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
Stall Speed rpm:
Specitication: 2,550 rpm
S€rvice Limit: ?,400 - 2.700 rpm

1. Start the engine, and shift to E or @ position.
2. Run the engine at 2,000 rpm, then measure line pressure. Higher pressure may be indicated if measurements aremade in shift lever positions other than E or @ position.
shift to E ('97 - 98) or E ('99 - oo) position and hold the engine at 2.ooo rpm, then measure 1st clutch pressure.
Shift to E position and hold the engine at 2,000 rpm, then measure lst-hotd ctutch Dressure.
