shift valve is stuck closed. the transmission will not upshift. lf stuck open, the transmission hasno lst gear.
Hlf the 2nd orifice control valve is stuck, inspect the 2nd and 3rd clutch Dacks for wear.
lf the 3-4 orifice control valve is stuck, inspect the 3rd and 4th clutch packs for wear.
Jlf the clutch pressure control valve is stuck closed. the transmission will not shift out of lst gear.
Klmproper alignment of main valve body and torque converter housing may cause ATF pump seizure. Thesymptoms are mostly an rpm-related ticking noise or a high-pitched squeak.
Llf the ATF strainer is clogged with particles of steel or aluminum, inspect the ATF pump and differentialpinion shaft. lf both are OK and no cause for the contamination is found, replace the torque converter.
Mlf the lst clutch feed pipe guide in the end cover is scored by the mainshaft. inspect the ball bearing forexcessive movement in the transmission housing. lf oK, replace the end cover as it is dented. The o-rinounder the guide is probably worn.
N' Replace the mainshaft if the bushing for the 4th feed pipe is loose or damaged, lf the 4th feed pipe is darrFaged or out of round. replace the end cover.' Replace the mainshaft if the bushing for the l st feed pipe is loose or damaged. lf the 1st feed pipe is dam-aged or out of round, replace it.
oA worn or damaged sprag clutch is mostly a result of shifting the transmission in E!. E, or E positionwhile the wheels rotate in reverse. such as rocking the vehicle in snow.
PInspect the frame for collision damage.
lnspect for damage and wear:
l. Reverse selector gear teeth chamfers.
2. Engagement teeth chamfers of countershaft 4th and reverse gear.
3. Shift fork for scuff marks in center.
4. Differential pinion shaft for wear under pinion gears.
5. Bottom of 3rd clutch for swirl marks.
Replace items 1, 2, 3. and 4 if worn or damaged. lf transmission makes a clicking, grinding, or whirring noise,also replace mainshaft 4th gear, reverse idler gear, and countershaft 4th gear in addition to 1,2, 3, or 4.lf differential pinion shaft is worn, overhaul differential assembly, replace ATF strainer, and thoroughly cjeantransmission, flush torque converter. cooler, and lines,lf bottom of 3rd clutch is swirled and transmission makes gear noise. replace the countershaft and final drivenoear,
Be very careful not to damage the torque converter housing when replacing the main ball bearing. you
may also damage the ATF pump when you torque down the main valve body. This will result in ATF pumpseizure if not detected. Use the Drooer tools.
SInstall the main seal flush with the torque converter housing. lf you push it into the torque converterhousing until it bottoms out, it will block the fluid return passage and result in damage.

Stall Speed
Test
CAUTION:
. To prevent transmission damage, do not te3t stall speed for mors than 10 s€€onds at a time'
. Do not shift the lever while raising th€ engine spsed.
. Be sure to remove tho pressuro gauge bofore testing stall speed,
1. Before testing, check the transmission fluid level, s€e page 14-160.
2. Engage the parking brake and block all four wheels
3. Connect the tachometer, and start the engane.
4. Make sure the Ay'C switch is OFF
5. After the engine haswarmed upto normal operating temperature (the radiator fan comes on),shiftinto@ position.
6. Fully press the brake pedal and accelerator for 6 to 8 seconds, and note engine speed '
j. A|ow 2 minutes for cooling, then repeat the test in E, E ('97 - 98). E {'99 - 00}, and E positions. Stall speed should
be the same in E, E, E, tr. and E positions

Front Toe Inspection/Adjustment
Use commercially-available computerized four wheel
alignment equipment to measure wheel alignment (caster,
camber, toe, and turning angle). Follow the equipment
manufacturer's instructions,

1.Check the tire pressure.
Center the steering wheel spokes.
Check the toe with the wheels pointed straight
ahead.
Front toe-in: 0 i 3 mm {0 t 1/8 inl
- lf adjustment is required, go on to step 4.
- lf no adjustment is required, remove alignment
equipment.
Loosen the tie-rod locknuts, and turn both tie-rods
in the same direction until the front wheels are
pointing straight ahead.
5.Turn both tie-rods equally until the toe reading on
the wheel alignment computer is correct.
After adjusting, tighten the tie-rod locknuts and
reposition the tie-rod boots if they are twisted or
displaced.

Rear Toe Inspection/Adjustment
Use commercially-available computerized four wheel
alignment equipment to measure wheel alignment (caster,
camber. toe, and turning angle). Follow the equipment
manufacturer's instructions.
Release parking brake to avoid an incorrect mea-
surement.
Check the toe.
Ro8r toe-in: 2 :1 mm {lN l/16:t 1/16 in,
- lf adjustment is required, go to step 2.
- lf no adiustment is required. remove alignment

Before adjustment, note the locations of adjusting
bolts on the right and left compensator arms.
Loosen the adjusting bolts, and slide the compen-
sator arm in or out. as shown, to adiust the toe.

FLANGE BOLT'10 x 1.5 mm
COMPENSATOR ARM
Example: After the rear toe inspection, the wheel is 2
mm (0.08 in) out of the specification.- Move the arm so the adjusting bolt moves 2 mm
{0.08 in) inward from the position recorded before the
adjustment.- The distance the adjusting bolt is moved should be
equal to the amount out-of-specification.

A/G System Service
Performance Test
The performance test will helD determine if the air con-
ditioner system is operating within specifications.
Use only service equipment that is U.L.-listed and is cer-
tified to meet the requirements of SAE J2210 to remove
HFC-134a (R-134a) from the air conditioner svstem.
CAUTION: Exposure to air condiiioner r€trigerant and
lubricant vapor or mist can irritate €yes, nose and
throat. Avoid bre8thing the air conditioner retrige.ant
and lubricant vapor or mist,
lf accidental system discharge occurs. ventilate work
area before resuming service.
R-134a service equipment o. vehicle air conditioner sys-
tems should not be pressure tested or leak tested with
comDressed air.
@ some mixtur€s ol air and R-134a have becn
shown to be combuslible at olsvated pressures and can
result in lire or explosion causing iniury or property
damage. Never use compressed air to prgssure test R-
13i[a service equipment or vehicle air conditioner sys.
tems.
Additional health and safety information may be obtained
from the refrigerant and lubricant manufacturers.
Recovory/Recycling/charging station
LOW.PRESSURESIDE
1.Connect a R-134a refrigerant recover/recycling/
charging station to the vehicle, as shown. following
the equipment manufacturer's instructions,
Insen a thermometer in the center air vent. Determine
the relative humidity and air temperature.
Test conditions:
. Avoid direct sunlight.
o Open hood.
. open front doors.
. Set the temperature control dial on MAX COOL,
the mode control dial on VENT and the reci.cula-
tion control switch on RECIRCULATE.
. Turn the A,/C switch on and the fan switch on
MAX.
. Run the engine at 1,500 rpm.
. No driver or passengers in vehicle
After running the air conditioning for 10 minutes
under the above test conditions, read the deliverv
temperature from the thermometer in the dash vent
and the high and low system pressure from the Ay'Cgauges.
