set idle rpm in gear to specified idle speed. lf still no good, adjust motor mounts as outlined in enginesection of this manual.
lf the clutch pack is seized or is excessively worn. inspect the other clutches for 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.
lmproper alignment or 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.
lf the l st 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.
Replace the mainshaft if the bushing for the 4th feed pipe is loose or damaged. lf the 4th feed pipe is danFaged or out of round, replace the right side cover.
Replace the mainshaft if the bushing for the 1st feed pipe is loose or damaged. lf the 1st feed pipe is darn-aged or out of round, replace it.
A worn or damaged sprag clutch is mostly a result of shifting the transmission inthe wheels rotate in reverse, such as rocking the vehicle in snow.
or E position while
Inspect for damage and wear:
1. 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 u nder pin ion 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 orwhirring 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, and replace ATF strainer, and thoroughlyclean transmission, flush torque converter, cooler and lines.lf bottom of 3rd clutch is swirled and transmission makes gear noise, replace the countershaft and final drivengear.
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 oroper roors.
Install 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.
See flushing procedure, page 14-187 and 188.
lf the large clutch piston O-ring is broken, inspect the piston groove for rough machining.
lf the l-2 shift valve is stuck closed, the transmission will not upshift. lf stuck open, the transmission hasno 1st gear.
lf the znd orifice control valve is stuck. inspect the 2nd and 3rd clutch oacks for wear.
lf the 3-4 orifice control valve is stuck, inspect the 3rd and 4th clutch oacks for wear.
lf the clutch pressure control valve is stuck closed, the transmission will not shift out of 1st gear.
lf 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.
Inspect the frame for collision damage.

Repair
NOTE: This repair is only necessary if one or more of
the valves in a valve body do not slide smoothly in their
bores. You may use this procedure to free the valves in
the valve bodies.
1. Soak a sheet of #600 abrasive paper in ATF for
about 30 minutes.
Carefully tap the valve body so the sticking valve
drops out of its bore.
CAUTION: lt may b€ necessary to use a small
screwdriver to pry the valve free. Be careful not to
scratch the bore whh the screwdriver.
Inspect the valve for any scuff marks. Use the ATF-
soaked #600 paper to polish off any burrs that are
on the valve, then wash the valve in solvent and dry
it with compressed a ir.
Roll up half a sheet of ATF-soaked paper, and insert
it in the valve bore of the sticking valve.
Twist the paper slightly, so that it unrolls and fits the
bore tightly, then polish the bore by twisting the
paper as you push it in and out.
CAUTION: The valve body is aluminum and doesn't
require much polishing to remove any burrs,

Remove the #600 paper and thoroughly wash the
entire valve body in solvent. then dry it with com-
pressed air.
Coat the valve with ATF, then drop ir into its bore.
It should drop to the bonom of the bore under its
own weight. lf not, repeat step 4, then retest.
VALVE BODY
Remove the valve. then thoroughly clean it and the
valve body with solvent. Dry all parts with com-
pressed air. then reassemble using ATF as a lubri
cant.
